Abstract Scope A continuously looping solvent-based process using reversible physical interactions is favored for pre-combustion capture of CO2 from Integrated Gasification Combined Cycle (IGCC) power plants due to favorable partial pressures (20-30bar) of CO2 in the gas stream. Current state-of-the-art CO2 solvents such as Selexol™ often suffer from significant water affinity which results in the removal of large volumes of water from the pre-combustion fuel gas stream. This adsorbed water is needed as an energy-generation source in the combustion turbine. In addition, removal of adsorbed water results in an added energy penalty during the solvent regeneration step. We present here improved hydrophobic CO2 solvents which maintain a high CO2 adsorption affinity while minimizing the co-adsorption of H2O and H2. They are low viscosity, low cost, and environmentally friendly with high boiling points suitable for reactor operations at temperatures near 40C.
