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.
As renewable electricity prices continue to diminish, interest grows in alternative routes for the synthesis of sustainable fuels and chemicals, including ammonia. Considering demand for fertilizers, as well as for...
The dissociation constants of the
conjugate acids of 14 amines
(diethylethanolamine, monoethanolamine, n-butyldiethanolamine, t-butyldiethanolamine, n,n-dimethylpropanolamine, methyl-diethanolamine, ethyldiethanolamine,
monoethylethanolamine, n,n-dimethylisopropanolamine,
triethanolamine, 4-methylpiperazine-1-amine, 3-morpholino propylamine,
4,2-hydroxylethylmorpholine, and triethylamine) were measured over
a temperature range between 293.15 and 333.15 K using the potentiometric
titration method. The change in standard state thermodynamic properties
was derived from the van’t Hoff equation. The influence of
the steric hindrance, number of −OH groups, and length of alkyl
chain on the dissociation constants was identified. Of the studied
amines, few sterically hindered derivatives of piperazine, a secondary
amine monoethylethanolamine, and a tertiary amine n,n-dimethylpropanolamine have high pK
a values but lower standard enthalpy than those of the
benchmark amine, monoethanolamine (MEA), and thus were deemed promising
for CO2 capture technology. Monoethylethanolamine (MEEA)
was found to have the highest basicity (pK
a) with the lowest standard state enthalpy (ΔH°/kJ·mol–1).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
