The professional activity of our organization covers a wide area of designing various objects, among which is the design of oil refineries (refinery). The information specified in the application is the basis for creating a refinery project, which can be represented by a typical, complex or non-standard structure. Services provided by our organization include:
Our responsibilities in terms of general design. We are responsible for the creation and implementation of all necessary approvals regarding the project, including the processes of field supervision, but at the same time, the processes of manufacturing and assembling the refinery are carried out by another organization.
The process of developing individual fragments of a set of construction documentation. Here, the necessary sections of the project are being worked out, examples of which can be: KM - metal structures; KMD - metal detailing structures; KZh - reinforced concrete structures.
General contract function. The position of the general contractor is to perform general contractor certain tasks in both design, installation and production matters, including the procedure for obtaining all approved approvals and documents allowing the commissioning of these refineries.
Material costs are not incurred by the client when providing services for conducting a preliminary assessment of the proposed project, calculating the estimated cost and estimated time frame for the execution of these works in our organization. If you have any questions, you can contact our staff for complete and detailed information.
To submit an application for the execution of the design of an oil refinery, as well as the implementation of work under the general contract, is carried out through the following methods:
Providing design information the customer can accompany in a suitable and convenient form, for example, in a printed format on paper, or use an electronic medium (USB drive, attach a file to an email, etc.).
If the application was made by you on the website of our organization or sent by e-mail, you will be informed of its receipt as soon as possible.
Significant indicators that can affect the timing of the design of oil refineries are the complexity of the configuration of the structure and the upcoming scope of design. The components of the documentation submitted for development have an impact on the duration of the refinery design. The timing is set for each object on an individual basis. After determining the terms, the representative of our organization offers a commercial offer, which is accompanied by a detailed schedule of the calendar plan in a graphic image. It contains data on the periods of work carried out for each specific part of the project and their payment. Mostly, the initial design stage is linked exactly to the moment of payment of the advance payment, these conditions are prescribed in the contract.
Our organization carries out the design of the refinery in the shortest possible time, but not less than 3 days. Evaluation of the project task submitted to us takes no more than 15 minutes for simple projects. Evaluating projects with increased complexity or degree of uniqueness involves a longer process.
Accordingly, each project is subject to individual settlement operations, the value of which varies depending on various factors. The evaluation criteria is the composition of the required design work, the need for production work and the installation process. The complexity of the project and the degree of workload of the department during the order period are taken into account.
With all this, there is no clear line in delimiting the above price categories, due to the fact that even elementary simple projects can be subject to special requirements. This may apply both to the peculiarities of documenting, and to the need for certain additional work, which increases total cost project. Also, in addition to complexity, it is necessary to take into account such factors as the lack of repeatability of refinery designs. This leads to the fact that at the design stage labor costs increase, the complexity of manufacturing and installation processes increases. Based on the presence of such specifics, pricing for each project is based on an individual approach.
Initial information makes it possible to determine the level of project readiness.
These materials can be provided in any form convenient for the customer. So, the application might look like this:
A set of drawings for metal structures (CM) is subject to mandatory peer review. Having received approval confirmation, you can proceed to the development of KMD - a set of drawings for metal detailing structures. A package of this documentation will later be required directly for production by the manufacturer.
The contract prescribes the maintenance of the payment procedure between the design organization and the customer. The rules of the contract stipulate all stages of payment for the work performed, their types and volumes. The approximate payment scheme can be presented as follows:
The above payment scheme for services may differ due to the possible difference in the submitted projects. Depending on how much work will be carried out, some items may be omitted, or new ones may be added. Features of the work are present when interacting with foreign clients. For example, the calculation of the amount of payment for the work performed as a whole is based on the cost of 1 working hour.
A certain design object is inherent in the presence of several stages of the life cycle, however, some of the stages are applied only to objects that are subject to expert analysis.
The stages of the life cycle of an oil refinery can be represented in the following regulations:
Most of the customers put forward requests for completely finished refinery buildings with a clear requirement for the availability of operational characteristics (area, number of storeys, etc.). For the client, the result is important at the lowest price and high efficiency in the use of the facility. But such issues as design features, complexity, the essence of design and manufacture, the cost of installation work, as a rule, are not of great interest to him.
