FIELD: gas industry.SUBSTANCE: invention relates to the field of operation of gas distribution stations of gas trunk-lines (hereinafter-GDS), in particular, purging of gas purification units (hereinafter - GPU). The technical result is efficient use of the resource through natural gas conservation, which, instead of being released into the atmosphere, it is fed into the output pipeline of the GDS after additional purification. The technical result is achieved by the fact that the gas ejection unit is additionally mounted at the GDS. The ejection line with a small cleaning filter, pressure gauges and a valve is connected to the equalization pipeline after its valve. A line of active gas with valves is cut in after the output valves of the GPU up to the input valves of the pressure regulators. The output line with the output valve is connected to the equalizing pipeline between the place of its insertion into the output pipeline of the gas distribution station and the bypass valve of the ejection unit connected to the ejection line between the small purification filter and its valve. The high-pressure blown gas is bypassed from the GPU through the drainage pipeline to an enclosed condensate trap. Gas from the condensate trap is fed through the equalizing pipeline to the low-pressure GDS output pipeline. After reaching the pressure in the condensate collector equal to the pressure in the output pipeline of the GDS, and the gas remaining in the condensate collector is ejected into the output pipeline of the GDS.EFFECT: efficient use of the resource through natural gas conservation, which, instead of being released into the atmosphere, is fed into the outlet pipeline of the GDS after additional purification.1 cl, 1 dwg

Method of no-waste purging of gas purification units

FIELD: gas industrySUBSTANCE: invention relates to the field of gas industry, in particular to objects of the main gas pipeline, and can be used to reduce natural gas losses during operation of the condensate collection unit of the process gas purification system of a compressor station In the current scheme of the condensate collection unit of the process gas purification system of the compressor station, which includes two technologically interconnected underground tanks, tied with pipeline fittings using high and low pressure pipelines, according to the invention, a high pressure gas outlet pipe is installed with pipeline and shut-off and control valves between the purge gas pipeline of the first underground condensate collection tank and the inlet gas pipeline to the fuel and start-up gas unit; low pressure gas outlet pipe was installed with pipeline and shut-off and control valves between the purge gas pipeline of the second underground condensate collection tank and the inlet gas pipeline to the gas heater burner unit; tap is installed with shut-off and control valves between the low-pressure gas pipeline and the low-pressure gas burner unit and the inlet gas pipeline to the hot-water boiler burners unit of the backup boiler houseEFFECT: object of the invention is resource saving due to the economy of natural gas, which instead of being vented to the atmosphere from two underground condensate collection tanks, technologically interconnected, is used to supply high-pressure gas as an input gas to the fuel and start-up gas unit for its own technological needs of the compressor shop and as low-pressure fuel gas for gas heater burner units and hot water boilers of the backup boiler compressor station1 cl, 1 dwg, 3 tbl

Condensate collection unit of process gas purification system of compressor station

FIELD: oil and gas industry.SUBSTANCE: invention relates to the field of the gas industry, in particular to the objects of the main gas pipeline, and can be used in the operation of the compressor station. Method of the air-cooling apparatus cleaning of natural gas at the compressor station is that for connecting the air-cooling apparatus of the gas to the intake manifolds and the gas outlet, two sections of metal gas pipelines between the inlet ball valve and the gas air-cooling unit are dismantled, and also between the gas air-cooling unit and the outlet ball valve; installation of two flexible high pressure hoses by means of four flange connections, two pressure gauges at the inlet and outlet of the gas air-cooling device, allowing to estimate the degree of contamination, deterioration of heat removal and the need for cleaning in the presence of a gas pressure drop of 0.02 MPa; to carry out the cleaning of the pipe and intertube space of the heat-exchange sections, the air-cooling apparatus of the gas is stopped, the gas is vented to the atmosphere. Disassemble the flange connections and heat exchange sections, which, after washing with steam from the steam generating unit and subsequent drying, are installed back into the gas air-cooling unit. Assemble in the reverse order.EFFECT: provision of complete cleaning of the pipe and intertube space of the heat exchange sections from mechanical impurities by using a dismountable structure.1 cl, 1 dwg
