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.

The mixtures of propylene carbonate (PC) (1) + poly(propylene glycol) monobutyl ether with a molecular weight of 340 (PPGME340) (2) were studied as physical absorbents for CO2 absorption with different mass fractions (w 1 = 0.0000, 0.2501, 0.5002, 0.7495, and 1.0000). The physical properties including densities and kinematic viscosities of these absorbents were determined and regressed by linear equation and Vogel–Fulcher–Tammann equation. CO2 absorption capacities of the absorbents under pressures up to 1300 kPa and at temperatures from 298.15 to 303.15 K were determined by the isothermal synthesis device and fitted by the extended Antoine equation. Adding PC into PPGME340 will result in a slight increase of density, dramatic decrease of kinematic viscosity, and moderate decrease of CO2 absorption capacity based on per mole absorbent. Compared with common solvents in industrial plants, PPGME340-contained absorbents show relatively high absorption capacity and kinematic viscosity. In addition, absorbent PC + PPGME340 with a mass fraction of w 1 = 0.2501 shows relatively high CO2 absorption capacity and moderate kinematic viscosity, suggesting its better potential for the industrial application than pure PPGME340.

“…For example, the use of hybrid solvents, containing amine solutions and physical solvents, may improve the efficiency of the current amine absorption processes. Hybrid solvents couple the properties of solvents to take advantage of favorable aspects of solvents while minimizing the disadvantages. , In recent years, ionic liquids (ILs), which are nonvolatile and recyclable solvents, ,,− have been investigated as blends with amines and other physical solvents for carbon dioxide capture. − ,,− Lei et al showed that addition of omim[TF 2 N] to methanol at a temperature of 313.2 K and pressures between 2 and 6 MPa increases the CO 2 solubility in comparison to pure methanol .

Alkanolamine solutions are used in the industry worldwide to remove carbon dioxide and hydrogen sulfide from natural gas, but such technologies have disadvantages. This study aimed to investigate the new hybrid amine solvents for carbon dioxide capture and their potential to reduce the disadvantages of amine technology. The solubility of carbon dioxide in hybrid solvents with different mixtures of monoethanolamine, water, n-methyl-2-pyrrolidone, 1-butyl-3-methylimidazolium trifluoromethanesulfonate, and 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide was measured at temperatures of 298.15 and 313.15 K by a static synthetic method. The viscosity, density, speed of sound, and evaporation rates for the hybrid solvents were also measured. Experimental observations indicate that the solubility of carbon dioxide in a hybrid solvent of n-methyl-2-pyrrolidone + monoethanolamine was greater than that of the aqueous amine solvent, except at low pressures depending on the concentration of amine. The addition of an ionic liquid to the amine solution reduced the volatility of the solvent and decelerated the evaporation rate of amine, while the loss of ionic liquid was almost zero. However, the addition of an ionic liquid to n-methyl-2-pyrrolidone-containing monoethanolamine solvent or the aqueous monoethanolamine solvent decreased the solubility of carbon dioxide and increased the viscosity of the solution.
