Mixed Amine and Non-Nucleophilic Base CO2 Scrubbing Process for Improved Adsorption at Increased Temperatures

ActiveUS20120060686A1Adjust pressure stabilityAdjust temperature stabilityDispersed particle filtrationCarbon compoundsNon-nucleophilic baseDesorption
A CO2 amine scrubbing process uses an absorbent mixture combination of an amine CO2 sorbent in combination with a non-nucleophilic, relatively stronger, typically nitrogenous, base. The weaker base(s) are nucleophilic and have the ability to react directly with the CO2 in the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the CO2 and the weaker base. The sorption and desorption temperatures can be varied by selection of the amine / base combination, permitting effective sorption temperatures of 70 to 90° C., favorable to scrubbing flue gas.
