Membrane separation of water from aqueous mixtures

摘要: Water is separated from aqueous mixtures of organic and inorganic compounds by contacting the mixture against a first surface polymeric membrane selectively permeable to water, second with sweep liquid having thermally dependent water miscibility, withdrawing enriched miscible surface, forming rich phase through thermal adjustment withdrawn water-enriched liquid. The selected those liquids normal or inverted miscibility for which allow separation water-rich phase.
