Solubilities of carbon dioxide in aqueous solutions of sodium glycinate

Characterization of potassium glycinate for carbon dioxide absorption purposes

“…Holst et al (2006) compared the apparent absorption rate constants of CO 2 with different amino acid salt solutions and concluded that they were comparable with alkanolamines. Recently Lee et al studied the physical properties and the absorption kinetics of sodium glycinate as an absorbent of carbon dioxide (Lee et al, 2005(Lee et al, , 2007Song et al, 2006). However, the data available in literature are still too limited to permit a suitable design and optimization of processes using amino acid absorbents.…”

Solubility of CO2 in aqueous TSP

“…4 that CO 2 solubility increased continuously as the temperature was increased at the fixed CO 2 partial pressure and total TSP concentration. TSP is less soluble [28] at lower temperature and more and more dissolution of TSP is occurred at higher temperatures which favors higher absorption of CO 2 from the gas stream. As temperature increases more and more TSP is available in the liquid as dissolved form which is responsible to capture more CO 2 from bulk of the gas to the liquid and thereby increases the CO 2 solubility in the liquid.…”

Equilibrium solubility, density, viscosity and corrosion rate of carbon dioxide in potassium lysinate solution

“…The study showed a decrease in loading capacity with an increase in amino acid salt concentration. They discovered that CO 2 solubility in 10 mass% sodium glycinate solutions was better than other aqueous absorbents such as MEA, 2-amino-2-ethyl-1,3-propanediol (AEPD), 2-amino-2-ethyl-1,3-propanediol (AMPD), and Triisopropanolamine (TIPA) [18]. Munoz et al investigated the absorption of CO 2 into 1 M solution of the potassium salts of glycine, taurine, proline, threonine, serine, histidine, arginine and ornitine.…”
