A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is divided into first (35) and second (32) streams, and the second stream (32) is expanded to the fractionation tower pressure and supplied to the column (18) at a mid-column feed position (33a, 34a). A recycle stream (39) is withdrawn from the tower overhead after it has been warmed and compressed, and is combined with the first stream (35). The combined stream (38) is cooled to condense substantially all of it, and is thereafter expanded to the fractionation tower (18) pressure and supplied to the fractionation tower at a top column feed position (38c). The pressure of the compressed recycle stream and the quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered.
La présente invention se rapporte à un procédé permettant de récupérer l'éthane, l'éthylène, le propane, le propylène et des composants d'hydrocarbures plus lourds, à partir d'un courant de gaz d'hydrocarbures. Le courant est fractionné en premier (35) et en second (32)courants, le second courant (32) étant d'abord dilaté jusqu'au niveau de pression de la tour de fractionnement avant d'être amené jusqu'à mi-colonne (33a, 34a). Un courant de recyclage (39) est chauffé, comprimé puis retiré de la tête de la colonne (18) avant d'être combiné au premier courant. Le courant combiné (38) est refroidi jusqu'à quasi-condensation, puis il est dilaté jusqu'au niveau de pression de la tour de fractionnement. Le courant est ensuite amené à la tête (38c) de la tour de fractionnement (18). La pression du courant de recyclage dilaté, ainsi que la quantité et la température de l'alimentation de la colonne sont effectifs de façon à maintenir le distillat de tête à une température à laquelle la partie principale des composants désirés est récupérée.
