A New Apparatus for Measuring Vapor-Liquid Equilibria of Gas-Solvent Systems at Constant Pressure

Abstract

A new apparatus is proposed for measuring isobaric vapor-liquid equilibria of gas-solvent systems. It is based on the determination of vapor-liquid equilibria from boiling point measurements. The vapor composition in equilibrium with liquid solutions is calculated by using the method of Mixon et al. The experimental results are obtained for two binary systems, ammonia-water and propylene-acetone, at 760mmHg. In the ammonia-water system, the experimental data are in good agreement with those found in the literature.
