A simple model for a water gas shift membrane reactor

摘要: A simplified process model was developed to simulate a catalytic membrane water gas shift (WGS) reactor. number of computer simulations were conducted determine the potential increased carbon monoxide (CO) conversion in WGS reaction due simultaneous separation product hydrogen (H2) from reactant mixture. Gas factors based on Knudsen diffusion used these assess feasibility inorganic and ceramic membranes high-temperature, high-pressure (HTHP) coal gasification environment. The indicated that although increase CO concentration single reactor stage significant, multistage system would be needed above 90%. As expected, increasing feed pressure permeate ratio found concentration. At low ratios, predicted much better performance with countercurrent flow scheme when compared concurrent scheme. performance, course, depends strongly factors. With lower than ideal (e.g. H2 CO2 factor 2 instead value 4.7), simulation smaller
