Abstract
Chemical absorption is the most common technology used in the Acid GasRemoval (AGR) systems for treating sour gases, but suffers from high regeneration energy and co-process produced water. Co-process produced water is often considered a waste by-product, but recently the industry is beginning to exploit it as a potential profit.
In this study, a novel integrated AGR and Forward Osmosis (FO) regeneration system is proposed to reduce the energy consumption in both systems, as well as treating the wastewater from the AGR units. This process utilizes ethanol as a draw solution (DS) along with n-pentane as a low boiling point agent for facilitating the separation of ethanol-water mixture at low temperature.N-pentane is the cross component between the AGR & FO units, through anew economizer coolant fluid replacing the circulated lean amine conventional cooling equipment “air cooler and trim cooler”.
