Description

The invention relates to the industrial processing of oil and gas condensates, taking into account the specifics of the economy in the northern regions and can be used in the oil refining industry.

The structure of oil refineries has been known for a long time and includes in general the following set of units: electro-desalination units for preliminary oil treatment (ELOU), units for primary oil refining (atmospheric tubules (AT) and atmospheric vacuum tubes (AVT)), gas fractionation plants, and oil product reforming plants (platforming), thermal cracking units, catalytic cracking units, hydrocracking units, visbreaking units, hydrotreating units, units toric distillation of petroleum products, isomerization units, alkylation units, dewaxing units, deasphalting units, bituminous plants, heavy residue coking units, acid gas absorption treatment plants, adsorption treatment and drying of process streams, thermal and catalytic waste gas treatment plants, wastewater treatment plants and etc.; a particular refinery design is usually tied to the quality of the source oil and the range of products produced. The optimal level of the technological structure of oil refining production requires the formation of a set of technological processes that is determined by modern requirements of the oil product market in combination with advances in technology and technology for oil refining.

A well-known oil refinery, including a tank farm for receiving and storing crude oil, a technological complex of units for refining and separating oil into fractions, obtaining commercial petroleum products with possible at least partial compounding, auxiliary units and units, at least one disposal system combustible waste and tank farm for storing separated fractions and commercial oil products (patent for invention RU 2347800 C1, IPC C10G 9/00, F16L 55/00, filed August 15, 2007, published February 2, 2009 ).. The main disadvantage of this invention is the lack of concretization of a set of process plants and, as a consequence, the uncertainty of the range of commercial petroleum products.

There is also a known scheme of oil refining production with a separation unit for the preparation and processing of oil, including heavy oil, residues of oil refining and petrochemical industries and other liquid organic media, including desalination and dehydration processes, as well as fractionation and production of commercial products, while in the production scheme before the fractionation unit (before supplying to atmospheric or atmospheric vacuum tube), or after it, include a separation unit in which the initial cheese it is divided into two parts: the heavy part of the separation is high molecular weight high boiling fractions containing mainly products with a boiling point of 340-380 ° C and above, in which the bulk of the harmful components and impurities of the feedstock are concentrated, which are then used to prepare heavy commercial products of the type bitumen, pitch, coke, boiler fuel, etc., and the light part of the separation of raw materials, enriched in the target fuel fractions and depleted in harmful impurities, which is sent to the subsequent transfer work to obtain light petroleum products (gasoline, kerosene, diesel fuel), and to increase the processing depth in the separation unit, the process of cracking the feedstock is carried out (utility model patent RU 69064 U1, IPC C10G 7/00, C10G 9/36, filed on 28.04. 2007, published December 10, 2007). The main disadvantage of this invention is the presence of a separation unit in which the feedstock is divided into two parts: the heavy part of the separation with a boiling point of 340-380 ° C and above and the light part of the separation of the raw material enriched in the target fuel fractions, since:

- if the separation unit provides only a single evaporation of the original oil, the quality of separation into two types of raw materials will be extremely low and the bulk of the light part of the feed (mainly diesel and kerosene components) will go into the heavy part and a significant amount of heavy, mainly oil components will go into the light part, which will entail a deterioration in the operation of subsequent technological installations;

- if the separation unit provides fractionation of raw materials on contact devices, the quality of separation into two types of raw materials will be more efficient, but the separation of the light part of the raw materials at AT or ABT installations becomes ineffective and requires a complete reconstruction of these plants with a change in the technological mode of their operation;

- for the operation of a gas fractionating unit with an amine gas purification unit of the separation unit, it is necessary to preheat the feedstock to a temperature of about 340-380 ° C and with further cooling of the light and heavy parts of the feedstock, it will lead to an increase in the energy consumption of production by about 30-40% compared with the energy intensity of the plants AT or ABT.

