Abstract
A COamine scrubbing process uses an absorbent mixture combination of an amine containing a primary amino group COsorbent in combination with a non-nucleophilic relatively stronger base. The weaker base(s) are nucleophilic and have the ability to react directly with the COin the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the COand the weaker base. Two moles of COcan be taken up by the primary amine groups in a dicarboxylation reaction, affording the potential for a highly efficient scrubbing process.