In order to make it easier for you to determine the most suitable option in combination of design characteristics, materials and technologies for building a refinery, our organization can offer you a free consultation. Our lead engineer will consult for you with the presentation of comprehensive and competent information about the positive and negative aspects of each individual design solution. It will help you make the most rational choice. To determine a suitable design scheme, there is a need to simultaneously calculate a number of such schemes based on different solutions. An example of such an approach is the choice of ceilings for refineries, since there are several types of floors: based on a rolled beam, a welded beam of variable section, and thin-walled elements. The choice problem is that without a calculation it is not possible to determine which option will be the most economically viable for a particular project. To this end, three schemes are calculated at once, which helps to achieve about 5% savings, and this indicator is quite significant, given the price of the entire project.
Carrying out such calculations is an extremely important stage in the design of an oil refinery, where the safety of its operation is due to the correctness and accuracy of the design actions. Their essence lies in the error-free calculation of the load that will be borne by each detail of the refinery structures. This will make it possible to make a clear selection of the section for such a load, subject to all relevant standards adopted in the Russian Federation. The calculation is influenced by such a significant factor as the location of the refinery. They affect the calculation of loads, since atmospheric influences, the frequency and level of precipitation, and seismicity cannot be ignored.
Refinery design calculations are based on the following steps:
Qualified specialists of our organization are able to calculate any refinery design, regardless of their level of complexity. Settlement transactions and actions for each project are based on two software packages, the results of which are then verified. These results should be nearly identical, with only minor differences allowed.
By visiting the website of our organization, you can find information about the many projects developed by our engineers. The calculations are based on programs such as SCAD and RobotStructuralAnalysis. If there is a need to learn more complete list of our calculated refinery projects, you can obtain such information either by calling us or by visiting our company office.
The project documentation is delivered to the customer in printed form or in electronic form. The contract establishes the number of printed copies. The electronic format for saving information can be offered on Flash drives or CD disks - the option is negotiated in advance at the request of the customer.
Among the most commonly used types of project issuance are:
The electronic version of the transfer of the project must contain drawings, explications, as well as a 3D model of the refinery. When the customer has intentions to independently build an oil refinery, then NC files (LSTV) are issued to control machine tools with numerical control.
Control accompanies all stages of refinery design, without exception, to ensure the quality of documentation, the implementation of further manufacturing and installation processes. Our organization implements the following mandatory levels of control:
At the request of the customer, competent employees of our organization can perform many types of refinery quality control, such as non-destructive testing.
In the process of cooperation, an already created, finished project. Such solutions are systematized in our catalogues. Necessary amendments are made to each finished project according to the customer's requirements for the future refinery. The adjustment process seems to be not so laborious in comparison with the initial formation of project documentation and has a reduced time frame for the completion of all work. This type of cooperation between the customer and the contractor can also bring economic benefits, as it allows you to reduce financial costs by more than 50%.
The impressive volume of completed orders and developments in this area gave us the opportunity to compile a catalog of examples of refineries.
Typical designs can be classified into the following types:
If you have any difficulties with the choice of the type of construction, you can contact our staff. They will explain the pros and cons of each design type, lay out the details, and assist in choosing the option that will more closely match the request.
Since on the site we only list the main examples, classified according to the design specifics, the full scope of our projects can be found in the management department of our specialists. The refinery samples presented here are developed on the basis of advanced 3D modeling techniques.
Technologies for the design of metal structures are in constant development. We set ourselves the task of continuously improving the quality of refinery design, introducing all kinds of innovations into the work, and at the same time we strive to improve the methods and skills already mastered by our designers. Constant development is important for us, so studying developments from around the world and translating them into our production process is one of the main tasks. Our organization has established a learning process to expand the qualifications of personnel, study and implement world practice in the field of modernized developments. Operating with modern technological programs helps to achieve automation of the work cycle, and cuts off the increased labor intensity of the designer's work, which is associated with calculations of various types of statements and reporting.
Not so long ago, the execution of maps for cutting sheet and rolled profiles was carried out by hand, which assumed a high labor intensity of execution. Today, to facilitate this kind of work, automatic provision is used.
The process of assembling and installing a refinery is almost always a complex procedure. Our organization is ready to take on the responsibility of conducting architectural supervision, expertise and project support by specialized specialists for the entire period of construction. The service implies that the engineer responsible for the refinery project is personally present during the installation. The responsible person of architectural supervision carries out control operations that require the maintenance of a correct and consistent work schedule for the installation of the refinery. Estimated time spent by a representative at a given facility is 1-2 weeks. If there is an agreement with the client to establish a different time period, employees of the organization are at each stage, which offers a better guarantee of the quality of the product.
