Separation of CO₂ from Flue Gas: A Review

Capture of carbon dioxide from flue or fuel gas mixtures by clathrate crystallization in a silica gel column

“…Capture of CO 2 from power plant flue gases from conventional power plants or from fuel gases from gasification plants is a technological application of gas hydrates under consideration (Aaron and Tsouris, 2005;Kang and Lee, 2000;Klara and Srivastava, 2002;Kumar et al, 2009;Linga et al, 2008Linga et al, , 2007aSeo et al, 2005). Post-combustion CO 2 capture involves separation of CO 2 from the flue gas mixture emitted from a power plant.…”

Technical viability and exergy analysis of membrane crystallization: Closing the loop of CO2 sequestration

“…Several technologies and strategies are considered, depending on the application [2][3][4][5]. Both pre-combustion and postcombustion oriented technologies involve the separation of CO2 from a gas mixture, composed of CO2 and H2 in the first approach and CO2 diluted in air and other combustion gases, such as sulphur dioxide or nitrogen oxides, in post-combustion.…”

Polyethyleneimine functionalised nanocarbons for the efficient adsorption ofcarbon dioxide with a low temperature of regeneration

“…[7] There are several different types of membranes in development for the capture of CO 2 , [5] as well as cryogenic distillation, which is an energy intensive process. [8] The best present commercial process for the large-scale capture involves monoethanolamine (MEA), which is an aqueous-based capture technique generally composed of a 30% solution of MEA in water. The CO 2 source is passed through a liquid amine to form a carbamate (Equation (1)), among other possible species.…”
