Abstract:
In this research by using reverse osmosis process and a blend of membrane that are comprised of PDMS (poly dimethyl siloxane) and PEG (poly ethylene glycol)polymers, and also by means of Nano-composite TEOS (Tetraethyl orthosilicate) as crosslinking agent, total sulfur of finish diesel of Isfahan oil refinery decreased from 6380PPM (part per million) to around 1700 PPM. In the research,2 kinds of membrane including PDMS and blend of PDMS and PEG are used. The process variables in this research are pump pressure of membrane module, crosslinking agent consumption, crosslinking temperature, and crosslinking time. According to the research it is observed that by increasing pump pressure, crosslinking agent consumption and crosslinking temperature, the sulfur content of retentate stream decreases if other variables remain constant. However, the conditions are different for crosslinking time; when crosslinking time increases from 0.5 hour to 1 hour, sulfur content of retentate stream decreases but when the time increases to 1.5 hour and other variables remain constant, sulfur content increases.
