▎ 摘　　要

NOVELTY - A membrane distillation system comprises membrane module; and carbon nanotube and graphene oxide membrane that together define a nanocarbon immobilized membrane, which is associated with the membrane module. Nanocarbon immobilized membrane is sized to separate an organic solvent. USE - A membrane distillation system for separating a chemical constituent from water, preferably tetrahydrofuran (claimed). Can be used in alcohol concentration or recovery for use in paint or pharmaceutical industries, and in other applications including, but not limited to, solvent usage in paint, plastic, petroleum and/or pharmaceutical industries. ADVANTAGE - The membrane distillation (MD) system can enhance and/or maximize vapor flux, providing an enhanced solvent removal rate from the feed solution. Preferential sorption of the organic, specifically tetrahydrofuran (THF), on a hybrid reduced graphene oxide-carbon nanotube immobilized membrane contributes to enhanced solvent removal of the MD system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for separating a chemical constituent from water, which involves providing sweep gas membrane distillation module having a graphene oxide-carbon nanotube immobilized membrane; and passing a feed solution through the sweep gas membrane distillation module to separate the chemical constituent from the water.
