VLE and VLLE for ternary mixtures of hydrogen-water-hexadecane, hydrogen-water-benzene, hydrogen-benzene-hexadecane and the quaternary hydrogen-water-benzene-hexadecane system were experimentally determined at temperatures of 200 to 350°C and pressures up to 300 bar. The applied experimental procedure is based on the analytical method. A 1000-cm3 autoclave with an electromagnetically driven stirrer was used for equilibration. Samples could be taken at three different heights. Experimental results show that at lower temperatures three-phase equilibria prevail, while at higher temperatures two-phase VLE are more common. For the representation of the experimental data a special graphic program for a Hewlett-Packard microcomputer was developed. With a modified Redlich-Kwong equation of state some of the measured systems could be correlated successfully. © 1986.
