Abstract
Improving the energy efficiency of compressor stations is currently an urgent problem in the gas industry. Increasing the pressure of the transported gas by compression with the use of gas turbine units as a compressor drive is the most energy-intensive heat-and-power process. The article discusses modern methods of increasing the energy efficiency of compressor s tations with gas pumping units operating based on gas turbine plants by utilizing the heat of exhaust gases from gas turbine plants. A complex system is considered, which includes a gas pumping unit, a gas turbine unit, a waste heat boiler and an absorption refrigeration machine, which allows preheating the gas in front of the combustion chamber, cooling the air before compression and heating water for the compressor station’s own needs by utilizing the heat of flue gases after the waste heat boiler and utilizing low-potential heat of compressed gas air coolers.
