Flow of the Standard Process

The flue gas blower feeds flue gas from the plant stack to the KM CDR Process^®. After cooling in the flue gas cooler to a temperature of 45 degrees centigrade or lower, the flue gas is fed into the bottom section of the absorber and upward through the packing material inside the tower. As the flue gas passes through the material, the KS-1™ solvent is distributed evenly from the top of the absorber onto the packing material, allowing the solvent to selectively capture the CO₂ from the gas. Next, the KS-1™ solvent with the captured CO₂, "CO₂-rich solution", is collected in the bottom section of the absorber, heat exchanged, and pumped into the stripper from the upper section. Once within the stripper, the CO₂-rich solution is distributed onto a strip of internal packing placed in contact with an upward stream of stripping-steam produced by the reboiler. This steam strips the CO₂ from the CO₂-rich solution at the stripper, yielding CO₂ with a high purity of 99.9 vol. percent or more at 1.6 barA (Dry Base). At the final stage, the stripped lean solution is cooled down and reintroduced into the absorber through the heat exchanger and cooler.
