摘要
在汽相循环的加压汽液平衡装置中,测定了263.15-288.15K,351.6-5044KPa范围内CO_2-CHClF_2、N_2-CHClF_2二元体系及N_2-CO_2CHClF_2三元体系的汽液平衡数据.用PR、SRK、PT和MSRK状态方程关联二元体系数据并推算三元体系的汽液平衡,均获得满意的结果.
Vapor-liquid equilibrium data for the CO_2-CHClF_2N_2-CHClF_2 and N_2-CO_2- CHClF_2 system at temperature between 263.15 and 288.15K, and pressure between 351.6 and 5044KPa were determined with a vapor phase circulation apparatus.The equilibrium data have been correlated for binary systems and predicted for ternary systems with PR SRK PT and MSRK equations of state. The satisfactory result has been obtained.
