A new membrane is combined with a novel process design to reduce energy costs in a CO2 recovery system developed by Membrane Technology and Research Inc. (MTR, Menlo Park, Calif.; www.mtrinc.com). The two-step system uses a membrane made of a hydrophilic rubbery polymer, formed into spiral-wound modules. The membrane is 10 times more permeable to CO2 than conventional membranes used for CO2, says...
