- •
Pressure swing membrane absorption (PSMAB) separates CO2–He (H2 surrogate) mixture.
- •
Separation of 40% CO2 in He (shifted syngas) was studied at 50–100 °C, 689–1724 kPag.
- •
Two absorbents, PEG 400 and ionic liquid (IL), were used with/without a dendrimer amine.
- •
Despite higher CO2/He selectivity, PEG 400 performs poorly due to higher viscosity.
- •
PSMAB with IL and dendrimer amine yields 95.5% CO2 from a 100 °C–1724 kPag feed gas.
