EQUILIBRIUM PHASE COMPOSITIONS, PHASE DENSITIES, AND INTERFACIAL-TENSIONS FOR CO2 + HYDROCARBON SYSTEMS .6. CO2 + NORMAL-BUTANE + NORMAL-DECANE

Experimhental vapor-liquld equilibrium phase compositions, phase densities, and interfacial tensions are presented tor the ternary system CO2+ n-butane + n-decane at 160 °F. Measurements were made on a mixture of constant overall molar composition of 90.2% CO2, 5.9% n-C4, 3.9% n-C10at pressures from 1310 psia to a near-critical dew point state at 1675 psia. Additional data were obtained at a constant pressure of 1600 psia. The measured phase compositions are in agreement with the data of Metcalfe and Yarborough. The phase densities and interfacial tensions represent data not previously available in the literature. © 1990, American Chemical Society. All rights reserved.
