An overview of CO2 capture technologies
Niall MacDowell,Nick Florin,Antoine Buchard,Jason P. Hallett,Amparo Galindo,George Jackson,Claire S. Adjiman,Charlotte K. Williams,Nilay Shah,Paul S. Fennell +9 more
TL;DR: Three of the leading options for large scale CO2 capture are reviewed from a technical perspective, including solvent-based chemisorption techniques, carbonate looping technology, and the so-called oxyfuel process.
Journal ArticleDOI
The outlook for improved carbon capture technology
TL;DR: In this paper, the authors assess the outlook for improved, lower-cost technologies for each of the three major approaches to CO2 capture, namely, post-combustion, precombustions, and oxy-completions, along with the current status of projects and processes at various stages in the development cycle.

CO2 Capture by Tertiary Amine Absorbents: A Performance Comparison Study
TL;DR: In this article, the authors investigated CO2 capture with 24 tertiary amine absorbents, including three synthetic amines, with systematic modification of their chemical structures, and compared them with the conventional tertiary absorbent N-methyldiethanolamine.
Journal ArticleDOI
Highly Efficient and Reversible SO2 Capture by Tunable Azole-Based Ionic Liquids through Multiple-Site Chemical Absorption
TL;DR: These tunable azole-based ionic liquids with multiple sites with high capacity and excellent reversibility offer significant improvements over commonly used absorbents, indicating the promise for industrial applications in acid gas separation.
Journal ArticleDOI
Aqueous amine solution characterization for post-combustion CO2 capture process
TL;DR: In this article, a solvent screening setup was used to find the CO 2 loading (α ) for 30 different aqueous amine solutions (30wt%) at a pressure of 1 bar with feed gas containing 15% CO 2 and 85% N 2 at 313.15, 303.15 and 313.9 K to provide reliable absorber parameters, and the combined data for the CO2 loading and the absorption heat generated 6 amines that have good properties for the post-combustion CO 2 capture process in comparison with that of MEA.

TL;DR: In this article, the process for CO2 removal from flue gases was modeled with RateFrac, which consists of an absorber, a stripper, and a cross heat exchanger.
Journal ArticleDOI
Alternative stripper configurations for CO2 capture by aqueous amines
TL;DR: In this paper, four new stripper configurations (matrix, internal exchange, flashing feed, and multipressure with split feed) have been evaluated with seven model solvents that approximate the thermodynamic and rate properties of 7m (30 wt %) monoethanolamine (MEA), potassium carbonate promoted by piperazine (PZ), promoted MEA, methyldiethanolamine (MDEA) promoted by PZ, and hindered amines.
Journal ArticleDOI
Energy performance of stripper configurations for CO2 capture by aqueous amines
TL;DR: In this paper, a simple stripper operating at 160 kPa, a multipressure stripper at three pressures (330/230/160 kPa), and a vacuum stripper (30 kPa) for two solvents: 7m (30 wt %) monoethanolamine (MEA) and 5m K+/2.5m piperazine.
Journal ArticleDOI
Enthalpy of absorption of CO2 with alkanolamine solutions predicted from reaction equilibrium constants
TL;DR: In this paper, the Gibbs-Helmholtz equation was used to predict enthalpies of absorption of CO 2 in aqueous solutions of 2-aminoethanol (MEA) and N-methyldiethanolamine.
