초록 ▼

A membrane separation process and system for removing a component from a fluid stream. An auxiliary membrane module or set of modules is installed across the second stage of a two-stage membrane separation system. The driving force for the auxiliary modules is provided by the pump or other driving unit for the first membrane stage. The auxiliary module or modules provides additional treatment of the residue stream from the second membrane stage, but are driven by the first stage driving unit. The invention is particularly useful in any membrane separation operation involving gas separation, vapor separation or pervaporation in which a two-stage system design is to be used, and where it is desirable to improve the efficiency of the two-stage system.

대표청구항 ▼

A method for increasing efficiency in a two-stage membrane separation system for removing a component from a fluid stream by gas separation, vapor separation or pervaporation, said system comprising: a first membrane unit; first driving means for said first membrane unit; and a second membrane unit connected to said first membrane unit and said first driving means such that a permeate stream from said first membrane unit becomes a feed stream for said second membrane unit; said method comprising: (a) connecting a permselective membrane to said system in such a way that a driving force for permeation of said permselective membrane is provided by said first driving means; (b) passing a residue stream from said second membrane unit across said permselective membrane, thereby producing a depleted stream depleted in said component compared with said residue stream and an enriched stream enriched in said component compared with said residue stream; (c) passing said enriched stream to an inlet side of said first driving means.
