    摘要: Power is generated by vaporizating liquefied natural gas by at least partially liquefying a multicomponent mixt. with the gas, pumping to elevated pressure, and expanding to produce power. The mixt. is heated to give a two-phase mixt. and the vapor is expanded. The mixt. pref. comprises methane, ethylene, propane and nitrogen. The appts. may include a heat-exchanger for heating the vapor from the seporator before entering the first expander.
