摘要:
为了解决1,2-丙二醇与乙二醇的分离问题,采用汽相单循环法测定了绝压6.67 kPa条件下1,2-丙二醇-乙二醇二元体系的汽液平衡数据;并用Herrington面积检验法对实验数据进行热力学一致性检验,结果表明实验数据符合热力学一致性.分别用Wilson、NRTL和UNIQUAC模型对汽液平衡数据进行关联,得到了各个模型的二元交互作用参数,并对汽液平衡数据的模型计算值与实验值进行比较,发现二者偏差较小,可满足工程上分离设计的需要.
Abstract:
In orderto separate 1，2一propyleneglycol and ethylene glycol，the methodof only vapor phase cir— culation wasused to measure vapor—liquid equilibrium values at 6．67 kPa．And the experimental data of the binary system measured in this work passed the thermodynamic consistency test according to Herington area method．The experimental data of the binary system were correlated by Wilson，NRTLandUNIQUAC activity coefficientmodels．And all the models showed rather smaller deviation from the experimental results，indica— ting that the experiment data are suitable for the further industry process design．
