Abstract:

In this paper, a novel gasification-based system integrated with two chemical looping processes, namely, one designed for H2 production using a three-reactor chemical looping hydrogen generation (CLHG) process and other one for O2 production using a two-reactor chemical looping air separation (CLAS) process was modeled and its performance estimated. In addition, the system integrated a hot gas cleaning unit for the removal of syngas contaminants at high temperature. Aspen Plus process simulation software was employed in the study to design and develop a detailed process model. The results show that the proposed system configuration can achieve better performances than conventional plants, capture almost all of the feedstock carbon, and generate low CO2 emissions. Moreover, the system becomes carbon negative when considering the carbon neutrality of the biomass fuel.
