Abstract

Membrane gas-solvent contactors are a viable approach for the absorption of carbon dioxide (CO2) into solvents, such as potassium glycinate, compared to traditional solvent absorption. The hollow fibre membrane design does have limitations, as the presence of the membrane adds extra resistance to mass transfer compared to traditional solvent absorption. To reduce the impact of this extra resistance it is necessary to increase mass transfer in the solvent and gas phase boundary layers. This investigation aimed to increase mass transfer in the gas phase boundary layer of a membrane contactor process by applying oscillating gas flow conditions. For an asymmetric polydimethylsiloxane membrane co..
