APPLICATION OF A MODIFIED OTHMER VAPOR-LIQUID EQUILIBRIUM ON EXAMPLE THE OF THE BINARY ACETONE-ISOPROPANOL SYSTEM AND EVALUATION OF THE ADEQUACY OF VAPOR-LIQUID EQUILIBRIUM MODELS FOR CALCULATION OF PHASE COMPOSITION

Abstract

A modification of the Othmer device with a reduced volume of vapor space was proposed. Data on the vapor-liquid equilibrium were obtained on the example of the binary acetone-isopropanol system, and the thermodynamic consistency was checked. The main models for calculating vapor-liquid equilibrium are considered
