Gas processing

AO "Dagneftegaz" Refinery processes a range of gas such as dry gas, wet gas, shale gas, stripped gas, liquefied natural gas and marketable gas at the company’s gas processing plant located at the Eastern part of Siberia, Russia.

General information

The Company’s Gas Processing Plant became a part of the enterprise in 2010, and a freight fleet was built with a loading rack for shipping a wide fraction of light hydrocarbons and stable gas for subsequent shipment to consumers in railway tanks.

The gas plant’s finished products have always been in high demand on the market, not only in Russia and the CIS markets, but also beyond its borders. Over the years, liquefied gases were sent to consumers from different regions of the country and shipped for export.

Plant modernization

After the Gas Processing Plant acquisition, the company, immediately carried out a reconstruction program of the facility, the annual volume of natural gas received for processing was increased from 2 to 3.6 billion cubic meters. In 2018, a number of approved projects were implemented at the Gas Processing Plant, aimed at improving the level of industrial safety standards.

The reconstruction of the fire extinguishing system in the gas processing workshop was completed. As a result of the processing of associated petroleum gas, AO "Dagneftegaz" Refinery produces dry stripped gas, a wide fraction of light hydrocarbons, stable gasoline and technical propane.

A new custom furnace was built, 5 times more economical than the previous one, which saved up to 11 million m3 of gas per year. Also, pumping equipment and heat exchange equipment were upgraded. The two-year reconstruction of the reverse water supply cooling tower was completed, which made it possible to reduce annual water losses by 65 thousand m3 . The selection of target components from gas increased by 19%.

In 2019, the flare was reconstructed with the separation of the flare systems of the plant and the commodity and raw material storage. This increased the safety of production and allowed to bring the plant facilities to the required norms and rules.

In the same year, the company built its own desulphurization unit with a capacity of 220 million m3 of gas per year. It included blocks of nitrogen production and air conditioning instrumentation. A “Program of measures for the technical re-equipment of plant facilities” was developed and approved.
