Vapor-Liquid Equilibrium Measurements and Correlation of the Methylal-Methanol Binary System
摘要
Abstract
Vapor liquid equilibrium of the methylal-methanol binary system under pressure of 99.9kPa was investigated with an improved ROSE still. All VLE experimental data were thermodynamically tested with the Herrington method. Binary interaction parameters of Wilson and NRTL equations were presented, and the relationship between the interaction parameters and temperature was revealed. The results show that the two models have numerical results consistent with the experimental results of liquid phase composition and bubble point temperature. The relative average deviation of the mole fraction of vapor phase composition for Wilson equation is 7.99%, and that of the bubble point temperature is 0.12 K. These two values are 7.66% and 0.22 K for the NRTL model.关键词
