Title
(EN) HYDROCARBON GAS PROCESSING
(FR) TRAITEMENT D'HYDROCARBURES GAZEUX
Abstract
(EN) A process and an apparatus are disclosed for a compact processing assembly to recover C2 (or C3) components and heavier hydrocarbon components from a hydrocarbon gas stream. The gas stream is cooled and divided into first and second streams. The first stream is further cooled, expanded to lower pressure, and supplied as a feed between two absorbing means. The second stream is expanded to lower pressure and supplied as a bottom feed to the lower absorbing means. A distillation liquid stream from the bottom of the lower absorbing means is heated in a heat and mass transfer means to strip out its volatile components. A distillation vapor stream from the top of the heat and mass transfer means is cooled by a distillation vapor stream from the top of the upper absorbing means, thereby forming a condensed stream that is supplied as a top feed to the upper absorbing means.
(FR) L'invention concerne un procédé et un appareil pour une installation de traitement compacte afin de récupérer des composants en C2 (ou en C3) et des composants d'hydrocarbure plus lourds provenant d'un courant d'hydrocarbures gazeux. Le courant gazeux est refroidi et divisé en un premier et en un second courant. Le premier courant est davantage refroidi, subit une expansion à une pression inférieure, puis est amené comme alimentation entre deux moyens d'absorption. Le second courant subit une expansion à une pression inférieure, puis est amené comme alimentation par le bas au moyen inférieur d'absorption. Un courant de liquide de distillation provenant du bas du moyen inférieur d'absorption est chauffé dans un moyen de transfert de chaleur et de masse pour le débarrasser de ses composants volatiles. Un courant de vapeur de distillation provenant du haut du moyen de transfert de chaleur et de masse est refroidi par un courant de vapeur de distillation provenant du haut du moyen supérieur d'absorption, formant ainsi un courant condensé qui est amené comme alimentation par le haut au moyeu supérieur d'absorption.
