The mass transfer of hydrogen in the simplified Johnson Matthey membranemodule is modelled in order to increase the understanding of the mass transfer characteristics of the module. The computational fluid dynamical software package CFDS-FLOW3D is used for this purpose. The Johnson Matthey module is simplified in the model as two coaxial cylinders representing the annular flow of feed gas and the pipe flow of sweep gas. Both flows are countercurrent and are separated by the membrane. Atmospheric temperature and pressure, and binary gas mixtures are assumed in the simplified membrane module. The modelling results demonstrate the strong coupling between hydrodynamics and the hydrogen separation performance of the module. 6 refs.
