Desorption with chemical reaction in the system CO2-aqueous solution of potassium carbonate

Particularities of Membrane Gas Separation Under Unsteady State Conditions

“…are the only volatile species; a negligible change in the liquid phase volume during absorption of volatile components; concentration of volatile components in molecular form in the membrane and the liquid phase obeying Henry's law. The approach of CO 2 interaction with aqueous potassium carbonate can be found in numerous studies (Cents et al, 2005;Chen et al, 1999;Danckwerts & Sharma, 1966;Dindore et al, 2005;Lee et al, 2001;Morales-Cabrera et al, 2005;Otto & Quinn, 1971;Pohorecki & Kucharski, 1991;Suchdeo & Schultz 1974;Ward & Robb, 1967 Theoretical and experimental dependencies are almost identical for the LM with distilled water (Fig. 18) and the time of unsteady CO 2 transfer is about 30 seconds.…”

CO2 capture with potassium carbonate solutions: A state-of-the-art review

“…They investigated the effects of carbonate conversion and amine concentration on the CO 2 -DEA reaction kinetics. Pohorecki and Kucharski (1991) measured the rate of desorption of CO 2 (kinetic reaction rate constants) and equilibrium constant for PC solution in the temperature range 333-373 K and ionic strength of solution in the range 2-8 mol/dm 3 . They also developed a method of absorption and desorption rates estimation for the PC system in industrial scale based on the results obtained in the study.…”

Gas-liquid membrane contactors for carbon dioxide separation: A review

“…Potassium carbonate (K2CO3) is a further example of an electrolyte that has been commercially used for CO2 removal in ammonia and methanol manufacturing, as well as acidic gas removal from ammonia syngas, crude hydrogen, natural gas [47,48]. The K2CO3 based absorption system, called the Benfield process, is advantageous as the species is non-volatile, has high CO2 solubility, is cheap, non-toxic and does not degrade.…”
