Wilson方程关联和Virial方程修正常压下乙醇-水的汽液平衡
Correlation and modification on vapor-liquid equilibrium of water-ethanol system with Wilson equation and Virial equation at normal pressure
摘要
Abstract
In order to have a better understanding of the true nature of vapor-liquid equilibrium (VLE) of water-ethanol system and improve the prediction accuracy of VLE relationships of other alcohol-water systems, the densities of ethanol at different temperatures were determined by density bottle method, which combining with the azeotropic composition data of the ethanol-water system at atmospheric pressure were used to correlate and correct the VLE data by using Wilson Equation and Virial coefficient. The relation of vapor-liquid equilibrium modified was closer to the literature data, from which the maximum relative error of the vapor phase composition to the literature values was 2.690%, and the standard deviation was 0.1461.关键词