By concluding the contract, the parties immediately establish the criteria for payments, the period of work of field supervision specialists accompanying the project during construction.
The organization designs refineries, provides a full package of services, the final step of which is the commissioning of the finished product. Employees of our company in various specialized areas have extensive experience in implementing refinery projects. In order to warn against dubious related enterprises and save time, we recommend that you order design, manufacture and installation work in our organization. We have all the ingredients for this: modern machines, many implemented projects, a practical location of production - near Moscow.
The organization has at its disposal an installation department and teams of specialists in maintaining assembly work. Under the responsibility of the specialists of our organization lies the high quality of the work performed at any stage of the refinery manufacturing, the same applies to the construction object.
To carry out the tasks of designing a refinery, an enterprise must be part of an SRO - a self-regulatory organization. Our membership in the SRO has a term of more than six years. We provide the client with supporting documentation either through email, or the original in the office.
The preparation of project documentation developed outside the Russian Federation, and without complying with Russian standards and rules, is subject to a complex examination. Project documentation, formed by foreign specialists, requires redesigning. Everything must be adapted to the existing norms of the Russian Federation "from scratch": relevant documentation, calculations, drawings, calculation of loads on the entire structure of the refinery. These operations for processing the original documentation are design. The execution of the design takes a significant proportion of the time in comparison with the redesign, since the agreement and adoption of most of the design decisions and issues has already taken place.
The circumstance that causes the need for redesign is also the need to adapt part of the KM to the regulated parameters Russian legislation, since the original form may contain erroneous data on the tonnage of the structure and the adopted design solutions. In this case, redesign is an opportunity to reduce the mass of the structure and save financial costs.

The steam extinguishing system must be connected through two valves (or two valves) installed in series with a control tube with a valve installed between them.
8.41. To extinguish a fire in steam extinguishing systems, saturated, waste (crumpled) water vapor or superheated process steam can be used. At the same time, saturated steam is more effective for fire extinguishing than superheated steam.
8.42. Steam extinguishing can be carried out by means of stationary and semi-stationary systems (installations) of steam pipelines.
Stationary steam extinguishing systems include such systems of steam pipelines that supply steam directly to the protected object.

The steam pressure at the risers should be no more than 0.6 MPa (6 kgf / cm 2). Portable hoses can be used with 20 mm diameter watering stems or other nozzles.
The connection of hoses to the risers must be manual, without the use of tools, using a union nut with a handle or a "ruff".
8.45. Locking devices on steam lines for steam extinguishing (valves, gate valves) should be located in easily accessible places, outdoors, at a height of 1.35 m from the level of the site.
8.46. Perforated pipes are used as internal distribution steam pipelines for stationary steam extinguishing systems in enclosed spaces. Holes in perforated pipes for steam release should be 4-5 mm in diameter. To drain condensate from the supply steam pipelines and steam inlets, drains should be provided located in the lowest places along the slope of the pipes so that both condensate and steam jets do not interfere with the actions of maintenance personnel.
8.47. To supply steam to closed rooms, perforated pipes are laid along the entire inner perimeter of the room at a height of 0.2-0.3 m from the floor. In this case, the openings of the pipes are arranged so that the steam jets emerging from them are directed horizontally into the room.
8.48. When calculating steam extinguishing systems, the intensity of steam supply is taken as the main indicator. Estimated fire extinguishing time 3 min.
The intensity of steam supply is understood as the amount of steam supplied to enclosed spaces or tightly closed technological units per unit of time per unit volume filled with steam (kg / s * m 3).
The calculated intensity of steam supply (superheated and saturated) for volumetric steam extinguishing is given in Table. 8.
Table 8
_________
Note. For closed objects, their total internal volume is calculated.
8.49. Inert gases (nitrogen, carbon dioxide, argon, etc.) can be used to extinguish a fire both indoors and outdoors.
8.50. Extinguishing a fire (burning) with an inert gas is based on:
a) to reduce the concentration of oxygen in the air of industrial premises and around the place of combustion (stationary fire extinguishing systems);
b) on knocking down a flame of ignited gases and vapors with a jet of inert gas) in case of leakage through the leaks formed in apparatuses and pipelines (semi-stationary fire extinguishing systems).
