Process and equipment for removing CO2 in flue gas by utilizing amine solid adsorbent

The invention belongs to the technical field of separation of CO2 in flue gas discharged during s combustion process, and in particular relates to a process and equipment for removing CO2 in flue gas by utilizing an amine solid adsorbent. In the process, the CO2 gas in the flue gas is fully contacted with the amine solid adsorbent so that CO2 gas molecules are rapidly diffused into pores of the solid adsorbent to react with amine liquids in the pores and then the CO2 is rapidly adsorbed by the adsorbent, and meanwhile the amine solid adsorbent adsorbed with the CO2 is regenerated by utilizing one or more regeneration methods such as thermal regeneration, vacuum regeneration, steam regeneration, amine steam regeneration and gas introduction regeneration. The adopted main equipment consists of a CO2 absorption reactor using the amine solid adsorbent, a regeneration reactor, a gas-solid separator, a gas-liquid separator and the like. The process and equipment provided by the invention have the advantages of simple and compact overall design, low investment and operating cost, stable and reliable operating performance and capability of efficiently separating the CO2 in the flue gas with low cost.
