摘要：

Porous cellulose and polyvinyl alcohol membranes were tested for dehydration of oil-water emulsion by pervaporation at different temperatures. Membranes having pore sizes that correspond to those of ultrafiltration membranes removed water effectively from oil-water emulsions. The permeation rate decreased with an increase in the oil content in the emulsion, probably due to a gradual change in the emulsion structure from the w/o/w (water-oil-water) to the o/w/o (oil-water-oil) type. The permeation rate increased with an increase in the operating temperature without a significant change in the oil separation. © 1991.
