  • CARBON DIOXIDE REMOVAL FROM SYNTHESIS GAS AT ELEVATED PRESSURE
    Publication number: 20090293723
    Abstract: A method for removing CO2 from a pressurized gas stream with the effluent CO2 remaining at system pressure or higher is disclosed. Specifically, the removal method provides near isothermal absorption of CO2 from a gas stream in a suitable solvent at an elevated pressure and relatively low temperature. The solvent is then removed from contact with the gas stream, and the temperature is increased to such an extent that the CO2 will flash from the solvent.
