Oil and Gas processing

GAS PROCESSING

THE STRUCTURE OF THE COMPANY INCLUDES A HIGHLY TECHNOLOGICAL COMPLEX FOR THE PREPARATION, STORAGE, AND PROCESSING OF ASSOCIATED PETROLEUM GAS, A WIDE FRACTION OF LIGHT HYDROCARBONS, AND THE SHIPMENT OF PROCESSED PRODUCTS.

ASSOCIATED PETROLEUM GAS IS A VALUABLE RAW MATERIAL FOR THE PRODUCTION OF A WIDE RANGE OF GAS-PROCESSING PRODUCTS OF THE HIGHEST QUALITY, WHICH IS FURTHER USED IN PETROCHEMICALS AND POWER ENGINEERING. PRODUCTS ARE IN DEMAND ON THE DOMESTIC MARKET, IN THE CIS MEMBER-STATES AND NON–CIS COUNTRIES.

PRODUCTION OF GAS PRODUCTS, MILLION TONNES

The structure of the Company includes a highly technological complex for the preparation, storage, and processing of associated petroleum gas, a wide fraction of light hydrocarbons, and the shipment of processed products.

The complex for gas-processing production consists of units for hydrogen sulfide removal, compression of oil and dry stripped gas, a cryogenic unit for deep processing of dry stripped gas, gas cleaning and drying facilities, low-temperature condensation and rectification, cascade refrigeration unit, gas fractionation units, flare facilities, a warehouse park for the reception and storage of raw materials and finished products, a loading and unloading overpass for sending products by rail.

At present, the following range of high-quality products is being produced, including the «A» and «Highest» brands:

  1. Natural combustible gas supplied and transported by main gas pipelines (STO Gazprom 089-2010).
  2. Hydrocarbon liquefied fuel gas for utility consumption (GOST 20448-90) is produced in three brands: PT = propane technical, MPBT = mixture of propane and butane technical, BT = butane technical. Depending on the brand, the content of propane is 75%–40%; the rest is butane. It is used as a fuel for utility consumption and industrial purposes. It is produced by mixing fractions of propane and butanes in the ratios established for the respective brands.
  3. Hydrocarbon liquefied fuel gases, GOST R 52087-2003 used as fuel for utility consumption, motor fuel for road transport, and for industrial purposes are produced in five brands: PT = propane technical, PA = propane automobile, PBA = propane-butane automobile, PBT = propane-butane technical, BT = butane technical.

It is produced by mixing fractions of propane and butanes in the ratios established for the respective brands. .

  • Natural combustible gas supplied and transported by main gas pipelines, STO Gazprom 089-2010. It consists mainly of methane with a small amount of ethane and propane. The lowest heat of combustion must be at least 7,600 kcal/m3, the concentration of hydrogen sulfide is not more than 0.02 g/m3. It is produced from petroleum gas by the method of stripping (removal of heavy components—liquid hydrocarbons—from petroleum gas).
  • Technical sulfur, GOST 127.1-93, is used for the production of sulfuric acid, carbon disulfide, rubber products, in the pulp and paper, textile industries, and in agriculture. It is produced from hydrogen sulfide during the purification of petroleum gas by the Klaus method.
  • Technical oxygen gas, GOST 5583-78, is used for gas-plasma processing of metals and other technical purposes. It is produced from atmospheric air by the method of low-temperature rectification after preliminary cleaning, drying, compression, and cooling of the air.
  • Nitrogen gas, GOST 9293-74, is used to create an inert atmosphere for the production, storage, and transportation of easily oxidized products, for high-temperature metal processing, for the preservation of closed metal vessels and pipelines, and other purposes (for displacing gases from apparatuses and pipelines).
  • It is produced from atmospheric air by deep cooling and separation after preliminary drying, cleaning, and compression of the air.
STRATEGIC DEVELOPMENT OBJECTIVES ARE IMPROVEMENT AND MODERNIZATION OF THE TECHNOLOGICAL CAPACITIES OF THE GAS-PROCESSING PLANT to increase the competitiveness of deep processing of hydrocarbon raw materials, for obtaining products with high added value.
