CRYOGENIC PROCESS FOR THE RECOVERY OF NATURAL GAS LIQUIDS FROM LIQUID NATURAL GAS

摘要

A process for the recovery of natural gas liquids (NGL) (ethane, ethylene,propane, propylene and heavier hydrocarbons) from liquefied natural gas (LNG)is disclosed. The LNG feed stream (1) is split (22,23) with at least oneportion used as an external reflux (23), without prior treatment, to improvethe separation and recovery of the natural gas liquids (NGL).
