Abstract
Lager scale NaA/PAN composite membranes are prepared by scratching method. The separation performance of membrane is evaluated by pervaporation with DMF/H2O mixtures in this study. The influences of feed compositions, operation temperatures and feed flow on the pervaporation performance are investigated. The results show that the permeation flux increases with increasing the operation temperature. The permeation flux and separation factors of NaA/PAN membrane can reach 1.84 kg·m-2·h-1 and 11.54, respectively, under the following conditions: 20% mass fraction of DMF in feed, 24°C of operation temperature, 1.5 m3/h of feed flow and 500 Pa of downstream pressure.
