RECOVERY OF POWER FROM VAPORIZATION OF LIQUEFIED NATURAL GAS

摘要

Power is recovered from the vaporization of natural gas by warming the natural gas against a multicomponent stream which is cooled and liquefied. The liquefied multicomponent stream is pumped to an elevated pressure and is warmed against one or more streams of propane which are cooled and liquefied. The warmed multicomponent stream is heated, expanded through a generator loaded expander and recycled. The liquefied propane is pumped to an elevated pressure in single or multi-staged streams, vaporized, expanded through a second generator loaded expander and recycled.
