초록 ▼

The present invention provides counter flow cascade separation systems useful to separate solute/solute pairs present in a solvent. The separation systems include a series of interconnected stages with each stage comprising a combination of a diafilter preferentially permeable for one solute and an ultrafilter that accepts a permeate flow from the diafilter. The ultrafilter is permeable to solvent. Solute/solute pairs are preferentially separated by the diafilter into permeate and retentate flows and excess solvent is removed from the permeate flow by the ultrafilter and recycled back into the system. Stages are combined to form a counter flow cascade separation system capable of operation approaching an ideal counter flow cascade.

대표청구항 ▼

What is claimed is: 1. A counter flow cascade separation system for separating a solute/solute pair in a solvent, comprising a series of interconnected stages in which each stage comprises: a feed for accepting a flow stream containing a solute/solute pair in a solvent; a diafilter in communication with the feed wherein said diafilter has a diafilter membrane preferentially permeable for a first solute of the solute/solute pair in the solvent and less permeable to the second solute wherein said first solute is preferentially conveyed to a diafilter permeate flow and the remaining second solute is preferentially retained in a diafilter retentate flow; and an ultrafilter positioned to accept said diafilter permeate flow wherein said ultrafilter has an ultrafilter membrane exclusively permeable to the solvent contained in the diafilter permeate flow wherein solvent in the diafilter permeate flow passes through said ultrafilter membrane to a solvent flow; wherein said series of interconnected stages includes a first feed stage receiving said flow stream from a source outside the system, the stream retained by the diafilter of the feed stage is directed to a second stage and the stream retained by the ultrafiltration membrane in the feed stage is directed to a third stage, wherein the stages are interconnected so that each stage beyond a first stage accepts an intermixed flow stream formed by combining retentate flow and permeate flow from different subsequent stages, wherein the intermixed retentate and permeate flow each has the solute/solute pair present in substantially the same molar ratio; the first solute and second solute exiting said system at different terminal stages. 2. The counter flow cascade separation system according to claim 1 comprising three stages. 3. The counter flow cascade separation system according to claim 1 wherein said solvent flow from at least one of said stages is recycled within the system. 4. The counter flow cascade separation system according to claim 1 wherein at least one stage further comprises a macroporous membrane positioned to accept the solvent flow and spatially distribute said solvent over the diafilter membrane. 5. The counter flow cascade separation system according to claim 1 wherein at least one stage includes said diafilter and ultrafilter within a single housing. 6. A method for separating a solute/solute pair in a solvent using a counter flow cascade separation system, said method comprising steps of: routing a flow stream containing a solute/solute pair in a solvent to a feed; routing said flow stream to a diafilter in communication with the feed wherein said diafilter has a diafilter membrane preferentially permeable for a first solute of the solute/solute pair in the solvent and less permeable to the second solute wherein said first solute is preferentially conveyed to a diafilter permeate flow and the remaining second solute is preferentially retained in a diafilter retentate flow; and routing said diafilter permeate flow to an ultrafilter positioned to accept said diafilter permeate flow wherein said ultrafilter has an ultrafilter membrane exclusively permeable to the solvent contained in the diafilter permeate flow wherein solvent in the diafilter permeate flow passes through said ultrafilter membrane to a solvent flow; wherein said series of interconnected stages includes a first feed stage receiving said flow stream from a source outside the system, the stream retained by the diafilter of the feed stage is directed to a second stage and the stream retained by the ultrafiltration membrane in the feed stage is directed to a third stage, wherein the stages are interconnected so that each stage beyond a first stage accepts an intermixed flow stream formed by combining retentate flow and permeate flow from different subsequent stages, wherein the intermixed retentate and permeate flow each has the solute/solute pair present in substantially the same molar ratio; the first solute and second solute exiting said system at different terminal stages.
