Ba-SAPO-34 Zeolite Membrane for CO₂/N₂ Separation: Process Optimization

Abstract:

In the present research, Ba-SAPO-34 membrane was formed using microwave heating and ion-exchange process. The membrane was subjected to CO₂/N₂ separation process considering 3 independent process variables as temperature, pressure difference across the membrane and CO₂ % in the feed. Response surface methodology coupled with central composite design, available in Design Expert software was used to perform optimization for the 2 response CO₂ permeance and CO₂/N₂ separation selectivity as a function of the 3 independent process variables. The optimum CO₂ permeance and CO₂/N₂ separation selectivity was 17.54x10^-7 mol/m².s.Pa and 58.82 respectively at 30 ^oC, 145.10 kPa pressure difference and 5 % CO₂ in the feed.
