Patent ES-350354-A1 (ES)
Title: Cryogenic recovery vaporizer
IPC: F02C6/18
Filed: 1968-02-10
Abstract: The invention relates to a method of vaporizing liquefied natural gas by utilizing the hot exhaust gases of a gas turbine engine, the engine being utilized to generate power. In Fig. 1 a gas turbine engine 10 drives an electric generator 11 and the exhaust gases from the engine discharge through a heat exchanger 12 wherein liquefied natural gas at temperature of -258 F. supplied through line 14 is vaporized and discharges at a temerature of 60 F. to a point of use. The inlet air to the engine is at a temperature of 80 F. and the turbine exhaust gas is at 925 F. In Fig. 2 the inlet air to the gas turbine engine is cooled to 40 F. by passing through a pre-cooler 15 through which vaporized natural gas at 18 F. discharged from the vaporizer 12 is passed. Cooling of the intake air results in increased power from the gas turbine engine and so from the generator 11. In Fig. 3 the ambient air flowing through the pre-cooler 15a is cooled by passing liquefied natural gas at -258 F. direct from the storage container therethrough. The temperature of the inlet air is reduced to 0 F. and that of the liquefied natural gas is increased to -168 F. The liquefied gas is then passed through the vaporizer 12 where it is heated by turbine exhaust gases, the natural gas being thereby vaporized and discharging to a point of use at a temperature of 60 F. This additional cooling of the inlet air further increases the power of the gas turbine engine.
