| titleOfInvention | Solvent for removing CO2 and sulfides in acidic airflow, and application thereof |
| abstract | The invention discloses a solvent for removing CO2 and sulfides in an acidic airflow, and application thereof, and aims to provide a solvent capable of removing CO2 and the sulfides in high removal rate. The solvent comprises the following components in percentage by weight: 20-60% of an amine compound, 1-10% of an activating agent, and the balance of water, wherein the activating agent comprises tetramethylene sulfone and diethylene glycol, and the amine compound is N-methyldiethanolamine. The solvent provided by the invention can remove CO2 and the sulfides from acidic gas, adopts the amine compound as a main absorbent, is supplemented with the activating agent consisting of tetramethylene sulfone and diethylene glycol, and can improve the removal rate of the CO2 and the sulfides through mutual synergy. Compared with a conventional desulfurization method, the solvent can effectively remove acidic substances such as H2S, CO2, COS and mercaptans, so that the treatment processes are reduced, and a higher economic value is provided. Meanwhile, the solvent further has the advantages of being renewable, low in cost and good in effect, can realize cyclic utilization, and has an important significance of reducing treatment cost of the acidic gas. |
