Absorbent, CO<sub>2 </sub>or H<sub>2</sub>S reducing apparatus, and CO<sub>2 </sub>or H<sub>2</sub>S reducing method using absorbent |
摘要 |
An absorbent according to the present invention absorbs CO2 or H2S contained in flue gas emitted from a power generating plant such as a thermal plant, and contains three or more amine compounds selected from linear or cyclic amine compounds having a primary amino group, and linear or cyclic amine compounds having a secondary amino group. By way of a synergetic effect of the mixture of these compounds, the absorption speed of CO2 or H2S absorption is improved. A small amount of CO2 contained in a large amount of boiler flue gas can be absorbed efficiently. |

1. An absorbent that absorbs CO2 or H2S contained in gas, the absorbent comprising:
a main component which is 2-ethylaminoethanol (EAE); minor components selected from any one of the following combinations: 1-(2-aminoethyl)piperazine (AEPRZ) and any one of piperazine (P), methylpiperazine (MP), 2-amino-2-methylpropanol (AMP) and piperidinol (PDN); piperazine (P) and piperidinol (PDN); methylpiperazine (MP) and piperidinol (PDN); and 2-amino-2-methylpropanol (AMP) and piperidinol (PDN); and water; wherein the main component accounts for 30 to 55 weight percent, the minor components account for 20 to 1 weight percent, and the water accounts for the remaining weight percent. |
