LIQUID NATURAL GAS PROCESSING

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 (201) is split (202, 203) with at least one portion used as an external reflux (203, 210, 211), without prior tre...

Zusammenfassung:	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 (201) is split (202, 203) with at least one portion used as an external reflux (203, 210, 211), without prior treatment, to improve the separation and recovery of the natural gas liquids (NGL) (214). Procédé d'extraction de liquides du gaz naturel (éthane, éthylène, propane, propylène et hydrocarbures plus lourds) à partir de gaz naturel liquéfié. Le flux de charge de gaz naturel liquéfié est divisé, au moins une partie de celui-ci servant de reflux externe, sans traitement préalable, pour améliorer la séparation et l'extraction de liquides du gaz naturel.
