Effects of shape, porosity, and operating parameters on carbon dioxide recovery in polytetrafluoroethylene membranes
TL;DR: The recovery of carbon dioxide using an absorbent composed of 2-amino-2-methyl-l-propanol (AMP)+monoethanolamine (MEA)+piperazine (PZ) in polytetrafluoroethylene (PTFE) membrane contactors was investigated and an asymmetric membrane had a better CO(2) recovery than that of symmetric membrane.
