| titleOfInvention | A kind of solvent for recovering SO2 from flue gas |
| abstract | The invention discloses a solvent for recovering SO 2 from industrial waste gas, comprising a main absorbent, a co-absorbent and an additive; the main absorbent is composed of 1-butyl-3-methylimidazolium thiocyanate ionic liquid and N,N-2-Hydroxyethylpiperazine is composed, the mass ratio of the two substances is (1-2): (0.5-3), and the mass ratio of the main absorbent to the total absorbent is 95-99%; the described The absorbent is one or both of sulfuric acid and sulfurous acid mixed, and the mass ratio of the absorbent to the total absorbent is 0.5-5%; the additives include 2-amino-2-methyl-1-propanol, Triethylene glycol monomethyl ether and hydroquinone, the mass ratio of the three substances is (1‑3):(1‑2):(0.5‑1), and the mass ratio of the additive to the total absorbent is 0.05‑0.5 %. The invention has high absorption efficiency and no secondary pollution. |
