Abstract
Liquified petroleum gas or natural gas liquids may be recovered from liquified natural gas by receiving an input stream comprising substantially rich liquified natural gas, splitting the input stream into a direct stream and a bypass stream, heating the direct stream in a cross-exchanger to produce a stream of heat rich liquified natural gas, splitting the heated rich liquified natural gas into a primary column feed, an optional bypass stream and a secondary column feed.
