Abstract:
A process for conditioning the inlet air to a combustion gas turbine comprising the steps of:(a) compressing a refrigerant gas vapor in a compressor and passing the compressed gas vapor to a condenser; (b) circulating cooling water from an evaporative cooling water tower to a condenser to indirectly cool the compressed gas vapor and condense the refrigerant; (c) circulating chilled water through a combustion gas turbine inlet cooling coil and through an evaporator/chiller; (d) passing the condensed vapor to said evaporator/chiller where the condensed refrigerant is allowed to evaporate thereby indirectly chilling said chilled water; (e) passing the evaporated refrigerant back to step (a), (f) heating a thermal oil utilizing the heat in the exhaust gas of the combustion gas turbine; (g) heating an ethylene glycol stream by indirect heat exchange with the heated thermal oil; and (h) circulating said ethylene glycol through said inlet cooling coil thereby heating the combustion gas turbine inlet air.
