ABSTRACT:
The present invention is a filtering and chemical separation device that performs the operations of solvent extraction and pervaporation in a single piece of equipment, configured as a spiral-wound membrane module, and provides for the replenishment of the solvent in the supported liquid membrane while the module continues in operation. It provides a solution to the problem of separating miscible compounds efficiently and with low energy requirements.
