Kinetics of absorption of carbon dioxide into aqueous solutions of 2-amino-2-hydroxymethyl-1,3-propanediol

Separation of CO2 from the CO2/N2 mixed gas through ionic liquid membranes at the high feed concentration

“…The supported membrane was hydrophobic PVDF. The highest permeability of CO 2 The permeability of CO 2 increases with temperature for all the experimental conditions. The results of CO 2 /N 2 selectivity presented the opposite trends with permeability.…”

“…A number of researchers have attempted to separate CO 2 using many techniques such as adsorption [1], absorption [2], and membrane separation technology [3]. However, each method has some drawbacks such as cost of equipment and most adsorbents are highly expensive, require huge heating device for the adsorption method.…”

Physical Properties and Thermal Decomposition of Aqueous Solutions of 2-Amino-2-hydroxymethyl-1, 3-propanediol (AHPD)

“…The investigated solvent in this paper, 2-amino-2-hydroxymethyl-1,3-propanediol (AHPD) is also a sterically hindered amine [6,7]. The solubility data and kinetic studies show that AHPD is a good potential solvent for acid gas removal from industrial streams of interest [8][9][10][11].…”

Solubility and thermodynamic modeling of hydrogen sulfide in aqueous (diisopropanolamine+2-amino-2-methyl-1-propanol+piperazine) solution at high pressure

“…Thus, natural gas should be treated to remove these acid gases prior utilization [6][7][8]. The natural gas pipeline specifications usually limit the CO 2 and H 2 S content to less than 2% and 4 ppm, respectively [9]. The several processes such as physical and chemical absorption methods have been used in which among them the chemical solvents such as alkanolamines are widely used in the gas separation and purification technologies, because of highly reactive nature and low cost of these solvents [3].…”
