GAS-TURBINE EXPANSION MACHINE OPERATION PROCESS Russian patent published in 1997 - IPC

Abstract RU 2096640 C1

FIELD: gas-dispensing and gas-control stations. SUBSTANCE: natural gas is passed at high pressure through heat exchangers 2-3 from line 1 to turbo-expander 4 wherein its pressure is reduced to level desired for user. Turbo-expander power added to power of gas-turbine engine 6 is applied to electric generator 20. Natural gas is heated by exhaust gases of engine 6 prior to arriving at turbo-expander 4. Temperature of natural gas supplied to user is controlled by controlling flows with aid of elements 17 and 22. EFFECT: improved heat recovery and use of natural gas gage pressure. 1 dwg
