Abstract
A system for liquefying and subcooling natural gas wherein compression power is shifted off the closed cycle refrigerant by subcooling the liquid natural gas to a relatively warm exit temperature and subsequently reducing the pressure and flashing the liquefied natural gas to recover a gaseous phase natural gas in excess of plant fuel requirements, the excess being recompressed and recycled to the feed to the process.
