Abstract : A novel integration between Acid Gas Removal (AGR) and Forward Osmosis (FO) regeneration system is
proposed to reduce the energy consumption in both systems: in the AGR and FO regeneration unit. This process utilizes
Ethanol (EtOH) as a draw solution coupled with n-pentane as a low boiling point agent. A low boiling point light
hydrocarbon immiscible in water is used to facilitate the separation of ethanol-water mixture at low operating temperature.
The light hydrocarbon is used as a cross component between AGR & FO units; it is used to reduce AGR energy
consumption and ensuring smooth operation by replacing the circulated lean amine conventional cooling equipment “air
cooler and trim cooler” with a new economizer, where the light hydrocarbon (n-pentane) is used as the economizer coolant
fluid. This work has been developed using Aspen HYSYS V8.8. The results show that the novel integration between AGRFO
process could save 17 to 20 % of new AGR plants capital cost (Capex) due to eliminating some cooling equipments in
AGR system.
