"Proof of concept: Integrated membrane distillation-forward osmosis app" by Lei Zheng, Kangkang Li et al.
Abstract This study investigated the removal of CO from flue gas by an integrated membrane distillation-forward osmosis (MD–FO) system. Monoethanolamine (MEA) and sodium glycinate solutions were loaded with CO from a mixture of CO and N (1:9 in volume ratio) to simulate synthetic flue gas. CO desorption from the amine solution was evaluated using MD at 80 °C. Interaction between amines and the membrane polymeric matrix could alter the membrane surface hydrophobicity; however, under all experimental conditions it was still sufficiently hydrophobic for MD operation. Amine loss during MD...
