Establishing the suitability of symmetric ultrathin wall polydimethylsiloxane hollow-fibre membrane contactors for enhanced CO 2 separation during biogas upgrading
Abstract(#br)A hollow fibre membrane contactor (HFMC) comprised of nonporous symmetric ultrathin wall polydimethylsiloxane (PDMS) fibres has been studied for biogas upgrading to establish if the ultrathin wall can enable low resistance to mass transfer coupled with enhanced selectivity for carbon dioxide (CO 2 ).
