摘要:
The present invention relates to a carbon dioxide absorbent comprising an oxygen-containing diamine, a cyclodiamine, and a polyalkylene glycol dialkyl ether. The carbon dioxide absorbent according to the present invention can improve the carbon dioxide absorbing ability, absorption rate, and reproducibility thereof at the same time by using the oxygen-containing diamine as a main absorbent, the cyclodiamine as a rate enhancer, and the polyalkylene glycol dialkyl ether as a fine disproportionation agent and a reproduction promoter.
摘要:
A method and plant for capturing CO 2 from a CO 2 containing exhaust gas (1), where the exhaust gas is compressed (10) and thereafter cooled (13, 15, 22) before the exhaust gas is introduced into an absorber (30), where the exhaust gas is brought in counter-current flow with an aqueous CO 2 absorbent solution (49), to give a lean exhaust gas (31) that is withdrawn from the absorber (30), reheated 22, 13) against incoming compressed exhaust gas, and thereafter expanded (34) and released into the atmosphere (4), where the aqueous CO 2 absorbent solution is an aqueous potassium carbonate solution, and that the steam and CO 2 withdrawn from the regenerator (40) is cooled in a direct contact cooler (61) by counter-current flow of cooling water (62), to generate a gaseous flow (70) of cooled CO 2 and steam that is withdrawn for compression and drying of the CO 2 , and a liquid flow (64) of cooling water and condensed steam that is withdrawn and flashed (80), to give a cooled liquid phase (84) that is recycled as cooling water for the direct contact cooler (61) for the withdrawn CO 2 and steam, and a gaseous phase (81) that is compressed (82) and thus heated, and introduced into the regenerator (40) as stripping steam (83).

摘要:
AA 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.
