(EN) METHOD OF TREATING A HYDROCARBON STREAM COMPRISING METHANE, AND AN APPARATUS THEREFOR
(FR) PROCÉDÉ DE TRAITEMENT D'UN FLUX D'HYDROCARBURE CONTENANT DU MÉTHANE ET APPAREIL À CET EFFET
Abrégé
(EN)
In a method and apparatus for treating a hydrocarbon stream (110) comprising methane, at least a part (130) of the hydrocarbon stream (110) and a main refrigerant stream (310) are cooled by indirect heat exchanging against a pre-cooling refrigerant (230). The pre-cooled hydrocarbon stream (140) is passed to a first inlet (151) of an extraction column (125), and an effluent stream (160) is discharged from the extraction column (125). The effluent stream (160) and at least a part of the pre-cooled main refrigerant stream (320) are passed to a further heat exchanger (175), where they are both cooled thereby providing a cooled methane-enriched hydrocarbon stream (180) and at least one cooled main refrigerant stream (410,430). Said passing of the effluent stream (160) to the further heat exchanger (175) and said passing of the pre-cooled hydrocarbon stream (140) to the first inlet (151) of the extraction column (125) comprises indirectly heat exchanging the effluent stream (160) against the pre-cooled hydrocarbon stream (140).

Dans un procédé et un appareil de traitement d'un flux d'hydrocarbure (110) contenant du méthane, au moins une partie (130) du flux d'hydrocarbure (110) et un flux de réfrigérant principal (310) sont refroidis par échange indirect de chaleur avec un réfrigérant de pré-refroidissement (230). Le flux d'hydrocarbure pré-refroidi (140) est introduit dans une colonne d'extraction (125) à travers un premier orifice d'entrée (151) et un flux d'effluents (160) est évacué de la colonne d'extraction (125). Ledit flux d'effluents (160) et au moins une partie du flux de réfrigérant principal pré-refroidi (320) sont introduits dans un nouvel échangeur thermique (175), où ils sont refroidis, ce qui donne un flux d'hydrocarbure enrichi en méthane refroidi (180) et au moins un flux de réfrigérant principal refroidi (410, 430). Ladite introduction du flux d'effluents (160) dans ledit nouvel échangeur thermique (175) et ladite introduction du flux d'hydrocarbure pré-refroidi (140) dans ladite colonne d'extraction (125) à travers ledit premier orifice d'entrée (151) implique un échange thermique indirect entre le flux d'effluents (160) et le flux d'hydrocarbure pré-refroidi (140).