8.51. In open installations, extinguishing with an inert gas is based on knocking down a flame of ignited gases and vapors with a jet of inert gas.

Introduction
General plan - a part of the project, which comprehensively addresses the issues of planning, placement of buildings and structures, transport communications and engineering networks on the territory of the refinery and petrochemical plant; the same part highlights the tasks associated with locating an enterprise in an industrial hub. The development of a master plan is a complex task that requires consideration of various factors.
Important design documents developed during the preparation of this part of the project are graphic images of the general and situational plans of the plant. The drawing of the layout of the territory allotted for the construction of the enterprise, on which all buildings and structures, roads and railways, underground and surface pipelines, cable lines for power supply and communications, etc., are applied during the design process, is called the master plan of the plant. The master plan is carried out on a scale that depends on the size of the structures being designed. General plans for refineries and petrochemical plants are usually developed on a scale of 1:500, 1:2000, 1:5000.
1. Placement of the plant. Situational plan
When designing new oil refineries and petrochemical plants, they should, as a rule, be located as part of a group of enterprises with common facilities (industrial hub), on the territory provided for by the district planning scheme or project, industrial area planning project.
Non-agricultural lands or unsuitable for agriculture are selected to locate the plant.
In the absence of such lands, plots on agricultural land of poorer quality are used.
Since refineries and petrochemical plants are sources of atmospheric air pollution, they should be located in relation to residential development, taking into account the prevailing winds.
Between the industrial zone and the residential area, a sanitary protection zone is provided, the dimensions of which are chosen in accordance with the "Sanitary - Design Standards for Industrial Enterprises".
During the site selection process, various options for plant location are plotted on the site plan drawing. In addition to the sites on the situational plan, industrial enterprises that are available in the area are plotted; existing settlements and the site planned for the location of the factory residential village; railroads and highways; routes of lines" of water supply and sewerage, indicating the places of water intake and sites for treatment facilities; factory CHPP and routes of power and heat supply lines; reservoirs and waterways; quarries of local building materials. The situational plan is drawn up on a scale of 1: 10,000 or 1: 25,000.
Rice. 1.1. Refinery situational plan
1 - the territory of the plant. 2 - administrative and economic zone; 3 - repair and mechanical base; 4 - equipment base; 5 - refinery expansion zone; 6 - treatment facilities; 7 - CHP; 8 - construction and installation site of the CHPP; 9 - commodity fleet of liquefied gases; 10 - railway station; 11- washing and steaming station; 12 - intake of drinking water; 13 - industrial water intake; 14 - oil receiving point; 15 - storage ponds of treated effluents.
On fig. 1.1 shows the situational plan of the refinery. Near the site of the refinery there is a plant thermal power plant, a territory is provided for the expansion of the plant. In accordance with the current fire safety standards, the commercial, liquefied gas base is removed from the main industrial site. The situational plan also shows an oil reception point, water intake facilities for drinking and industrial water supply, and a railway station. The settlement in this case is located at a distance of more than 5 km from the factory site and therefore is not shown on the plan.
2. Principles for constructing a master plan for refineries and petrochemical plants
When developing master plans for refineries and petrochemical plants, it is necessary to ensure the most favorable conditions for the production process, rational and economical use of land. The master plans of the refinery provide for: functional zoning of the territory, taking into account technological connections, sanitary and hygienic and fire safety requirements; rational engineering communications within the enterprise, as well as between the enterprise and the residential area; the possibility of building in stages or start-up complexes; protection of underground waters and open reservoirs from pollution by sewage and waste. The natural features of the construction area should also be taken into account (air temperature and prevailing wind direction, the possibility of large snow deposits, etc.).
An important indicator of the rationality of the decision of the master plan is the building density, which is the ratio of the building area to the area of the enterprise within the fence. The built-up area is defined as the sum of the areas occupied by buildings and structures of all types, including open technological, sanitary and energy installations, overpasses, platforms for loading and unloading devices, underground structures, warehouses. The head of SNiP P-89-80 "General plans for industrial enterprises" provides that the building density of refineries and petrochemical plants should be at least 46%. The placement of technological facilities on the master plan should correspond to the sequence of processing of raw materials in the process flow - from the main production (AT and AVT at the refinery, pyrolysis units at the petrochemical plant) to the facilities for the preparation and shipment of marketable products. Technological flows in the development of master plans are directed parallel to one another and perpendicular to the direction of development of the enterprise, which allows autonomous development of complexes under construction and in operation.
