Density measurements and modelling of loaded and unloaded aqueous solutions of MDEA (N-methyldiethanolamine), DMEA (N,N-dimethylethanolamine), DEEA (diethylethanolamine) and MAPA (N-methyl-1,3-diaminopropane)

Review on the mass transfer performance of CO2 absorption by amine-based solvents in low- and high-pressure absorption packed columns

“…[26][27][28] a tertiary-type amine, which is a potential candidate for CO 2 bulk removal. 34 This amine can be made from low-priced resources such as agricultural products and residues. 33 Kim and Savage, 35 Benitez-Garcia, et al 36 and Li, et al 37 have reported data of CO 2 absorption rates by DEEA at different temperatures and concentrations.…”

CO2 post combustion capture with a phase change solvent. Pilot plant campaign

“…Kim (2011) and Arshad et al (2013) reported heats of absorption data for this system and Ciftja et al (2013) showed speciation data based on NMR. Density data for loaded and unloaded single amine systems are reported in Pinto et al (2014a).…”

Density Calculations of Aqueous Amine Solutions Using an Excess Gibbs Based Model

“…Several attempts to model the density of a pure component have been used in the literature. Yang et al (2012) and Pinto et al (2014b) used a second order temperature polynomial model (Eq. 1), while Muhammad et al (2009) used a simple linear correlation (Eq.…”

“…temperatures was 42. Han et al (2012b) and Pinto et al (2014b), applied a temperature dependency on the regressed parameter and reduced the number of total parameters for the aqueous MEA systems to 8 and 6, respectively. Although the implementation of the temperature dependency drastically reduced the total number of estimated parameters, this number is still considered high for a binary system.…”
