Removal of Sulfur from MTBE by Pervaporation Process

Abstract:

With fog and haze increasingly severe pollution and tighter environmental legislation in China. It is urgent for refinery to reduce sulfur content in MTBE and produce cleaner fuels by deep desulfurization technology. The feasibility of pervaporation (PV) process for removal of sulfur from MTBE was investigated in this study. Adsorption capacities of three different membrane materials such as PDMS, naffion membrane with H and Na forms were compared by immersion tests. PDMS membrane showed better adsorption abilities for MTBE and disulfide. In addition, the adsorption of PDMS membrane in pure MTBE and dimethyldisulfide solution were investigated at 308.15K and 313.15K. It was indicated that increasing operation temperature facilitated to increase the adsorption amount and decrease the time for reaching adsorption equilibration. This research has guiding significance for removal of sulfur from MTBE by PV process.
