摘要
选用二甲基亚砜作为一种新的脱硫吸收剂 ,用静态法在常压吸收装置中 ,实验测定了低浓度SO2 在二甲基亚砜中的溶解度。实验温度 2 93.15— 313.15K ,SO2 分压 0 .15— 3kPa ,根据测得的气液平衡数据 ,建立了溶解度模型。通过单纯形寻优法求得NRTL二元交互作用参数 。
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.
