Claim 3:
4. The method according to claim 3, wherein the first stream of the decarburizing solution and the second stream of the decarburizing solution are the lean liquid from the bottom of the regeneration tower; the first stream of the decarburizing solution directly countercurrent contacts with the gas stream III to obtain the first stream of the rich liquid; the second stream of the decarburizing solution first exchanges heat with a stream of the rich liquid having a lower temperature, then exchanges heat with a circulation washing water, and finally countercurrent contacts with the gas stream IIIa to obtain the second stream of the rich liquid; and the first stream of the rich liquid and the second stream of the rich liquid return to the regeneration tower for regeneration.
