| Abstract: | Selecting dimethyl sulfoxide (DMSO) as an organic absorbent, a solubility apparatus based on static method was set up, and SO 2 solubility in DMSO was determined from 293.15 to 313.15K and partial pressure of SO 2 from 0.15 to 3kPa. Gas liquid equilibrium model was proposed.In this model, interaction parameters of NRTL equation were optimized. The solubilities calculated by the model showed good agreement with experimental data. |
