REDUCTION OF AMINE EMISSIONS FROM AN AQUEOUS AMINE CARBON DIOXIDE CAPTURE SYSTEM USING CHARGED COLLOIDAL GAS APHRONS

摘要

The present invention includes a system and process to reduce amine mist emissions (or MEA) from carbon capture systems using colloidal gas aphrons (CGA), and includes a method for separating and recovering an amine solvent (e.g., in the form of entrained droplets/mist and/or fine aerosol particles) from a carbon dioxide scrubbed flue gas stream exiting a carbon capture system (e.g., oil-fired power plants, coal-fired power plants, and/or natural gas combined cycle plants).

主权项

1. A system for removing amine solvents from a carbon capture flue gas comprising:
a generator cell comprising a stirrer and a measure of surfactant in a solution to generate colloidal gas aphrons (CGAs); a capture cell comprising a medium and an inlet for CGAs and an outlet for flue gas at a first end of the capture cell and an outlet for CGAs and an inlet for flue gas at a second opposite end of the capture cell; and an eliminator cell with an inlet port to receive CGAs from the outlet for CGAs from the capture cell.
