Anlage und Verfahren zur Kohlendioxid-Sorption für Treibstoff- und Gasemissionen

摘要

A system and method for controlling carbon dioxide (CO2) emissions emanating from a gas source includes a CO2 sorbent bed 20, 22 containing a regenerable sorbent. Exhaust gases flow through the CO2 sorbent bed before being released into the atmosphere. The CO2 sorbent bed 20, 22 traps CO2 contained within the exhaust gas to control the amount of CO2 finally exhausted to the atmosphere. At least two CO2 sorbent beds 20, 22 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.
