  • Olefins-paraffins separation process by membrane
    Patent number: 12186707
    Abstract: The present invention relates to an olefins-paraffins separation process in feed stream containing hydrocarbons with 2 to 4 carbon atoms by facilitated transport membrane specific to olefins, comprising a step (a) of feeding the feed stream containing hydrocarbons with 2 to 4 carbon atoms into distillation column and at least 1 stage of membrane unit connected to distillation column at the feed of distillation column and at least 1 stage of membrane unit connected to the side draw of distillation column and a step (b) of separating a portion of feed stream that is passed from the membrane unit, at least 1 stream is the product stream that mostly comprising olefins and at least 1 stream that mostly comprising paraffins.
