Patent number: 4532347Abstract: The instant invention relates to a membrane solvent extraction and reaction system. More particularly it pertains to an improvement in the membrane solvent extraction system wherein a solute is extracted through a polymeric membrane from one solvent liquid phase to an extracting solvent liquid without direct contact between the liquid phases which are separated by the membrane and in which the extracting solvent has no greater solubility and usually substantially less solubility for the solute than the feed solvent. The impovement comprises converting the solute permeating across the membrane to a different chemical compound, whereby a high concentration gradient for the solute across the membrane is maintained to improve the separation of the solute from the feed solvent liquid phase.Type: GrantFiled: January 21, 1980Date of Patent: July 30, 1985Assignee: Varen TechnologyInventor: Ronald J. Vaughan
