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.

The drop-by-drop evaporation of a liquid or solution is controlled by monitoring the disappearance of each successive droplet and by actuating the deposition of the next droplet until the desired volume is deposited. In the case of a solution, non-volatile residue (NVR) is collected on a deposition surface plate as a relatively small mound. One of a variety of methods may be employed to measure the evaporative behavior of each droplet and to key the deposition procedure. The process is preferably carried out employing a clean deposition surface plate that is maintained at or below the boiling point of the particular liquid or solvent being deposited. The environment is preferably controlled so that inadvertent contamination is precluded from interfering, and thus the method permits the automatic, micro-processor controlled evaporation of liquids with the resultant deposition of non-volatile residues from solutions within relatively short periods of time. The deposited residue may then be quantified at levels down to and below about 1 ug/mL (1 mg/L) by one of several means for determining the amount of non-volatile residue remaining.

The present invention is directed to aqueous coating compositions, such as paints, containing a film-forming latex polymer and a reactive surfactant and/or a low VOC humectant. The reactive surfactant, a polyglycerol ester or ether of an unsaturated fatty acid, reduces or eliminates the need for traditional water-soluble additives that lower the water resistance of the dry coating. Additionally, the reactive surfactants of the invention are capable of oxidative cross-linking during the curing process, forming a dry film that is more durable and water-resistant than traditional latex paint composition. The low VOC humectant polyglycerol, isosorbide, or a derivative of isosorbide can replace at least in part traditional humectants such as propylene glycol which contribute to VOCs, while maintaining an effective open time for application of the aqueous coating compositions.
