Continuously Regenerable Scrubber

Last updated:

Abstract:

Regeneration of a fluid medium can be accomplished using a continuously regenerable scrubber, which, in its various embodiments, combines valve functions and sorbent material, such as amine beds, into one component, dramatically reducing size and mass of scrubber. Sorbent material beds rotate continuously past breathing gas vent loop ports for scrubbing CO.sub.2/H.sub.2O and then past vacuum ports for regenerating the sorbent material. Typically, a first fluid output is connected to a lower header fluid output and a second, sweeping fluid source connected to a lower header fluid input. A motor spins the substantially circular bed assembly at a predetermined speed which allows adsorption or absorption as well as desorption of materials flowing through the sorbent material.
