GAS FROM THE GAS PURIFICATION DEVICES PRODUCTION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC F17D1/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas production industry, in particular, to the gas cleaning units operation, and can be used in the gas production from purification devices, for example, of compressor stations. Gas from the gas purification device producing method is that the gas from the gas purification device is supplied into the gas distribution station pipeline, at that, the gas purification device is first switched off by closing the valves on both its sides, connecting the gas generation device from the gas purification devices, comprising the housing with inlet and outlet branch pipes, which is connected to the gas purification device outlet by the inlet branch pipe, and the outlet branch pipe is communicated with the environment, at that, at least one first and second shut-off valves are in series arranged in the housing, between which at least one outlet branch pipe is arranged, connected to shut-off valve by the pipeline, which is connected to the gas distribution station pipeline, opening the first shut-off valve and connected to the gas distribution station pipeline shut-off valve, closing the gas distribution station pipeline valve and, with the closed second shut-off valve, performing the gas generation from the purification device to the gas distribution station pipeline until creating the gas pressure of 0.7 MPa in the purification device, then closing the connected to the gas distribution station pipeline shut-off valve, opening the second shut-off valve and performing the gas production from the purification device until the atmospheric pressure creation therein.

EFFECT: enabling reduction in the discharged into the atmospheric air purified gas flow rate, increase in the gas production safety, preventing condensate and contaminants from entering the gas distribution station pipeline.
