“…The kinetics of CO 2 absorption into aqueous solution of tertiary amine (e.g., TEA and MDEA) have been studied by Benitez-Garcia et al (1990), Haimour et al (1987), and Yu et al (1985). They have found that the reaction order with respect to the tertiary amine concentration is 1, which is in good agreement with the base catalyzed hydration mechanism.…”

Please cite this article in press as: Liang, Z., et al., Recent progress and new developments in post-combustion carbon-capture technology with amine based solvents. Int. J. 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.

“…Meanwhile, Silva and Svendsen also reported the Brønsted relationships of some amine solvents. In this work, the Brønsted plots for eight tertiary amines (Triethanolamine(TEA), MDEA, Dimethylmonoethanolamine (DMMEA), DEMEA (diethylmonoethanolamine), 1-dimethylamino-2-propanol(1DMA2P), triethylamine (TREA), 4-(diethylamino)-2-butanol (DEAB) and 1-(2-HE)PP were developed for the temperature range of 298–313 K, ,,,,,− and are shown in Figure . According to the work of Versteeg and van Swaaij, the kinetics of tertiary amine absorption CO 2 was related to the p K a value in that the higher the p K a , the faster the reaction kinetics.…”

In this present work, the absorption kinetics of CO2 into aqueous 1-(2-Hydroxyethyl) piperidine (1-(2-HE)PP) solutions with respect to observed pseudo-first-order rate constant (k 0) and second order reaction rate constant (k 2), were determined using the stopped-flow apparatus within the 1-(2-HE)PP concentration range of 0.20–1.00 kmol/m3 and a temperature range of 293–313 K. The values of k 0 were then represented using the correlation based on the base-catalyzed hydration mechanism. The results show that the correlated values of k 0 matched well with the experimental values with an acceptable AAD of 8.3%, which indicates that the base-catalyzed hydration mechanism can satisfactorily describe the experimental kinetics data of the1-(2-HE)PP reaction with CO2. In order to comprehensively understand the kinetics, the ion speciation plots of 1-(2-HE)PP-H2O–CO2 system were developed using the pH method. In addition, the Brønsted plots between k 2 (obtained from stopped-flow apparatus) and pK a (obtained from experimental measurement) for 1-(2-HE)PP were developed, and then used to predict k 2 using the values of pK a.

“…In our previous papers, we have reported the physical properties of SG solution and physical solubility and diffusivity of CO 2 in aqueous SG solution [21][22][23]. In continuation of this, we have measured the solubility of CO 2 in aqueous SG solutions of 10, 20, and 30 mass% at 303.15, 313.15, and 323.15 K over the pressure range (1-210 kPa) which would be utilized for the design, operation, and optimization of acid gas treatment equipment and also for measuring other chemical properties such as kinetic reaction, regeneration energy, and enthalpy of reaction [24][25][26][27][28][29][30][31][32].…”
