CO₂ Absorption using MEA

Process model of CO₂ Absorption using MEA in DWSIM Pro.

In amine-based carbon capture processes, an amine solvent removes the CO₂ from gas streams. In an absorption column, the carbon dioxide is selectively removed from the gas stream. The CO2-rich solvent is heated and led to a desorption column where the amine solvent is regenerated and the CO2 is released to be send to storage or further processing.

This example shows the removal of CO2 from a mixture of hydrocarbons using Monoethanolamine (MEA) as a solvent. In order to provide an accurate prediction of physical properties and the reactive absorption in the Amine solution, the process is simulated using the Amines property package in DWSIM Pro.

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.
