Measurement and Correlation of Phase Equilibria for Water + Decane + 2-Propanol, Water + Hexane + 2-Propanol, and Water + Decane + 2-Butanol Ternary Systems at 573 and 593 K and 15.0 and 20.0 MPa

Abstract

The phase equilibria for the water + decane + 2-propanol system at (573 and 593) K and (15.0 and 20.0) MPa, the water + hexane + 2-propanol system at 573 K and 20.0 MPa, and the water + decane + 2-butanol system at 573 K and 20.0 MPa were measured with a flow type apparatus. The experimental results were correlated by a modified SRK equation of state. An exponent type mixing rule and a conventional mixing rule were applied for the energy and size parameters of the equation of state, respectively. The average deviation between the mole fractions of experiment and correlation is 0.006.