The Khabarovsk oil refinery is also known, including the ELOU-AT and ELOU-AVT units, a gas fractionating unit with an amine acid gas purification unit, followed by hydrogen sulfide processing at the Claus sulfur recovery unit, a reforming, isomerization and hydrotreating unit, a hydrocracking and visbreaking unit, an installation hydrogen production, bitumen installation and fleet of commercial products (Schematic diagram of material flows at Khabarovsk Oil Refinery OJSC. Information is presented in electronic form m view on the website http://khab-npz.ru/shema). The disadvantage of this scheme is the strict assignment of the plant in the processing of a certain type of oil, the transition to another type of oil is associated with a significant change in production technology and the development of non-standard products during the transition period. In addition, the transfer of marketable fuel products (gasoline, diesel fuel, fuel oil, marine fuel) from Khabarovsk to the northern regions with poorly developed infrastructure and the frequency of fuel delivery along rivers in a short shipping period and through winter routes significantly increases the cost of fuel, which leads to an indirect cost increase all components of the industrial and housing sector of the northern regions. For example, when transporting automobile fuel from Khabarovsk to Yakutsk over a distance of 2500 km using a KAMAZ 43118 car with a carrying capacity of 7 tons, about 2 tons of transported fuel will be spent on the actual transportation of fuel and a return flight.

There is a known scheme of an oil refinery for the processing of gas condensate with a sulfur content of not more than 400 ppm with the production of commercial products in accordance with the EURO-5 standards (class 5 according to the Technical Regulations), which includes the following units: a fractionation unit for raw materials, a hydrotreatment unit for fraction N. -360 ° C, a unit for rectification of hydrotreating products into fractions for further processing, a unit for hydroisomerization of light gasoline, a unit for rectification of a hydroisomerizate and a unit for compounding commercial products, and a scheme of an oil refinery for deep oil processing with the production of commercial products in accordance with EURO-5 standards ( class 5 according to the Technical Regulations), which includes the following units: ELOU and atmospheric-vacuum distillation unit, gasoline hydrotreatment unit, hydro-unit the source and hydrodeparaffinization of the diesel fraction, a diesel compounding unit, a gasoline compounding unit, an isomerization and hydroisomerization unit, an amine gas purification unit using monoethanolamine as an absorbent, a Claus process for the production of elemental sulfur, tar gas oxidation plant, a hydrogen gas unit installation of vacuum gas oil hydrocracking (Installation for the processing of gas condensate (oil). Information is presented in electronic form on the website http://additive.spb.ru/upgk.html. The disadvantage of these schemes of oil refineries is the narrow raw material orientation of enterprises: having significantly different sets of process plants, only a certain type of hydrocarbon raw material is processed - either oil or gas condensate.

There is a well-known project for the processing of gas condensate in the Kamchatka Territory with a production volume of about 240.0 thousand tons until 2023 to produce gasoline, kerosene and diesel fractions using a modular unit type UPNG-40 with a single module capacity of up to 40.0 thousand t / year. The processing of gas condensate in a block-modular installation will make it possible to obtain about 92.7 thousand tons of straight-run gasoline fractions of about 144.8 thousand tons of diesel fuel until 2023 after the construction of the installation in 2015. Estimated project cost: 180 million rubles (Processing gas condensate in the Kamchatka Territory. Information is presented in electronic form on the website http://www.australia.mid.ru/invest_kamchatka_02.pdf). The disadvantages of this project are:

- high costs of fixed assets of low-productivity installation;

- low quality of the produced straight-run gasoline fractions and diesel fuel due to the limited number of blocks in the module;

- the absence of consumers of gas fractions isolated from gas condensate will lead to their burning in flares with environmental pollution;

- It is not known what are the prospects for using heavy residues of gas condensate after the selection of fuel fractions.

The processing of hydrocarbons in the northern regions has significant differences from similar processes in the central regions of the Russian Federation or in the Far East. Firstly, in the northern regions, characterized by an imperfect infrastructure, numerous hydrocarbon deposits are concentrated - oil of various nature, a variety of gas condensate fields, which sets the task of processing hydrocarbon raw materials substantially unsteady in composition during the operation of the plant. Secondly, the specifics of the region require the development in place of a specific range of products, in particular winter and Arctic diesel fuel. Thirdly, the demands of marketing are forcing the owners of the hydrocarbon processing plant to look for new, cheaper sources of raw materials, which often differ in composition from previously used ones. Fourth, the construction and operation of mini-refineries at each field is less economically efficient than the formation of a large enterprise that processes raw materials throughout the region. Fifthly, the transition of a plant from one type of raw material to another, for example, from oil to gas condensate, requires preliminary study of the technology and the formation of a new field of technological parameters for the operation of plants, which often leads to a deterioration in the quality of the final commercial products.

