“…The increasing trend with the RH indicates that the solution-diffusion mechanism has a small contribution toward CO 2 transport through the membrane. Similar trends were observed by other workers which indicated that faster rate of diffusion was due to the formation of HCO3 -through this water-swollen FSC membrane, which eventually exhibits high CO 2 permeance and consequently high selectivity [2,66,70]. Some of the water in the flue gas stream will inevitably permeate with the CO 2 in these facilitated transport membranes.…”

CO 2 emission from anthropogenic sources has raised global environmental concerns, and efficient reduction of these greenhouse gas emissions by capturing CO 2 is recognized world-wide as very important along with the implementation of new green energy technology. Membrane technology is considered to be one of the efficient techniques to be used for CO 2 capture. Among different types of membranes, mixed matrix membranes and facilitated transport membranes have gained much interest in recent years due to documented high CO 2 permeance through these membranes, especially when the gas is humid as is the case for flue gas from combustion. In the current review, a comprehensive discussion is focused on the development of hybrid membranes involving the selection of the fixed site carrier (FSC) membranes and the interaction of nanosilica-particles in a polymer membrane for efficient CO 2 capture. Other facilitated transport membranes and mixed matrix membranes are also briefly discussed.

“…Active transport materials demonstrate significantly higher selectivity, e. g. 160 for samples prepared as membranes for pilot scale experiments [17,18]. Unfortunately these membranes still have relatively thick separation layers and thus low permeance of about 1 m 3 (STP)/(m 2 h bar).…”

Abstract:Blend materials of Pebax ® 1657 and low molecular weight poly(ethylene glycol)s were studied for their stability at temperature up to 90°C. It was found that a threshold of molecular weight exists at which leaching out of the low molecular weight compound from the polymer matrix becomes minimal. Poly(ethylene glycol) with methyl end groups having a molecular weight of 500 g/mol provides a blend material with a CO 2 permeability coefficient higher than in case of Polyactive™. PEBAX ® /DM500 blend can be a cheaper alternative to tailor made Polyactive™ in large scale production of thin film composite membrane.

“…Based on this process, the membrane has a support coated and cross linked polyvinilamine, which serves as a fixed carrier of CO 2 and a "catalyst" (in the form of 3  with combination of moisture), helps quickly remove and transport CO 2 through the membrane lumen. It is reported through the improvement of this process, CO 2 /N 2 selectivity has approached 174 and 200 by the same research group [40,41].…”

CO 2 capture from post combustion does not need significant alteration of the current power generation facilities and is therefore of more interests to the research and industrial circles. Polymeric membrane separations, which are based mainly on physical phenomena, are easy for operation and to scale up. The details and future research trends are covered in this most updated review, which serve as an excellent technique reference for the research circle and technology evaluation for the related industrial circle.
