Patent ID: 8784532

Claim:
A method, comprising: providing hollow-fiber contactors in a desorption unit where the hollow-fiber contactors are formed by spinning a composition doped with a conducting agent; passing a sorbent loaded with at least one of carbon dioxide and hydrogen sulfide along the hollow-fiber contactors of the desorption unit; and heating the sorbent by at least one of applying a voltage across the hollow-fiber contactors heated by electrical resistance and directing at least one of microwave and radiofrequency energy toward the hollow-fiber contactors which are heated upon absorbing the energy, wherein the heating of the sorbent through thermal contact with the hollow-fiber contactors which are heated results in absorbed gases including at least one of the carbon dioxide and the hydrogen sulfide being released from the sorbent and transferred across walls of the hollow-fiber contactors through pores of the hollow-fiber contactors to regenerate the sorbent.
