In order to start this research I opened up Google Scholar Search, typed in “CO2 separation” and received…. 2,160,000 results.
20,000 publications since beginning 2021 to-date alone!
In light of the sheer expansiveness of the subject matter we’re only skimming the surface in this Insight – nevertheless this introduction to post-combustion CO2 separation methods should serve as a solid foundation to build off of.
Separation of CO2 can be done by either chemical or physical means, and the 3 basic methods which are known to be effective are:
- Chemical – using Solvents / Sorbents
- Physical – Membrane separation
- Physical – Cryogenic separation
