Efficiency Improvement through Process Integration of Chemical Looping Combustion and Membrane Assisted Chemical Looping Mohammed N. Khan, Schalk Cloete, Shahriar Amini


Chemical looping combustion and reforming are promising technologies for converting fossil fuel into power and hydrogen (H2). However, the temperature limitations in the reactor reduce their attractiveness. In the current study, an additional combustor is added to increase the turbine inlet temperature. Furthermore, three different process integration between CLC plant and membrane-assisted CLR plant are evaluated. Direct integration results in an efficiency of 53.08%. With further process integration, the plant can produce both power and H2 with efficiencies 54.46% and 68.09%, respectively. The results show significant improvement in efficiency when compared to natural gas combined cycle and steam-methane reforming technologies.
