A process for the recovery of ethane, ethylene, propane, propylene, and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled and divided into first and second streams. The first stream is further cooled to condense substantially all of it and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a first mid-column feed position. The second stream is expanded to the tower pressure and is then supplied to the column at a second mid- column feed position. A vapor distillation stream is withdrawn from the column above the feed point of the second stream and is then directed into heat exchange relation with the tower overhead vapor stream to cool the vapor distillation stream and condense at least a part of it, forming a condensed stream.

L'invention concerne un procédé permettant l'extraction d'éthane, d'éthylène, de propane, de propylène et de constituants hydrocarbures plus lourds à partir d'un flux de gaz d'hydrocarbures. Le flux est refroidi et divisé en un premier et un second flux. Le premier flux est encore refroidi pour condenser presque en totalité et il est ensuite détendu jusqu'à atteindre la pression de la tour de fractionnement vers laquelle il est acheminé au niveau d'une première position d'alimentation à mi-colonne. Le second flux est détendu jusqu'à atteindre la pression de la tour et il est ensuite acheminé vers la colonne au niveau d'une seconde position d'alimentation à mi-colonne. Un flux de distillation de vapeurs est extrait de la colonne au-dessus du point d'alimentation du second flux, puis dirigé dans un échange de chaleur avec le flux de vapeurs de tête de la tour pour refroidir le flux de distillation de vapeurs et en condenser au moins une partie pour former un flux condensé.
