Abstract

La présente invention se rapporte à un procédé d'isomérisation de butane normal, qui consiste : à fractionner l'effluent d'isomérisation (108, 114) dans un déisobutaniseur (116), afin d'obtenir une fraction d'ébullition inférieure (118) contenant au moins 80 % poids d'isobutane, et une fraction d'ébullition supérieure (122) contenant du butane normal et au moins 10 % poids d'isobutane ; à mettre la fraction d'ébullition supérieure (122) en contact avec une membrane sélectivement perméable (124), afin de former un perméat (126) contenant du butane normal et un rétentat (128) contenant au moins 80 % poids d'isobutane. Les membranes préférées sont des membranes de criblage présentant un indice de flux de perméat C4 d'au moins 0,01, et un rapport de flux de perméat C4 d'au moins 1,25:1.
