Abstract: The present disclosure relates to a method for stripping acid gases, exemplified by carbon dioxide, from absorption media and/Alcohol selected from those having a boiling point lower than the boiling point of the absorption medium and/or adsorption medium.

Abstract: The present invention relates to a method for removing carbon dioxide (CO2) from a gas stream. Particularly, the present invention relates to a method for removing CO2 from a gas stream by a liquid absorbent having an amino alcohol derived from 4-amino-2-butanol. In comparison to conventional amines, the amino alcohols of the present invention have been found to provide a higher CO2 absorption capacity and a higher cyclic capacity for CO2 removal.

Abstract: Apparatus comprising an absorber device provided with a plurality of sequentially adjacent sections for flowing a gas stream therethrough. A solvent reactable with components of the gas stream is ingressed into and egressed from each section of the absorber device by a conduit infrastructure. The conduit infrastructure has a plurality of heat exchange and cooling equipment, and communicates with solvent recovery and regeneration equipment. A process wherein a liquid solvent selected for reacting with gaseous components, is counter-flowed against the gas stream. The liquid solvent temperature is controllably manipulated between each section of the absorber device to provide: (a) thermodynamic-driven mass transfer at the front end of the absorber device, and (b) kinetic-driven mass transfer at the back end of the absorber device. Heat generated during recovery of gaseous components from the liquid solvent is recovered for use in regenerating the solvent system.

A conduit infrastructure comprising a section configured to ingress, communicate with and egress from each section of the absorber device, and a recovery and regeneration section, is configured with a plurality of heat exchange and cooling equipment. A process wherein a liquid solvent provided with at least one chemical compound selected for reacting with the selected gaseous component, is counter-flowed against and commingled with the gas stream. The liquid solvent temperature is controllably manipulated between each section of the column to provide: (a) thermodynamic-driven mass transfer at the front end of the absorber device, and (b) kinetic-driven mass transfer at the back end of the absorber device. The heat generated during the recovery of the gaseous component from the absorption liquid solvent system is recovered for use in regenerating solvent system.
