1. , a kind of continuation method that from carbon dioxide enriched air-flow, reclaims carbonic acid gas, this air-flow is contacted with a kind of alkanolamine aqueous solution in the uptake zone, form the cat head effluent stream of poor carbonic acid gas and carbon dioxide enriched effluent liquid stream, carbon dioxide enriched effluent liquid stream is heated in the breeding blanket, form the effluent liquid stream of carbon dioxide enriched cat head effluent stream and poor carbonic acid gas, above-mentioned poor carbonic acid gas effluent liquid stream contains the regenerated alkanolamine aqueous solution, this regenerated alkanolamine aqueous solution is sent back in the uptake zone again, and the innovative approach of this method comprises:

  • Make the regenerated alkanolamine aqueous solution be cooled to be enough to make this solution in most uptake zone, to remain on and be not higher than about 35 ℃

    temperature, the most about 20% (weight) of concentration that the above-mentioned regenerated alkanolamine aqueous solution contains alkanolamine, and will import the uptake zone through the overcooled regeneration alkanolamine aqueous solution, so that it contacts above-mentioned carbon dioxide enriched air-flow and from wherein removing carbonic acid gas.
