▎ 摘　　要

NOVELTY - Breaking of an azeotrope involves feeding a fluid mixture (A) through a membrane system comprising at least two graphene oxide-containing membranes. The fluid mixture (A) comprises a fluid component (F1) at a concentration (C1), and a fluid component (F2). The concentration (C1) is 0.1-10 mol% of the azeotropic concentration. The feeding of the fluid mixture (A) through the membrane system produces a fluid mixture (B) having a concentration (C2) of the fluid component (F1) greater than the azeotropic concentration. USE - Breaking of azeotrope for concentrating fluid components (claimed). ADVANTAGE - The method enables breaking of azeotropes, and suppresses the need for reducing pressure before communicating through the graphene oxide-containing membrane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for concentrating fluid component (F1) in fluid mixture (A). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating hybrid distillation and separation process.
