摘要
根据现有实验条件,设计、安装了一套静态法高压汽液平衡的测定装置,并通过测定CO_2的饱和蒸汽压检验了该装置的可靠性.针对本实验装置的特点,探索了一套简便、实用的高压相平衡实验的操作步骤,测定了N_2-CO_2体系的校正因子和在20.00℃,23.00℃,25.30℃,26.90℃,28.90℃5个温度下,压力为6~8MPa的汽液相平衡数据.用M-PR方程对实验数据进行处理,结果满意,且通过了热力学一致性检验.
Under available condition,a static high pressure vapour liquid equilibrium (VLE)
appratus was designed and built. Its liability was tested by measuring saturated vapour pres
sure of CO2. A suit of handy and available experiment procedure of high pressure phase equi
librium measurement has been determined. Furthermore,the corrected factor of N2 -CO2 sys
tem in gas chromatograph analysis and a series of VLE data for N2 - CO2 system at five tem
peratures (20. 00℃,23. 00℃,25. 30℃, 26. 90℃,28. 90℃). with the pressure range from 6
MPa to 8 MPa were measured. The results calculated by M - PR equation are satisfactory and
pass through the thermodynamic consistent test.
