Modelling of carbon dioxide absorption in aqueous solutions of AMP and MDEA and their blends using Aspenplus

Solubilities of carbon dioxide in aqueous solutions of sodium glycinate

“…In our previous papers, we have reported the physical properties of SG solution and physical solubility and diffusivity of CO 2 in aqueous SG solution [21][22][23]. In continuation of this, we have measured the solubility of CO 2 in aqueous SG solutions of 10, 20, and 30 mass% at 303.15, 313.15, and 323.15 K over the pressure range (1-210 kPa) which would be utilized for the design, operation, and optimization of acid gas treatment equipment and also for measuring other chemical properties such as kinetic reaction, regeneration energy, and enthalpy of reaction [24][25][26][27][28][29][30][31][32].…”

The salt-based catalytic enhancement of CO2 absorption by a tertiary amine medium

“…It is well established that when CO 2 is exposed to tertiary amines bicarbonate is formed. [36][37][38] Bicarbonate formation was confirmed in the presence of the amine nitrate salts with 13 C NMR spectra. The 13 C NMR spectra of the mixtures of aqueous amine, a tertiary amine salt, and CO 2 contain peaks at 161 ppm for bicarbonate as a single product.…”

Economic analysis of amine based carbon dioxide capture system with bi-pressure stripper in supercritical coal-fired power plant

“…Despite its significance, the amine based CO 2 capture technology suffers from the huge energy consumption and large amine solution flow rate, which will result in significant increases in the cost of electricity (Davison, 2007). To compensate the heat penalty, researchers have carried out extensive studies on amine based CO 2 capture technology, but studies are mainly focused on chemical reaction mechanism, mass transfer, gas/liquid equilibrium and other related aspects (Alie et al, 2005;Aroonwilas et al, 2003;Goto et al, 2009;Aroua et al, 2002;Freguia and Rochelle, 2003). Tobiesen et al (2008) developed a numerical model for CO 2 desorption including desorber packing, reboiler and condenser.…”
