Title (EN) HYDROCARBON GAS PROCESSING
(FR) TRAITEMENT DE GAZ D'HYDROCARBURE
Abstract:
(EN) A process and an apparatus are disclosed for a compact processing assembly to improve the recovery of C2 (or C3) and heavier hydrocarbon components from a hydrocarbon gas stream. The preferred method of separating a hydrocarbon gas stream generally includes producing at least a substantially condensed first stream and a cooled second stream, expanding both streams to lower pressure, and supplying the streams to a fractionation tower. In the process and apparatus disclosed, the tower overhead vapor is directed to an absorbing means and a heat and mass transfer means inside a processing assembly. A portion of the outlet vapor from the processing assembly is compressed to higher pressure, cooled and substantially condensed in a heat exchange means inside the processing assembly, then expanded to lower pressure and supplied to the heat and mass transfer means to provide cooling. Condensed liquid from the absorbing means is fed to the tower.
(FR) L'invention concerne un procédé et un appareil destinés à un ensemble compact de traitement pour améliorer la récupération de C2 (ou C3) et des composants hydrocarbures plus lourds d'un courant de gaz d'hydrocarbure. Le procédé préféré de séparation d'un courant de gaz d'hydrocarbure comprend généralement la production d'au moins un premier courant sensiblement condensé et d'un second courant refroidi, l'expansion des deux courants à une pression plus basse, et l'acheminement des courants dans une colonne de fractionnement. Dans le procédé et l'appareil décrits, la vapeur de tête de colonne est dirigée vers un moyen d'absorption et un moyen de transfert de chaleur et de masse à l'intérieur d'un ensemble de traitement. Une partie de la vapeur de sortie provenant de l'ensemble de traitement est comprimée à une pression plus élevée, refroidie et sensiblement condensée dans un moyen d'échange de chaleur à l'intérieur de l'ensemble de traitement, puis détendue jusqu'à une pression inférieure et acheminée au moyen de transfert de chaleur et de masse pour assurer un refroidissement. Le liquide condensé provenant du moyen d'absorption est introduit dans la colonne.