The master plan of the refinery and petrochemical plant should provide for the division of the territory of the enterprise into zones, taking into account the functional purpose of individual facilities. Zones are formed in such a way as to minimize oncoming flows, ensure compliance with safety standards and rules and industrial sanitation.
At modern refineries and petrochemical plants, the following zones are distinguished: pre-factory, production, utility, storage, raw materials and commodity parks.
In the pre-factory zone, a factory management, a training plant, a health center or a polyclinic, a general factory canteen, a fire station, a gas rescue station, etc. are located. The master plan of the pre-factory zone is shown in fig. 1.2. In the pre-factory zone, along with the solution of the general volumetric and spatial composition of buildings, additional elements of improvement should be provided. Separation of buildings in the pre-factory area is carried out according to functional features. The plant management is blocked with a machine counting station and automatic telephone exchange, a canteen - with a training center. The buildings of the fire station, gas rescue service, polyclinic, checkpoint are removed from the administrative block, as they are directly connected to the main transport highway going to the plant.
Fig 1.2. Master plan of the pre-factory area:
1- factory management with a conference room; 2.- machine counting station and automatic telephone exchange; 3 - dining room; 4 - training complex; 5 - polyclinic; 6 - checkpoint with a guardroom; 7 - fire station and gas rescue station; 8 - a canopy for bicycles; 9 - bus parking; 10 - parking for cars.
To create an original architectural solution, it is recommended to allocate separate volumes of buildings, and construct the plant management building with an increased number of storeys. On fig. Figure 1.3 shows the architectural design of the pre-factory area of one of the modern refineries.
The entrance points of enterprises should be located at a distance of no more than 1.5 km from one another, therefore, at the largest refineries and petrochemical plants, several pre-factory zones are provided, depending on the number of entrances and exits.
The production zone occupies 25-30% of the total area of the plant. It houses most of the enterprise's technological installations, off-site facilities (water recycling units, pumping stations for sewage systems, transformer substations, air and nitrogen compressors, flare facilities, a laboratory, etc.) .
Rice. 1.3. Architectural solution of the pre-factory zone of the refinery.
The main principles for constructing this zone are the flow of products, the location of objects, taking into account the prevailing wind direction, and the use of relief.
The utility zone is designed to accommodate mechanical repair, repair and construction, container shops and other buildings, as well as auxiliary production facilities. There may be several zones of ancillary facilities on the general plan of the refinery and petrochemical plant, since the placement of ancillary facilities depends on the attraction to certain other objects and zones. For example, garages, mechanical repair shops, which employ a large number of production personnel, gravitate towards the pre-factory zone, where urban passenger transport stops are located; amenity premises and catering facilities are located in separate zones, taking into account the radius of service.
In the storage area there are warehouses for equipment, lubricating oils, reagent facilities. This zone, for which objects require railways, also gravitates to industrial and auxiliary facilities that require rail transport: installations for the production of bitumen, sulfur, sulfuric acid, and a delayed coking unit.
In the zone of raw materials and commodity parks, tank farms of flammable and combustible liquids, pumping and railway racks are located, designed to receive raw materials and ship commercial products.
Areas that require rail transport (warehouse, raw materials and commodity parks) should be located closer to the periphery of the plant in order to reduce the number of railroad entries, reduce the length of tracks, and minimize the intersection of engineering networks and roads by railroads.
When placing energy-intensive facilities on the master plan, they should be brought as close as possible to the sources of steam supply (CHP, boiler houses) in order to reduce the length of the main steam pipelines.
The placement of technological installations on the master plan should ensure the flow of the process, minimize the length of technological communications, and exclude, if possible, oncoming flows. When developing the layout of technological installations, the equipment and intrashop pipelines are placed in such a way as to ensure the entry of raw materials and the exit of finished products from one side. When placing the installation on the general plan, they strive to ensure that the input of raw materials and the output of products are located on the side of the communication corridor.
The construction of refineries and petrochemical plants is carried out in complexes, which include one or more process units and off-site facilities. When laying out the master plan, one should strive to ensure that the facilities of one launch complex are located in the smallest number of blocks. It is necessary to place objects in quarters in such a way that the complex development of factory quarters is ensured and one does not have to repeatedly return to the construction of objects in previously built-up quarters.
