Novel Solvent System for Post Combustion CO2 Capture
Project No.: DE-FE0005799

ION Engineering Ionic Liquid
ION Engineering Ionic Liquid

ION Engineering, LLC will conduct bench-scale testing of an amine-based solvent that employs an ionic liquid instead of water as the physical solvent, greatly reducing the regeneration energy while lowering process water usage. In addition to a 45 percent reduction in energy requirements (the need for stripping steam is eliminated, greatly reducing the energy penalty), an ionic liquid-amine solvent mixture offers higher CO2 working capacity, reduced corrosion, reduced solvent loss, smaller units with reduced capital costs, the ability to use lower quality steam in regeneration, and other benefits when compared to conventional aqueous amine solvents.
