Abstract:
During membrane operations, the composition of each flow (permeate and retentate) can vary depending on both the operational conditions and on feed composition. This study focuses on the dependency of permeate flow composition and recoveries of main components on feed syngas composition and pressures in permeate and retentate flows. Using a polyimide hollow fiber module and a laboratory membrane unit, several process characteristics were studied. A dependency between component permeability and the effect of pressure conditions on the process was observed – for higher permeability components, the concentration in the permeate decreases with increasing pressure difference and for lower permeability components, the concentration increases with increasing pressure drop. Also, a dependency between composition of the feed gas and components recoveries was shown indicating that in mixtures with higher content of more permeable components, the recoveries are higher. The differences in recoveries also vary with increasing pressure difference.
