FIELD: oil and gas industry.
SUBSTANCE: method consists in preliminary cleaning of gas supplied from the inlet header of main gas line, its compression in a process compressor of a gas transfer unit, cooling of transported gas, supply to the outlet header of the main gas line for further transportation. Cooling is performed additionally in a unit of recuperative heat exchangers. A compressor station includes an inlet header of the main gas line, a cleaning unit, a turbo-expander plant, inlet shutoff valves, a gas transfer unit with a process compressor and its drive, outlet shutoff valves, a gas cooler and a unit of recuperative heat exchangers connected in series or parallel, and an outlet header of the main gas line.
EFFECT: reduction of power costs for gas compression and improving the efficiency of gas transfer methods and compressor stations.