When designing refineries and petrochemical plants, it is recommended to combine production, auxiliary and storage buildings into larger ones in all cases where such a combination is permissible according to technological, construction, sanitary and hygienic and fire safety standards.
The location of buildings and structures on the master plan should exclude the spread of harmful emissions, promote effective through ventilation of the industrial site and intershop spaces.
The territory of oil refineries and petrochemical enterprises during the design is divided by a grid of streets into quarters, which, as a rule, have a rectangular shape. The sizes of quarters are assigned depending on the dimensions of technological installations, however, the area of each quarter should not exceed 16 hectares. The length of one of the sides of the block should not be more than 300 m. The distance between objects located in neighboring blocks should be taken at least 40 m.
When designing, it is necessary to ensure good ventilation of the quarters, to avoid the construction of U-, W- and T-shaped buildings inside the quarters.
The width of the streets and driveways of the refinery and petrochemical plant is determined taking into account technological, transport, sanitary and fire safety requirements, the location of engineering networks and communications.
The sectional-block method of layout of the master plan used in the design of modern refineries and petrochemical plants provides for combining units into blocks, which carry out processes of the same name.
So, at two refineries, the construction of which was started in 1960-65, all primary distillation units are located in one line along the longitudinal axis and occupy a group of blocks located in the immediate vicinity of the enterprise fence. The next line of blocks is occupied by catalytic reformers, also located in neighboring blocks along the longitudinal axis. Next are the hydrotreatment units, the production of oils, sulfur. At another enterprise, the general plan "of which is shown in Fig. 6.4, two combined oil processing units of the LK-6u type are placed in one line along the longitudinal axis; in the next line there are secondary processing units, an automatic station for the preparation of marketable products, recycling water supply units and others facilities of the production zone In the eastern part of the plant, this zone is adjacent to the auxiliary and storage zones, in which the repair and mechanical shop, the equipment base of the directorate are located.The third and fourth lines are commodity and raw material parks.
Rice. 1.4. Refinery master plan:
1-combined oil refining units; 2-recycling installations 3-commodity parks; 4 - oil parks; 5-nodes of recycling water supply; 6 automatic mixing stations; 7 - repair and mechanical base; c - equipment base; 9-torch candles; 10- torch facilities; 11-railway loading racks; 12 - commodity pumping stations; 13 - fuel economy; 14 - reagent facilities; 15 - air compressor; 16 - plant management.
3. Engineering networks and technological pipelines
A significant number of technological pipelines and engineering networks (power lines, water supply and sewerage networks, automation and instrumentation cable networks) are being laid across the territory of refineries and petrochemical plants. When developing a master plan, the passage of engineering networks in the shortest direction and their separation according to their purpose and methods of laying should be ensured.
Technological pipelines and engineering networks are placed in the strip located between the intra-factory roads and the boundaries of the installations, as well as in the corridors within the quarters.
As already mentioned, there are various ways of laying communications: underground, ground in a tray, ground on sleepers, overpass.
When laying pipelines on overpasses, the project must provide for the possibility of placing additional pipelines on the structures of overpasses, which will appear during the expansion of enterprises and the construction of subsequent stages. In order to save space, the main overpasses of land pipelines in the production area are designed as multi-tiered ones, taking into account the possibility of their subsequent use.
When laying networks on low supports, pipelines are combined into bundles with a width of no more than 15 m. If a crane installed on a highway is used to repair pipelines, then the specific width of the pipeline bundle is determined by the length of the crane boom. In cases where networks on low supports are located outside the access zone of a crane moving along a road, a free lane 4.5 m wide along the pipeline bundle is provided for the movement of truck cranes and fire trucks. Special reinforced concrete bridges are designed to cross technological pipelines placed on low supports with intra-factory roads. The width of the strip in which the pipelines are placed on low supports should allow the laying of additional pipelines when the plant is expanded.
For laying electrical cables from power sources (CHP, main step-down substation) to consumers, independent cable racks with walk-through service bridges are designed. Cable racks are placed along the roads from the side opposite to the side of laying the racks of technological pipelines. At the intersection of electrical cable racks with ground pipelines of oil and oil products, electrical cable racks are placed below the process pipelines and provide a blank fire-resistant coating at the intersection that protects the electrical cables.
