Carbon dioxide scrubber for fuel and gas emissions
First Claim
1. A system of removing carbon dioxide (CO2) from a gas produced in energy extracting systems comprising;
- a CO2 sorbent bed including a CO2 sorbent, a conduit for communicating a source of gas containing CO2 with said sorbent bed, a conduit for communicating said sorbent bed with an outlet, a regeneration device for evolving CO2 from said CO2 sorbent bed, and at least one valve disposed to control a flow of said gas into and out of said sorbent bed.

Abstract
A system and method for controlling carbon dioxide (CO2) emissions emanating from a gas source includes a CO2 sorbent bed containing a regenerable sorbent. Exhaust gases flow through the CO2 sorbent bed before being released into the atmosphere. The CO2 sorbent bed traps CO2 contained within the exhaust gas to control the amount of CO2 finally exhausted to the atmosphere. At least two CO2 sorbent beds are used such that while one is absorbing CO2 from the gas stream another is being regenerated. The CO2 sorbent bed is regenerated to release the trapped CO2 for disposal or use in other processes. The CO2 sorbent beds are cycled between absorbing CO2 and regenerating to optimize absorption of CO2.

17. A method for removing carbon dioxide (CO2) from a gas containing CO2 extracted from an energy producing system, said method including the steps of:
-
a. communicating a CO2 sorbent bed with the gas containing CO2. b. absorbing CO2 contained within the gas with the sorbent bed;
c. concentrating said CO2 within said sorbent bed, and d. expelling said CO2 from said sorbent bed upon reaching a predetermined concentration level of CO2.
