The Use of a Monoethanolamine (MEA) Solvent for Carbon Capture

Published on 5 March 2025 at 21:17

In this post I will reviewing another method of carbon capture other than an algae bioreactor. A Monoethanolamine (MEA) solvent is another project which focuses on the capture of carbon emissions. It intends to capture the CO2 from diesel ovens and the flue gas exhausted by the power plant in order absorb pure CO2 and store it.

Here are some notes about the MEA solvent process:

  1. Flue gas enters a chamber
  2. MEA absorbs CO2
    • Gas moves upwards as the liquid MEA solution moves downward forming the carbamate intermediate
    • The leftovers (Nitrogen and Oxygen) is then released
  3. Regeneration
    • The CO2-MEA solution is heated inside a stripper
      • Heat breaks the bond releasing pure CO2
    • The MEA solution is cooled and recycled back to use again
  4. CO2 storage
    • The pure CO2 is dried and compressed
    • Storage: can be injected deep underground (Carbon Capture and Storage CCS)
    • Can be used: for enhanced oil recovery (EOR), making synthetic fuels, or in the food/drink industry (carbonation of drinks)

 

Thank you for tuning in and a new post is coming next month!
