Thermodynamic modeling of MDEA(aq)-NH3(aq)-K2CO3(aq)-CO2(aq) using the Extended UNIQUAC model

Using Reaktoro for mineral and gas solubility calculations with the Extended UNIQUAC model

“…▪ Prediction of thermal properties and phase behavior of aqueous electrolyte systems (Thomsen et al, 1996). Over the past almost four decades, the extended UNIQUAC model has been further enhanced, extended, parameterized, and applied to various aqueous electrolyte systems and engineering applications (Aronu et al, 2011;Arrad et al, 2016Arrad et al, , 2017Arshad et al, 2016Arshad et al, , 2017Awan et al, 2010;Barzegar-Jalali et al, 2020;Bonalumi et al, 2016;Chakravarty et al, 2015bChakravarty et al, , 2015aChokradjaroen et al, 2012;Christensen & Thomsen, 2003Corrêa et al, 2023;Corrêa, Hao, et al, 2022;Darde et al, 2009Darde et al, , 2011Darde, Maribo-Mogensen, et al, 2012;Eftekhari et al, 2017;Faramarzi, Kontogeorgis, et al, 2009;Faramarzi, Kontogorgis, et al, 2009;Figueroa et al, 2016;Fosbøl et al, 2009aFosbøl et al, , 2009bFosbøl et al, , 2013García et al, 2005bGarcía et al, , 2006bGaspar, Arshad, et al, 2014;Gaspar et al, 2016;Gomis et al, 2022;Haghtalab & Peyvandi, 2012;Hashemi et al, 2020;Hingerl et al, 2014;Iliuta et al, 2000Iliuta et al, , 2002Kontogeorgis et al, 2022;Kovalenko et al, 2011;…”

“…▪ Solubility calculation of BaSO 4 in water at high-pressure and high-temperature conditions, up to 350 bar and 440.1 K, (Shi et al, 2023b); and in aqueous solutions at various temperatures and concentrations of chlorides NaCl, KCl, MgCl 2 , and CaCl 2 , and nitrates NaNO 3 and KNO 3 (Shi et al, 2023a). ▪ Carbon capture modeling in mixed solvent solutions containing CO 2 , MDEA, NH 3 , and K 2 CO 3 at wide range of temperatures and pressures (Corrêa et al, 2023). ▪ Modeling aqueous systems involving terephthalic acid, disodium terephthalate, sodium chloride, sodium hydroxide, and ethylene glycol (Rezazadeh et al, 2022).…”
