GAS DECOMPRESSION PLANT, GAS REDUCTION STATION WITH SUCH PLANT, AND GAS DECOMPRESSION METHOD Russian patent published in 2012 - IPC F17D1/05 

FIELD: machine building.

SUBSTANCE: gas decompression plant includes gas expanding device providing the possibility of expansion, and thus pressure reduction of gas, and gas temperature increasing device in the zone adjacent to the gas expanding device. Gas temperature increasing device includes internal combustion engine using diesel fuel or bio fuel. Gas reduction station includes gas decompression plant, heat source capable of generating excess heat relative to the amount required for gas heating in order to maintain the temperature of the gas leaving the gas expanding device at gas reduction station above the specified temperature, heat exchanger for heat supply to heat release point, to heat absorber or to heat accumulator, and controller. Controller monitors the gas temperature and controls the heat amount supplied with heat exchanger to heat collection place, to heat absorber or to heat accumulator so that gas temperature can be controlled.

EFFECT: increasing the efficiency and improving reliability of high-pressure gas from the well.
