Abstract: A system for carbon dioxide capture from a gas mixture comprises an absorber that receives a lean solvent system stream (containing a chemical solvent, physical-solvent, and water) from the stripper, a stripper that receives the rich solvent stream from the absorber and produces the product carbon dioxide and the lean solvent through the use of a reboiler in fluid communication with a lower portion of the stripper, a condenser in fluid communication with a vapor outlet of the stripper, a cross-exchanger in fluid communication with a rich solvent system outlet from the absorber and a rich solvent system inlet on the stripper, and a splitter. The splitter is configured to separate the rich solvent system stream into a first portion and second portion, where the first portion directly passes to the stripper and the second portion passes through the cross-exchanger prior to passing to the stripper.

Abstract: A system for carbon dioxide capture from a gas mixture comprises a lean solvent comprising 3-amino-1-propanol (AP), 2-dimethylamino-2-methyl-1-propanol (DMAMP), and water; an absorber containing at least a portion of the lean solvent, wherein the absorber is configured to receive the lean solvent and a gaseous stream comprising carbon dioxide, contact the lean solvent with the gaseous stream, and produce a rich solvent stream and a gaseous stream depleted in carbon dioxide; a stripper, wherein the stripper is configured to receive the rich solvent stream; a cross-exchanger fluidly coupled to a rich solvent outlet on the absorber and a rich solvent inlet on the stripper; a reboiler fluidly coupled to a lower portion of the stripper; and a condenser fluidly coupled to a vapor outlet of the stripper.

Abstract: Systems and processes for reducing carbon capture emissions are described. The process involves introducing a radical species into a decarbonized combustion gas. The radical species react with residual amines or unwanted compounds in the decarbonized combustion gas, thus reducing the concentration of residual amines or unwanted compounds in the exhaust gas. The system includes a carbon capture absorber with non-thermal plasma generator configured to provide radical species reducing the concentration of residual amines or unwanted compounds in the exhaust combustion gas.
