Carbon Dioxide (CO2) Absorption Solvents Services
Solvent absorption is currently considered to be the best method for removing carbon dioxide, CO2, from power plant flue gases. The absorption solvent must balance high affinity for CO2 with the ability to release CO2 under certain conditions. In addition the solvent must be non-toxic, low cost, thermally and chemically stable, safe and have a low environmental impact.
MKS Contribution: In collaboration with researchers from the Electric Power Research Institute (EPRI) we developed detailed thermodynamic models for the absorption of carbon dioxide into candidate solvents. We then used the group contribution techniques and other estimation techniques found in Cranium to computationally screen candidates solvents. The properties of the most promising solvents were estimated and then exported to a chemical process simulator to evaluate performance.
