Ba-SAPO-34 Zeolite Membrane for CO<sub>2</sub>/N<sub>2</sub> Separation: Process Optimization Academic Article uri icon

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.
