METHOD OF SELECTING GAS OF STARTING, FUEL, PULSE AND FOR INTERNAL REQUIREMENTS FROM TECHNOLOGICAL COMMUNICATIONS OF COMPRESSOR SCHEMES OF COMPRESSOR STATION AS FUEL FOR DISARMING THE RELATED MACHINE TO REPAIR Russian patent published in 2018 - IPC F17D1/02 

FIELD: oil and gas industry.

SUBSTANCE: invention can be used for tapping of launching, fuel, impulse and for own needs from technological communications of compressor stations of the compressor station as a fuel at the output of an adjacent workshop for repair. The method includes stopping of working gas turbine units and closing the valves at the inlet/outlet of the compressor section (CS), opening the crane on the recirculation pipeline, transferring the gas extraction to the CS's own needs, opening the crane on the connecting pipeline between the fuel (launching) gas collectors and gas generation from the circuit CS. In addition, they provide a greater depth of gas evacuation from the disconnected communications of the compressor section by adjusting the standard isolation valves located at a distance less than 500 mm from the T-shaped connection of the section gas pipelines, by creating the ejection effect with partial closure of one of the cranes on the working gas pipeline of increased pressure and additional adjustment of the other on the ejected low pressure gas pipeline.

EFFECT: reduction of natural gas emissions from the compressor section communications to the atmosphere.
