摘要
介绍了气液平衡数据测定装置可靠性的一种检验方法。以气相单循环气液平衡仪为实验装置,分别对乙醇-水体系及水-醋酸体系的常压气液平衡(VLE)数据进行了测定,用气相色谱仪分析气、液相组成并与文献值比较,同时用Herington面积法对所测VLE数据进行热力学一致性的检验,从而考察了本实验装置测定气液平衡数据的稳定性及可靠性。
A reliability test for the vapor-liquid equilibrium （VLE） apparatus was presented. The atmospheric VLE data of both the ethanol-water system and the acetic acid-water system were measured respectively with a VLE apparatus and gas chromatograph. Comparing the measured VLE data with those of the literatures and checking the thermodynamic consistency by Herington method, the reliability of the vapor-liquid equilibrium apparatus was then successfully tested.
