FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to gas industry. In the proposed method, the remaining gas is recycled from the end part of the emptying section by performing a sequence of switching valve shutoff. Residual pressure in process string, after equalizing pressure at inlet of first or second stage of Cenomanian booster compressor station, is recycled to flare of the field.
EFFECT: use of the method makes it possible to recycle part of gas from process string without displacement of operating characteristics of supercharger of gas transfer units of Cenomanian booster compressor station to zone of unstable operation, and also reduce losses of natural gas.
