Abstract
The invention discloses a method for removing CO2 from a gas. The method is characterized in that one of triethylene tetramine or tetraethylenepentamine reacts with H3BO3 with same mole to generate an aqueous solution of ammonium salt to serve as an absorbent; the absorbent is in contact with a CO2-containing gas to absorb and remove the CO2, wherein the mass percentage of the absorbent, namely the aqueous solution of the ammonium salt, is 10 to 20 percent; the volume percentage concentration of the CO2 in the absorbed gas is 0.1 to 85 percent; the absorption temperature is 0 to 50 DEG C; after the CO2 is absorbed, the absorbent, namely the aqueous solution of the ammonium salt, can be reused after being heated to desorb the CO2 at normal pressure; the temperature for desorbing the CO2 is 70 to 103 DEG C, and the time is 20 to 120 minutes. Compared with the prior art, firstly, the carbon removal speed of the absorbent is high, the CO2 load is large, and the recycling performance is high; secondly, the CO2 is easy to desorb after being absorbed; thirdly, the absorbent is easily dissolved in water and does not have saturation vapour pressure, and the problem of scaling to block equipment is avoided.
