Physical absorption (high value chemicals)


Technology Description

Physical absorption uses a liquid solvent to absorb CO2 from flue gases that have high CO2 partial pressures, without a chemical reaction occurring. Common physical solvents include Selexol (dimethyl ethers of polyethylene glycol) and Rectisol (methanol).

Relevance for Net Zero

CCS has good potential to reduce emissions from high value chemicals (HVCs) production at a reasonable cost. It is a key competitor for emission reductions for HVCs.
