Abstract :
Separation performance of Faujasite NaX zeolite membrane was studied for water-unsymmetrical dimethylhydrazine (UDMH) mixture using pervaporation (PV). A comprehensive transient model was developed using COMSOL Multiphysics software version 5.2. The developed unsteady state 2D model was capable of predicting concentration distribution in both membrane and feed phases. The membranes showed good selectivity towards water in the water-UDMH mixtures. Water permeates faster because of its preferential adsorption into the Nano-pores of the hydrophilic zeolite membrane. In PV of water-UDMH mixtures, the membrane exhibits a hydrophilic behavior, with a high selectivity towards water and a good flux. The best NaX membrane had a water flux of 2.67 kg/m2.h at 27oC. The best PV selectivity was obtained to be 40.
