An experimental apparatus was developed for me aeuring the relations of vapor-liquid equilibria at high pressure by vapor circulating method. A special feature of the appa-ratus was the. The liquid surface in the equilibrium cell was detected with floating magnetic needle coupled. Vapor-liquid equilibrium data for hydrogen-carbondioxide system at 0°C were obtained by the apparatus up to 370atm. and the data of nitrogencarbondioxide system at 0°C were also obtained. Eeima-tion of the vapor-liquid equilibrium was carried out by the BWR zed constants. The results of calculation were not so good. But it was ascertained that the method is useful when the BWR constants are not evailable.