When creating the invention, the task was to develop a highly efficient plant for the processing of hydrocarbon raw materials in the northern regions, which allows working on raw materials of various nature, in particular oil, gas condensates and their mixtures, with the possibility of an easily realizable transition from one type of raw material to another, developing an assortment of marketable products, necessary directly in the northern regions, and an increased level of environmental safety. With a sufficiently high capacity of the plant, which processes a wide range of hydrocarbon raw materials, it is possible to further increase the efficiency of the use of fixed assets of the enterprise and reduce the need for scarce highly qualified personnel in areas with demographic insufficiency.

The problem is solved due to the fact that the hydrocarbon processing plant in the northern regions, containing a feed tank farm, a stabilization unit for the initial hydrocarbon feed with a stabilization gas separation, an atmospheric distillation unit for the stable hydrocarbon feed with the release of hydrocarbon gas, gasoline fraction, diesel fraction fuel and fuel oil, a gas fractionation unit for hydrocarbon gas extracted from an atmospheric distillation unit and an initial stabilization unit hydrocarbon feedstock, with separation into deethanization gas, a liquefied technical mixture of propane and butane, propane and butane, an isomerization unit for the gasoline fraction extracted from the atmospheric distillation unit, a gasoline hydrotreatment unit, a reforming unit to produce high-octane gasolines, a hydrotreatment and dewaxing unit for the diesel fuel fraction, allocated to the installation of atmospheric distillation of hydrocarbons, the installation of sanitary cleaning from acid gases, a grocery tank farm and a pipeline system The odoids linking the technological units to each other and the tank farms additionally includes a compounding unit for various hydrocarbon feed streams; the sanitary treatment unit uses water as an acid gas absorber with subsequent disposal of effluents into absorbing wells for injection into the reservoir, the fraction fraction and ballast fractions of the atmospheric unit distillation (that is, fractions that do not have further use as commercial products) and part of the stabilized source with Darya fed to the compounding unit to obtain commercial products shipped commercial oil, diesel oil dewaxing installation ensures the production of diesel fuel or winter, or the Arctic. The inclusion of the compounding unit in the plant’s scheme at the initial stage of production allows us to form the optimal hydrocarbon feedstock for the plant as a whole when various quality hydrocarbon feedstocks enter the feed tank farm. The use of acid gas as a absorbent in a sanitary installation avoids the inclusion of an energy-intensive stripper, which is usually used when using acidic absorbent as a special absorbent gas, using special expensive reagents, for example, various amines for absorbent regeneration and, in addition, requires additional inclusion into the plant’s plant scheme for the utilization of acidic components released from the absorbent during its regeneration (primarily hydrogen sulfide, mercaptan, dioxi and carbon), and due to the final circuit substantial simplification of the plant to reduce the basic foundations of the enterprise. Acidic water generated in the absorber of the acid gas sanitary treatment facility is pumped through the wells into the formation, participating in the formation of the formation watering circuit. The heavy residues from the bottom of the distillation column of the hydrocracking unit are pumped into stable gas condensate to produce, after mixing, the required proportion of marketable oil, which is pumped further through the pipeline to consumers in the central part of the country. The diesel dewaxing unit ensures the formation of an optimal range of diesel fuel for the northern regions: either winter or Arctic diesel, depending on the time of year.

It is advisable to use either unstable low-sulfur gas condensate, or unstable light low-sulfur oil, or stable light low-sulfur oil as hydrocarbon raw materials in the northern regions, which expands the range of processed raw materials.

It is also advisable to use a mixture of unstable condensate and stable and / or unstable oil as hydrocarbon raw materials, which will reduce the amplitude of fluctuations in the composition of the initial processed hydrocarbon raw materials and significantly stabilize the operation of the plant as a whole.

It is also advisable that part of the stabilized hydrocarbon feedstock is shipped as a commercial product (commercial oil), and the remaining part is processed at an atmospheric distillation unit.

