STUDY ON THE EFFECT OF WATER VAPOR ON O_2 AND C_2H_2 PERMEATING THROUGH POLYSULFONE HOLLOW FIBER MEMBRANES

摘要

Recently, Polysulfone hollow fiber membranes were widely applied in dehydration process, Such as in air and nature gas dehydration. Special permeation behaviors of water vapor through symmetrical membrane were studied popularly. However, the report on permeation behavior through hollow fiber membranes is still seldom. Moreover, the result are various with different mean and different aim of experiment. In our study, dry O_2 and dry C_2H_2 permeation flow rate through dry-treated polysulfone hollow fiber membranes, and the effect of water vapor on O_2 and C_2H_2 permeation flux through polysulfone hollow fiber membranes were investigated.
