In order to increase the permeation trough the membrane a sweep gas (e.g., N2 or steam) is employed. However, separation will be required downstream. As a consequence, the sweep gas remotion accompanied by a pressure increment allows high permeation and no H2 purification. The aim of the present work is to simulate a multitubular membrane reactor for the WGS reaction, without sweep gas, under two flow configurations: co- and countercurrent. The effect of the flow schemes on the reaction ignition, temperature axial profiles and CO conversion is analyzed.
