Abstract

The present work aims at developing a computational model for the prediction of oxygen separation through La2NiO4 disk shaped membranes. The influence of oxygen concentration on the permeation rate was studied experimentally. The model has been validated by comparing the numerical results with those of experiments. The optimal diameter of the inner tube for sweep gas and its distance (gap height) from the membrane surface for maximum oxygen permeation has been investigated. For the present geometry, the optimum gap height (P) is in the range of 0.85-1.25 mm and the optimum diameter (Di) is in the range of 1.5-2.5 mm. Finally it is concluded, as indicated by the numerical and experimental investigations, that with increase in the ratio of O2/N2 mixture on the feed side the oxygen permeation rate increases.
