CFD Simulation of Hydrogen Separation in Pd Hollow Fiber Membrane

In this article, hydrogen adsorption from gas mixture involve nitrogen and hydrogen by palladium hollow fiber membrane investigated and two dimensional model proposed for hydrogen adsorption in this model. This model has been evaluated based on equations (momentum and mass transfer) in all three parts (shell, membrane and tube) for existing gaseous compounds with using finite element method. The results of simulation validated by experimental data of hydrogen adsorption by palladium hollow fiber membrane. Modeling predictions shows good agreement with experimental data at different operating conditions such as different gas flows, temperature, pressure and etc. the result of simulation shows hydrogen separation efficiency increases with increasing temperature and pressure and decreases with increasing inlet rate. Also with using this model better performance of hollow fiber membranes can be obtained. In fact, hollow fiber membrane can be designed at different conditions and for different rates that it can save cost of various tests.
