Honeywell UOP’s CO₂ Fractionation system uses temperature and pressure controls, along with proprietary refrigerants, to capture CO₂ as a high-purity liquid product. The process is electrically driven with reduced equipment count and plot area compared to amine solvent solutions. It is ideal for applications like steam-methane reforming with medium or high CO₂ concentration.

CO₂ Fractionation has been commercially demonstrated with more than 400 units operating in gas processing applications around the world.
