Separation performance of PVAm composite membrane for CO2 capture at various pH levels

Role of Facilitated Transport Membranes and Composite Membranes for Efficient CO2 Capture – A Review

“…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.…”

“…PSf is considered to be one of the good support materials due to properties in terms of good thermal and mechanical stability, ease of manufacturing, reproducible properties and good gas transport properties. PSf has been successfully used in several studies for CO 2 capture in FSC membranes [2,63,67,68]. [65] a) b) Figure 3.…”

“…She has around 80 peer reviewed membrane articles in international highly recognized journals. Her group is currently testing facilitated transport membranes for CO 2 …”

“…Membrane technology has been actively used for many years for CO 2 separation in natural gas sweetening as it offers several advantages over other techniques including its environmental friendliness, lower capital cost, lower energy consumption, better space utility, and better suitability for applications in remote locations [1][2][3]. In this regard, fabrication of efficient membranes is the most important parameter in determining the advantageous nature and efficiency of this technology compared to other separation techniques.…”

Stability of blended polymeric materials for CO2 separation

“…Unfortunately these membranes still have relatively thick separation layers and thus low permeance of about 1 m 3 (STP)/(m 2 h bar). It should be mentioned that when using advanced coating techniques and membrane preparation conditions permeance can reach about 10 m 3 (STP)/(m 2 h bar) [19]. If active transport membranes would be stable against the post-combustion feed stream such membranes would be very competitive candidates for industrial separation systems.…”
