METHOD OF GAS PUMPING OUT FROM GAS MAIN SHUT-OFF SECTION AND MOBILE COMPRESSOR PLANT TO THIS EFFECT Russian patent published in 2008 - IPC F04B41/00 F17D1/02

Abstract RU 2330182 C1

FIELD: engines and pumps.

SUBSTANCE: in compliance with the proposed method, gas pressure in the compressor is increased to the level exceeding that in the operated gas main section, then the compressed gas pressure is reduced to that in the said operated gas main section. The compressor plant to pump out gas from the shut-off section into the operated gas main section incorporates the compressor with its inlet connected to the shut-off section outlet and a gas pressure reducing device with its inlet connected to the compressor outlet and its outlet connected to the operated gas main section outlet.

EFFECT: pumping out natural gas from the shut-off section into the operated gas main section without thermal destruction of the gas main antirust coating.
