“…Over the past decades, many emerging process configurations have been developed to reduce the energy consumption and capital cost for CO 2 capture. The absorber coupled with an intercooler (i.e., intercooling) can lower absorption temperature and enhance absorption capacity due to a new thermodynamic equilibrium being reached (Chang and Shih, 2005;Karimi et al, 2011;Kvamsdal et al, 2009;Oexmann et al, 2008;Plaza et al, 2010). However, it should be noted that the lower temperature will decrease the CO 2 absorption rate.…”

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.

“…Strategies to reduce the penalty associated with post-combustion CO 2 capture by amine scrubbing include improvements in the process configurations (Ahn et al, 2013;Jung et al, 2013;Karimi et al, 2011), the development of solvents with a better performance (Hoff et al, 2013;Mathias et al, 2013;Trollebø et al, 2013) and heat integration between the capture and the power plants (Liebenthal et al, 2013;Sipöcz et al, 2011). In the field of solvent development, the aim is to find a solvent that gives an optimal trade-off between fast kinetics and low energy requirements.…”

“…It was concluded that cooling to 40 • C was found to have the maximum effect on reboiler duty and also minimization of additional equipment. Karimi et al [7] investigated the intercooling effect in CO 2 capture energy consumption, the optimal location for intercooling was about 1/4th to 1/5th of the height of the column from the bottom which brought about 2.84% savings in reboiler energy and it was concluded that intercooling is an option for reducing energy consumption. Aroonwilas and Veawab [8] modelled an intercooler configuration which has been integrated with an amine process to evaluate the energy savings effect as a result of enhanced working capacity.…”

This paper presents steady-state simulation and exergy analysis of the 2-amino-2-methyl-1-propanol (AMP)-based post-combustion capture (PCC) plant. Exergy analysis provides the identification of the location, sources of thermodynamic inefficiencies, and magnitude in a thermal system. Furthermore, thermodynamic analysis of different configurations of the process helps to identify opportunities for reducing the steam requirements for each of the configurations. Exergy analysis performed for the AMP-based plant and the different configurations revealed that the rich split with intercooling configuration gave the highest exergy efficiency of 73.6%, while that of the intercooling and the reference AMP-based plant were 57.3% and 55.8% respectively. Thus, exergy analysis of flowsheeting configurations can lead to significant improvements in plant performance and lead to cost reduction for amine-based CO2 capture technologies.
