Absorption of carbon dioxide into aqueous blends of 2-amino-2-methyl-1-propanol and diethanolamine

Process analysis on CO2 absorption by monoethanolamine solutions in microchannel reactors

“…Therefore, the main contributio n to the deprotonation of the zwitterion comes from MEA, and to a less extent from OH À , CO 2À 3 , HCO À 3 or H 2 O, since the deprotonat ion ability of a base mainly depends on its concentrat ion as well as how strong a base is [36].…”

Thermodynamics of CO2 Adsorption on Polyethyleneimine Mesoporous Silica and Activated Carbon

“…These techniques include different physical and chemical procedures including absorption, adsorption, membranes and cryogenics. Chemical absorption by liquid amines is the most applicable industrial technology for CO 2 scrubbing [4,5]. Several solid sorbents were also used.…”

“…So far, amines immobilized on mesoporous silica (MPS) have shown to have the highest CO 2 adsorptivity, high desorption rate, negligent corrosion problems, and low consumption of energy during regeneration [18,19]. Several amines supported mesoporous silica have been synthesized and studied [5,[9][10][11]15,18,20]. Furthermore, when high molecular weight polyethyleneimine (PEI) is employed the volatilization and/or decomposition are expected to be minimal because of the relatively high melting temperature of such a high molecular weight material.…”

Reactive Absorption of CO2 into Aqueous Mixtures of Methyldiethanolamine and Diethanolamine

“…Glasscock et al [4] presented experimental data for CO 2 absorption into mixed amine systems of MEA/MDEA using a batch liquid, continuous gas-stirred cell reactor. Blends of DEA/ AMP had been studied by Mandal et al [5] to absorb carbon dioxide. Absorption rates for CO 2 into aqueous blends of MEA/MDEA and MEA/TEA were reported by Rangwala et al [6] using a stirred cell.…”
