Description
Summary:An experimental and theoretical analysis of the membrane distillation process is presented for aqueous solutions containing ethanol. Different operational conditions are investigated for the air gap membrane distillation case. A computer simulation of the process is presented and compared with the experimental results; the effects of the relevant process parameters on the separation factor are then analyzed. The relevant role of the temperature difference between the evaporation and the condensation surfaces is pointed out, and the unexpected changes in selectivity with the feed composition are discussed.