It is advisable that during the processing of unstable hydrocarbons, its stabilization and atmospheric distillation should be carried out on a single installation.

It is advisable that the plant’s scheme include a fuel oil hydrocracking unit for processing the residue of atmospheric distillation and an accompanying hydrogen production unit with the production of diesel fuel, gasoline and hydrocarbon gases, while the gasoline fractions and the unconverted residue of the hydrocracking unit are pumped into stabilized raw materials shipped as commercial oil, which allows you to maintain the range of fuel products in accordance with the needs of the respective region.

It is advisable that the gasoline fractions of the atmospheric distillation unit or the ballast fractions of atmospheric distillation and isomerization be partially or fully pumped into an additional commercial product corresponding to the pyrolysis (naphtha) feed.

It is advisable that partially or in full gasoline fractions of hydrocracking and atmospheric distillation units are compounded in raw materials for pyrolysis.

It is also advisable that the gaseous hydrocarbon hydrocracking products enter the gas fractionation unit of the hydrocarbon gas mixed with the gases of the atmospheric distillation unit.

It is also advisable that at the design stage of a hydrocarbon processing plant, individual processing units, depending on the range of variable characteristics of hydrocarbon raw materials and incoming processing products, are calculated according to parameters corresponding to the lower or upper boundary of the range of variable characteristics, which ensures extremely efficient operation of the installation.

Example 1. A hydrocarbon processing plant in the northern regions with a feedstock capacity of 2 million tons / year is located in the region where three types of gas condensate are produced (table 1) and two types of oil (table 2), while gas condensate No. 1 is characterized the presence of almost only gasoline fractions, gas condensate No. 2 is characterized by the presence of fractions of gasoline and diesel fuels, gas condensate No. 3 is characterized by the presence of diesel fractions with an insignificant admixture of heavy (fuel oil) fractions, oil No. 1 contains t about 50% fuel oil fractions and a substantial amount of gaseous impurities №2 oil contains more than 50% fuel oil fraction and a minor amount of gaseous impurities.

Due to the fact that a hydrocarbon processing plant located in a given region can function at different periods depending on the marketing situation both in terms of the cost of hydrocarbon raw materials and the range of products produced, it should provide optimal conditions for processing raw materials in combination with a flexible scheme processing already at the design stage of the plant for its individual technological units, depending on the range of varied characteristics of hydrocarbons, and The initial processing products were calculated according to the parameters corresponding to the lower or upper boundary of the range of varied characteristics of the starting products (raw materials) of the processing, which ensures extremely efficient operation of the installation. The potential productivity of some plants and the rationale for their performance when using various sources of hydrocarbon raw materials in the region as plant raw materials are given in table 3.

Example 2. A hydrocarbon processing plant in the northern regions with a feedstock capacity of 2 million tons / year receives oil No. 2 with a low content of gas components; this allows to increase the plant’s raw material productivity up to 3 million tons / year to ensure the effective operation of the oil stabilization unit, after which 1 million tons / year of stabilized oil is sent to the compounding plant for commercial products, where gasoline fractions and unreformed unit residue are added to the stabilized oil hydrocracking with further shipment of the compound as a commercial oil.

Example 3. A hydrocarbon processing plant in the northern regions with a feedstock capacity of 2 million tons / year is supplied with oil and gas condensates, which, after compounding, form the hydrocarbon processing feedstock that does not correspond to the data in Tables 2 and 3 and that have an intermediate fractional composition. In this case, specific technological units designed according to the parameters corresponding to the lower or upper boundary of the range of varied characteristics of the initial products (raw materials) of processing can work under the following technological operating conditions:

- increase the productivity of the installation in excess of the design while maintaining the quality of the final products;

- maintaining the design productivity of the installation while improving the quality of the final products;

- putting the unit into circulation mode with mixing of the final products and returning them to the input as feedstock while minimizing energy costs.

Thus, the hydrocarbon processing plant declared as an invention in the northern regions can function at different periods of activity depending on the marketing situation, both in terms of the cost of hydrocarbon raw materials and the range of products produced, providing optimal conditions for the processing of raw materials in combination with a flexible scheme processing.
