FIELD: energy saving and ecologically safe technologies of gas transportation pipe lines; mounting new and up-dating acting lines. SUBSTANCE: heat of flow of gas being transported is extracted by thermal pumps at compressor station inlets; this heat as well as heat of exhaust gases of gas-turbine plants is used for generating of additional output power of gas superchargers which is transformed into electric power used by gas-transfer units, this reducing consumption of primary energy resources for gas pipe line transport and ensuring efficient use of secondary energy resources of gas lines. EFFECT: enhanced efficiency. 1 dwg
