“…The equilibria are very sensitive to temperature because the reaction constants K shift with temperature (Jakobsen et al, 2005). Under constant temperature, the concentration of anions did not change at certain CO 2 loading.…”

“…Voice et al (2013) reported that the cyclic capacity of aqueous 8 M 3-(methylamino) propylamine (MAPA) was lower than that of 7 M MEA (0.42 vs. 0.79). At CO 2 partial pressure of 0.1 kPa and 40 • C, the loadings for MEA, 3-amino1-propanol (3A1P), 4-amino-1-butanol and 5A1P are 0.38, 0.41, 0.42 and 0.44, respectively, indicating slight increase in CO 2 solubility with the number of carbon atoms in the chain of the alkanolamines (Idris et al, 2015).…”

“…The ion speciation with the exact concentrations of cations, free molecules, and anions in the solvent under different CO 2 loadings are of research interest. Ion speciation plots can provide an important database for CO 2 absorption (20-40 • C) (Fan et al, 2009;Holmes et al, 1998;Jakobsen et al, 2005) and regeneration (90 • C) (Shi et al, 2014a). It can be detected experimentally with NMR spectroscopy combined with other equilibrium methods.…”

“…Most researchers have applied a pH meter with NMR technology to detect the ion speciation of amine-CO 2 -H 2 O systems (Holmes et al, 1998;Jakobsen et al, 2005). The pH measurement is used to determine the amount of two species appearing as a common peak, such as amine/amine H+ or bicarbonate and carbonate.…”

“…The pH meter tests the concentration of [H + ] in order to detect the free amine (Am) and protonated amines (AmH + ) with deprotonation constant K while the NMR instrument tests the carbamate, bicarbonate, and carbonate. NMR is effective in ion concentration testing due to several advantages: the specific ions possess their own chemical shifts both in 1 H and 13 C NMR spectra (Fan et al, 2009;Holmes et al, 1998;Jakobsen et al, 2005). Holmes et al (1998) performed NMR analysis of NH 3 -CO 2 -H 2 O systems with both 1 H and 13 C spectra.…”

Greenhouse Gas Control (2015), http://dx.Keywords: Recent development of PCC process Design and modeling Solvent development Post Build Operations Solvent chemistry Solvent management Mass transfer with reaction a b s t r a c tCurrently, post-combustion carbon capture (PCC) is the only industrial CO 2 capture technology that is already demonstrated at full commercial scale in the TMC Mongstad in Norway (300,000 tonnes per year CO 2 captured) and BD3 SaskPower in Canada (1 million tonnes per year CO 2 captured). This paper presents a comprehensive review of the most recent information available on all aspects of the PCC processes. It provides designers and operators of amine solvent-based CO 2 capture plants with an in-depth understanding of the most up-to-date fundamental chemistry and physics of the CO 2 absorption technologies using amine-based reactive solvents. Topics covered include chemical analysis, reaction kinetics, CO 2 solubility, and innovative configurations of absorption and stripping columns as well as information on technology applications. The paper also covers in detail the post build operational issues of corrosion prevention and control, solvent management, solvent stability, solvent recycling and reclaiming, intelligent monitoring and plant control including process automation. In addition, the review discusses the most up-to-date insights related to the theoretical basis of plant operation in terms of thermodynamics, transport phenomena, chemical reaction kinetics/engineering, interfacial phenomena, and materials. The insights will assist engineers, scientists, and decision makers working in academia, industry and government, to gain a better appreciation of the post combustion carbon capture technology.
