Abstract:
In this study, hydrogen separation process from a gas mixture using industrial polyimide hollow-fiber membrane module was simulated using CFD. Polymeric hollow-fiber membranes are using now in industrial plants for H2 recovery because of their good factors such as high ratio of surface area to volume, enough H2 permeability as well as the ability to withstand high feed gas pressure. In order to simulate the momentum transfer in the shell side of membrane module, k-ω and k-ε turbulent models were used. The model equations related to retentate side, membrane and permeate side with the appropriate boundary conditions, were solved using COMSOL Multiphysics software version 5.2a. In order to ensure the accuracy of the modeling results, the results of the k-ω and k-ε models were compared with industrial result. According to the modeling results, the result of the k-ω model was more accurate than k-ε model
