Abstract: A fossil fuel fired power plant exhaust gas clean-up and recovery system is provided to remove detrimental exhaust gases from the power plant exhaust and to produce and reclaim various commercial byproducts. A process includes mixing one liquid solution with a solubilizer in a mixing tank containing water to create a chemical reaction therein to produce an ionic solid compound and an alkaline liquid solution. Simultaneously directing the flue gases and the alkaline liquid solution into the wet scrubber to create a chemical reaction therein. The chemical reaction removes various detrimental exhaust gases from the flue gases and captures CO2 gases therefrom, which are chemically transferred into a newly formed sodium bicarbonate solution. The sodium bicarbonate solution exiting the wet scrubber is stored for resale or reuse in the subject process. The process uses various pathways to distribute the sodium bicarbonate for producing other byproducts.

Abstract: A carbon processing system comprises an air mover and a multi-stage reactor. The multi-stage reactor processes ambient air and generates carbon dioxide and generates exhausted gas released to ambient air. In operation, air contacts the base solution via the air mover. The air reacts with the base solution thereby generating a base solution having carbon dioxide and generating exhaust (absorption reaction). Next, the exhaust is released from the reactor. Next, heat is applied to the base solution having carbon dioxide thereby generating carbon dioxide and generating a base solution without carbon dioxide (desorption reaction). The base solution without carbon dioxide generated after applying heat is reusable in processing new air. The absorption reaction and desorption reaction are reversible reactions resulting in regeneration of the base solution into its form prior to contact with the air yielding high scalability and less processing volume as required by many conventional carbon processing techniques.
