Performance comparison of pressure swing adsorption and amine‐based absorption for synthesis gas purification

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 5012-5027, September 2026.
Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.
