Abstract

The solubility of hydrogen sulfide (H₂S) in piperazine (PZ) promoted N-methyldiethanolamine (MDEA) aqueous solution was investigated. The temperature ranged from 303.2K to 323.2k. The mass fraction of MDEA and PZ respectively ranged from 0.3 to 0.4 and 0 to 0.075. On the basis of experimental measurement, the effects of mass fraction and temperature on the solubility of H₂S in PZ-MDEA aqueous solution are illustrated.
