ABSTRACT:
A process for separating a first component of a process stream from a second component of a process stream in a single vessel has been developed. The separation process uses an apparatus having a distillation zone to separate a first component from a second component of a process stream, thereby producing a distillation zone overhead stream enriched in the first component, and a membrane separation zone containing a membrane capable of selectively removing additional amounts of the second component from the distillation overhead stream. The benefit is the production of a high purity process at lower capital equipment costs.
