Abstract
Apparatus is disclosed for economical separation of fluid mixtures. Broadly, apparatus of the invention comprises modules using solid perm-selective membranes. More particularly, the invention relates to a plurality of membrane modules disposed in a first product group, a second product group, and optionally one or more intermediate group. Apparatus of the invention with the membrane modules in multiple groups is beneficially useful for simultaneous recovery of a very pure permeate product and a desired non-permeate product from a mixture containing organic compounds.

Apparatus using perm-selective membranes in multiple groups for simultaneous recovery of a very pure permeate product and a desired non-permeate product from a fluid mixture of compounds, which apparatus comprises
- (1-A) a plurality of membrane modules disposed in a first product group, one or more intermediate group, and a second product group, each module comprising a solid perm-selective membrane which under a suitable differential of a driving force exhibits a permeability of at least 0.1 Barrer, a channel having at least one inlet and one outlet for flow of fluid in contact with one side of a membrane, and contiguous with the opposite side thereof a permeate chamber having at least one outlet for flow of permeate,
- (1-B) means for distribution of a fluid feedstock into the channel inlets of at least a portion of the intermediate group of modules,
- (1-C) means for collection of permeate effluent from the chamber outlets of at least a portion of the intermediate group of modules and distribution of this intermediate permeate into the channel inlets of the first product group modules,
- (1-D) means for collection of a permeate product effluent from the chamber outlets of the first product group of modules,
- (1-E) means for collection of non-permeate effluent from the channel outlets of the first product modules and distribution thereof into the channel inlets of at least a portion of the intermediate group of modules,
- (1-F) means for collection of non-permeate from the channel outlets of the intermediate group of modules and distribution of this intermediate non-permeate into the channel inlets of the second product group modules, and
- (1-G) means for collection of a non-permeate product effluent from the channel outlets of the second product group of modules.
