CO₂ Absorption using MEA
Process model of CO₂ absorption using MEA in DWSIM Pro.
Carbon Capture stands for processes that allow to reduce CO₂ emissions by capturing the CO₂ at the emission sources.
One of the known process solutions is the Amine-based carbon capture which uses an amine solvent to remove CO₂ from, e.g., flue gas.
Amines Property Package in DWSIM Pro
The Amines Property Package in DWSIM Pro provides an integrated solution for simulating amine-based processes. It can be applied for a wide range of carbon capture processes, among them gas sweetening, power plant post carbon-capture and biogas scrubbing.
Features:
- All chemical reactions that occur in the alkanolamine solution are considered within the property package. There is no need to define any reactions for the absorption or desorption.
- You can model the simultaneous capture of H₂S and CO₂
- You can simulate a variety of solvents (MEA, MDEA, DEA and Piperazine), as well as mixtures of amines.
- The model is validated in a broad operating range:

- The simulation provides key parameters, like CO₂ and H₂S Loading, CO₂ partial pressures and the pH of the amine solution .
- You can run comprehensive sensitivity analyses, create charts and export results to Excel to analyze key parameters, like the liquids CO₂ Loading after the absorption, in your simulation:
2-dimensional sensitivity analysis to investigate the CO₂ Loading after the absorption column for different CO₂ partial pressures in the Gas Inlet.