The combination of cable racks with process pipeline racks is considered acceptable if the number of cables does not exceed 30.
Underground networks and communications are laid, if possible, in one trench, taking into account the timing of commissioning of each network and the standard distances between pipelines.
4. Vertical layout. Drainage from the site
The task of the vertical planning of the territory of the enterprise is to bring the relief of the site in line with the project, taking into account the high-rise placement of buildings and structures.
Vertical layout solves various technological and construction problems: ensuring such a high-altitude location of buildings and structures that creates the best transport conditions; creation of conditions for the rapid collection and removal of atmospheric water from the site; organization of relief and sewerage systems, ensuring the rapid removal and collection of spilled oil products to the safest places, as well as the rapid removal of water used for fire extinguishing. The following vertical planning systems are used: solid, selective, mixed or zonal. With a continuous system, planning work is carried out throughout the entire territory of the enterprise; with a selective system, planning is provided only for those areas where buildings and structures are located.
With a mixed planning system, part of the plant's territory is planned selectively, and part is planned according to a continuous planning system.
The current regulations provide that at enterprises with a building density of more than 25%, as well as with a high saturation of the industrial site with roads and engineering networks, a system of continuous vertical planning should be used. Guided by this requirement, at modern refineries and petrochemical plants, instead of the previously common mixed system, they usually use a continuous vertical layout. Previously, it was considered that the most economical is the development of a vertical layout with a full balance of cuts and fills for the plant. Experience has shown that often, according to the conditions of construction, the work on the construction of individual embankments and excavations does not coincide; the desire to balance the volume of earthworks in a number of cases led to an unreasonable increase in the height of the foundations for structures, a deterioration in the conditions for laying networks.
The main criteria for the rationality of vertical planning are currently considered to be: ensuring the convenience of technological connections, improving the conditions for construction and laying the foundation.
The following slopes of the surface of the site, plant are accepted: for clay soils: 0.003 - 0.05; For sandy soils: 0.03; For easily eroded soils: 0.01; For permafrost soils: 0.03.
Tank farms and free-standing tanks with flammable and combustible liquids, liquefied gases and toxic substances are usually located at lower elevations in relation to buildings and structures. In accordance with the requirements of fire safety standards, these tanks are surrounded by earthen ramparts or fireproof walls.
When designing the vertical layout of the site, it is necessary to ensure that the floor level of the first floor of buildings is at least 15 cm higher than the planning level of the areas adjacent to the building.
A mixed system of open storm drains (trays, ditches, drainage ditches) and closed industrial sewerage is used to drain surface water and oil spills. Closed sewage is used in areas of increased fire danger of oil refineries and petrochemical industries. Surface water (rain and melt) from the territory of enterprises is directed to storage ponds.
5. Transport systems
When developing a draft master plan for an industrial site, issues of external and internal transport are worked out in detail. The external transport of refineries and petrochemical plants are railway and car roads, linking enterprises with public transport routes; internal transport includes transport devices located on the territory of the plant.
A feature of refineries and petrochemical plants is the complete absence of in-plant rail transportation. Railway tracks are used only for the shipment of finished products and the receipt of reagents, containers, and in some cases - raw materials. Therefore, the network of railways on the territory of enterprises is concentrated, if possible, by grouping objects that are serviced by the railway on the general plan.
In order to create conditions without reloading access to the all-Union railway network, the railway tracks of the refinery and petrochemical plant are designed with a gauge of 1520 mm (normal gauge). The design of internal railway transport at refineries and petrochemical plants is carried out on the basis of SNiP II-46-75 "Industrial Transport".
Intra-factory roads, depending on the purpose, are divided into main, industrial, driveways and entrances. Trunk roads provide passage for all types of vehicles and unite all intra-factory roads into a common system. The parameters of main roads (width of the carriageway and roadsides, pavement design, turning radii, etc.) should ensure the passage of assembly cranes and mechanisms, the transportation of large and heavy vehicles and structures.
Production roads serve to connect workshops, installations, warehouses and other facilities of the enterprise between themselves and the main roads. The main production and construction cargoes are transported along these roads. Driveways and entrances provide for the transportation of auxiliary and household goods, the passage of fire trucks.
The number of traffic lanes, the width of the carriageway and the roadsides of the subgrade is selected in accordance with the purpose of the roads and the traffic density. The highest traffic intensity per one lane of the carriageway of intra-factory roads should not exceed 250 vehicles per hour. As a rule, roads are provided with one common carriageway.
