Synthesis of SAPO-34 membranes for separation of water/Acetic Acid mixture through vapor permeation test

摘要

Acetic acid is one of the most important intermediate in chemical industry. Dehydration of acetic acid requires large energy as the relative volatility of water to acetic acid is close to unity. Vapor permeation (VP) separation is a technology, where a membrane separation process uses vapor mixtures as feed. In this case, the driving force for transport through the membrane is the difference in the partial pressures between feed and permeation sides. In this study we have investigated the water/acetic acid mixture separation properties through SAPO-34 membrane synthesized on an alumina support.
