磁场对正丁醇-水物系汽液平衡的影响

摘要为探讨磁场对二元共沸物系汽液平衡的影响,在不同磁感应强度的磁场中,研究了正丁醇-水物系的汽液平衡。结果表明,外加磁场对正丁醇-水物系的汽液平衡有一定的影响,总体上呈正效应,即外加磁场有利于该物系的精馏过程。采用NRTL模型对正丁醇-水物系的汽液平衡数据进行了拟合,得到了不同磁感应强度下的NRTL模型参数,并进行了热力学一致性检验,验证了试验数据的可靠性。

Abstract： In order to investigate the influence of magnetic field on the vapor-liquid equilibrium of binary azeotrope,the vapor-liquid equilibrium of n-butanol-water system was studied under magnetic field with different magnetic induction intensity.The results show that the magnetic field has influence on the vapor-liquid equilibrium of n-butanol-water system and the influence is positive effect,the magnetic field is helpful for the rectification process of n-butanol-water system.The vapor-liquid equilibrium data of n-butanol-water system was correlated by NRTL model and the parameter of NRTL model under different magnetic induction intensity was obtained.Thermodynamic consistency test was made and showed the experimental data was reliable.
