US 2025/0025831 A1 · SYSTEM AND PROCESS OF CAPTURING CARBON DIOXIDE FROM FLUE GASES

Abstract

A system and a process for capturing Carbon Dioxide (CO2) from flue gases are disclosed. The process comprises feeding a flue gas comprising CO2 to at least one Rotary Packed Bed (RPB) absorber rotating circularly. A solvent may be provided through an inner radius of the RPB absorber. The solvent may move towards an outer radius of the RPB absorber. The solvent may react with the flue gas in a counter-current flow. The process further includes passing the flue gas through at least one of a water wash and an acid wash to remove traces of the solvent present in the flue gas. Finally, the solvent reacted with the CO2 may be thermally regenerated for re-utilizing the solvent back in the process.

Dependent claims

A vacuum solvent reclamation system for removing heat stable salts, degradation products, and other contaminants from carbon dioxide (CO2) capture solvents, the vacuum solvent reclamation system comprising:

a feed product exchanger configured to increase the temperature of the CO2 capture solvents;
a reboiler that increases the temperature of the CO2 capture solvents emitted from the feed product exchanger such that the heat stable salts, the degradation products, and the other contaminants accumulate in the reboiler, wherein the feed product exchanger and the reboiler are in fluid communication to permit batch or semi-batch removal of the heat stable salts, the degradation products, and the other contaminants from the CO2 capture solvents;
and
a condenser that decreases the temperature of cleaned carbon dioxide (CO2) capture solvents emitted from the feed product exchanger.
