对多相Bunsen反应的速率控制步骤即SO₂溶于水和甲苯的过程进行模拟研究。选择Flash2作为单元操作模块，分别使用ELECNRTL模型和RK-SOAVE模型描述SO₂-水体系和SO₂-甲苯体系的物性，对高温高压条件下SO₂-水体系的亨利系数进行校正。最后利用灵敏度分析模拟计算了不同温度和压力下SO₂在水和甲苯中溶解度的变化规律。

H₂S chemical reaction cycle is an effective method to reutilize sulfur-containing pollutants for producing hydrogen and sulfuric acid.Bunsen reaction is the major bottleneck to realize H₂S chemical reaction cycle.Using iodine-toluene to conduct the multi-phase Bunsen reaction at ambient temperature can suppress side reactions,and avoid the deposition of iodine vapor and mitigate corrosion issues.This study aims to simulate the dissolution of SO₂ in water and toluene,which is the rate controlling step of the multi-phase Bunsen reaction.Flash 2 module is used as the unit operation module.ELECNRTL model and RK-SOAVE model are respectively used to describe the physical properties of the SO₂-water system and the SO₂-toluene system.Henry's coefficient of the SO₂-water system at high temperature and high pressure is modified.In addition,the variations of the solubility of SO₂ in water and toluene at different temperatures and pressures are investigated by using the sensitivity analysis.