Intra-factory roads are designed, as a rule, as straight lines, the scheme of roads at the plant can be ring, dead-end or mixed.
The distance from the intra-factory road or passage to structures and buildings in which production of categories A, B, C and E is located must be at least 5 m. .
At refineries and petrochemical plants, as a rule, suburban roads are built, their subgrade raised above the adjacent territory and serves as a second embankment in the area of the commodity base. It is advisable that the planning marks of the carriageway of motorways be at least 0.3 m higher than the planning marks of the adjacent territory.
When choosing the type of pavement, one should be guided by the conditions of the construction period - use reliable types of capital pavements.
6. Landscaping and landscaping of the industrial site
The task of improving the industrial site of refineries and petrochemical plants is to create working conditions that reduce the impact of harmful substances, giving the enterprise a neat appearance. Improvement elements include sidewalks, green spaces, small-form architecture.
Sidewalks are provided along all main and industrial roads, regardless of the intensity of pedestrian traffic. Sidewalks along driveways and entrances should be designed only in cases where the traffic intensity exceeds 100 people per shift. The width of the sidewalk depends on the amount of foot traffic. With a traffic intensity of less than 100 people per hour in both directions, the width of the sidewalk is assumed to be 1 m: At higher intensity, the number of lanes along the sidewalk is determined at the rate of 750 people per shift per lane and then the sidewalk is designed from several lanes 75 cm wide each.
The sidewalk located next to the road must be separated from it by a dividing strip 80 cm wide.
Crossing of mass passage routes working with the railway should be avoided. In the event of such intersections, crossings in the same level must be equipped with sound signaling traffic lights.
The area of plots intended for landscaping within the fence of the enterprise is determined at the rate of at least 3 m2 per one worker in the most numerous shift. The maximum size of plots intended for landscaping, however, should not exceed 15% of the site of the enterprise.
It is recommended to use deciduous trees and shrubs that are resistant to harmful emissions for landscaping the territory of refineries and petrochemical plants. Do not use in landscaping trees that emit flakes, fibrous substances and pubescent seeds during flowering.
The distance from buildings and structures to green spaces should be at least 5 m, unless the conditions for the protection of enterprises require a greater distance from the fence.
For recreation and gymnastic exercises of workers on the territories of the refinery and petrochemical plant, landscaped areas are provided, the size of which is determined at the rate of not more than 1 m2 per employee in the most numerous shift.
It is recommended to protect administrative and economic facilities located in the pre-factory zone from the harmful effects of vapors, gases, dust with a strip of green spaces.
7. Enterprise security
The task of protecting refineries and petrochemical plants is to prevent unauthorized persons from entering the territory of the enterprise, control the entry and exit of vehicles, the import and export of materials, equipment, products, etc.
The territory of the refinery and petrochemical plant is surrounded by a fence made of fireproof materials. For the passage of people, checkpoints are set up, and for the passage of railway and road transport - travel points equipped with mechanically opening gates with remote control. Checkpoints are set up at the checkpoints.
Between the fence and intra-factory facilities (installations, buildings and structures, embankments of tank farms), a free area should be provided to ensure the free passage of fire trucks and the creation of a security zone; The width of this zone must be at least 10 m.
Reliability of the enterprise security is ensured by security lighting, designed to create the necessary illumination of the approaches to the plant. Simultaneously with the installation of a fence around the perimeter of the refinery and petrochemical plant, it is necessary to provide a security alarm. The use of burglar alarms ensures constant automatic monitoring of protected objects, alarm signals to the security point indicating the places of violation.
8. Title list of enterprise objects
Simultaneously with the master plan, a title list of refinery and petrochemical facilities is compiled. The title list lists all the buildings and structures of the enterprise, on-site and off-site networks, indicates the quarters in which the installations and workshops are located, and off-site facilities. If the construction of the plant is carried out in stages, then it is advisable to indicate which stage of construction the object belongs to. For the convenience of using the master plan and the title list, it is recommended to assign numerical designations to all plant facilities, including networks. It is desirable that the indexing of objects reflects the belonging of a given object to a particular group (installations, general factory facilities). The title list is compiled at the initial stage of plant design and then adjusted during the development of expansion and reconstruction projects of the enterprise.
