Cardo polyimide membranes for CO2 capture from flue gases

Membrane-based carbon capture from flue gas: a review

“…They noticed that Cardo polyimide (PI-BT-COOMe), having a CO 2 affinitive methylcarboxyl functional group, shows outstanding CO 2 /N 2 selectivity behavior. More specifically, Cardo polyimides which had 3,3 0 ,4,4 0 -Benzophenonetetracarboxylic dianhydride as a monomer (PI-BT) obtained the highest separation with CO 2 /N 2 selectivity of 52 at 25 C. Later, it was reported that a bis(phenyl)fluorene-based Cardo polyimide could result in membranes with notably high permeance of 1000 GPU with good CO 2 /N 2 selectivity of 40 (Kazama et al, 2004). Yoshino et al (2000) studied the effects of hard-segment polymers (namely polyurethanes (PUs), polyamides (PAs), and polyamides (PIs)) on CO 2 /N 2 separation properties of poly(ethylene oxide) (PEO).…”

“…Schematic of one-stage enriching with two-stage stripping. Kazama et al (2004) carried out an economic analysis to evaluate their developed Cardo polyimide hollow fiber membrane with high CO 2 permeance of 1000 GPUs and CO 2 /N 2 selectivity of 40. They illustrated that the success of membranes as an alternative to existing amine-based capture systems depends on the CO 2 concentration of source gases.…”

Techno-economic study of CO2 capture from natural gas based hydrogen plants

“…This enhanced technology could lead to a better energy consumption and cost-effective method in capturing CO 2 . One of the recent membrane material developed is the cardo polyimide hollow fibre membranes [Kazama, et al, 2004].…”

Polymeric membranes composed of polystyrenes tethering amino acids for preferential CO2 separation over H2

“…Since, CO 2 capturing or separation has dominated the major part of the cost [4], development of an effective CO 2 separation is of now a key in the CCS. Among various separation techniques, membrane separation with polymeric materials would be one of the promising approaches in terms of less energy consumption, technological and economic perspectives [5]. A number of investigations have been studied to separate CO 2 from other organic and inorganic gases, which were mostly larger than CO 2 [6][7][8].…”
