Enhancement of hydrocarbon permeation by polar additives in liquid emulsion membranes
Journal of Chemical Engineering of Japan
This paper describes the enhancement of hydrocarbon (HC) permeation through liquid emulsion membranes consisting of water, an emulsifying agent and a polar additive such as sulfolane or triethylene glycol (TEG). The addition of sulfolane caused both an increase in membrane breakup and a decrease in mechanical entrainment. Moreover, sulfolane considerably enhanced the permeation of HCs, although selectivity decreased with increasing sulfolane concentration. Whenthe volumefraction of sulfolane indoi:10.1252/jcej.20.585 fatcat:7su6e6m7n5bfzbpwliadcs6bly
