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.
