Abstract

An expanded (102) and cooled (106) crude LNG stream (108) is separated in a nitrogen rejection column (150) into a nitrogen-enriched overhead vapor stream (130) and a nitrogen-diminished bottoms liquid stream (110). The bottoms stream (110) is pumped (112) to higher pressure, divided into first and second streams (114 & 116) and then the second stream is reduced in pressure and at least partially vaporized (118) by heat exchange (106) against the crude LNG feed stream (104) to cool said feed stream and provide (120) boilup to the nitrogen rejection column (150).
