摘要
分析了高压下甲烷在烷烃、环烷烃、芳香烃和乙烯共计 2 3种烃类溶剂中的溶解度数据 ,对在同一温度不同压力下的数据进行了关联得出相应的亨利系数 ,分析得知甲烷在所分析数据的压力范围内符合亨利定律。拟合得到了亨利常数与温度关联式的系数 ,同时提出了以临界体积为参数的甲烷在烃类溶剂中的亨利系数的估算方法。
The solubility data of methane in hydrocarbons,ranging from alkanes,aromatichydrocarbons,cycloalkanes and ethenes,were researched and Henry constants were gotten by correlating the data of different pressures in the same temperature.It was proved that Henry law is applicable at the researched pressures. The effect of solvent carbon atoms and construction of hydrocarbons on methane's Henry constant has been studied in detail.The temperature coefficients of Henry constant were correlated.At the same time,a method was advanced to estimate methane Henry constants in hydrocarbons using critical volume.The above data and calculation methods are valuable for the application of liquid natural gas.
