A new experimental apparatus for performing simultaneous determination of high-pressure vapor-liquid equilibria (VLE) and saturated densities was developed in this work. The experimental methodology was verified by measuring these properties for the carbon dioxide + 1-propanol and carbon dioxide + 2-propanol systems from 313 to 363 K. The apparatus is based on the static-analytic method for VLE determinations and was slightly modified by coupling a vibrating U-tube densitometer to obtain saturated densities for both vapor and liquid phases. VLE measurements agreed with previous literature data and were correlated with the Peng-Robinson equation of state coupled to the Wong-Sandler mixing rules. Saturation densities at temperatures above 313 K have not been published up to now. (c) 2010 Elsevier B.V. All rights reserved.
