Rigorous modeling of CO2 absorbers using potassium carbonate solutions

As part of the global campaign to reduce CO2 emissions, carbon capture and reduction are receiving increased attention from a variety of process industries, especially power generation and oil and gas exploration and production.

As part of the global campaign to reduce CO2 emissions, carbon capture and reduction are receiving increased attention from a variety of process industries, especially power generation and oil and gas exploration and production. One way to capture carbon is to remove the CO2 from flue gas resulting from the combustion of fossil fuels. The hot potassium carbonate (HPC) process is one of the major commercialized processes for CO2 removal. Potassium carbonate has been used as the absorption solvent to remove CO2 from flue gas for more than 70 yr. At present, there are two commercialized technologies for CO2 removal with HPC aqueous solutions: the Benfield and CATACARB processes. The Benfield p
