METHOD AND DEVICE FOR PRODUCING ALKENE DERIVATIVES

摘要

The invention relates to a method for producing a flow containing at least one alkene derivative, including the following steps: a step a) of reacting a flow containing one or more alkenes and one or more alkanes—the ratio of said alkanes to said alkenes being at least 1 by volume—with a flow containing mainly oxygen, in order to obtain at least one converted flow containing at least said alkene derivative; a step b) of separating the converted flow produced in step a) into at least said flow containing at least said alkene derivative and a residual flow containing mainly one or more hydrocarbons and one or more inert compounds; and a step c) of separating all or a portion of said residual flow by means of permeation into at least one first flow containing mainly one or more inert compounds and a second flow containing mainly one or more hydrocarbons.
