Title (EN) LIQUID NATURAL GAS PROCESSING
(FR) TRAITEMENT DE GAZ NATUREL LIQUIDE
Abstract:
(EN) A process for the recovery of LPG from liquefied natural gas (LNG) is disclosed. The LNG feed stream is subjected to a two stage separation process where the bottoms from the first stage separation containing C2+ hydrocarbons is split into three portions, one portion is fed directly to the top of the second separation stage as a reflux stream, a second portion is warmed and partially vaporized by cross heat exchange with overhead vapors from the second separation stage before being fed to the middle of this second separation stage, and the third portion is heated and vaporized by cross heat exchange with bottom liquids from the second separation stage prior to being fed into the bottom of this same separation stage.
(FR) L'invention porte sur un procédé pour la récupération de GPL à partir de gaz naturel liquéfié (GNL). Le courant de charge de GNL est soumis à un procédé de séparation à deux étages dans lequel le produit de fond provenant de la séparation du premier étage contenant des hydrocarbures en C2+ est divisé en trois parties, une partie est introduite directement en haut du second étage de séparation comme courant de reflux, une deuxième partie est réchauffée et partiellement vaporisée par échange de chaleur croisée avec des vapeurs de tête provenant du second étage de séparation avant d'être introduite dans le milieu de ce second étage de séparation, et la troisième partie est chauffée et vaporisée par échange de chaleur croisée avec les liquides de fond provenant du second étage de séparation, avant d'être introduite dans le fond de ce même étage de séparation.
