The use of dual effect solvents (near critical extractant and high-pressure water entrainer), for the recovery and dehydration of alcohols from dilute aqueous solutions, has been proposed by Brignole et al. (1987). The present work is part of an experimental program undertaken to confirm the applicability of light hydrocarbons for this separation problem. Vapor-liquid equilibria have been measured for propane + 2-butanol, propylene + 2-butanol, and propane + 2-butanol + 2-propanol in the temperature range of (328.1 to 368.1) K and at pressures up to 44.45 bar. The data were correlated using a group contribution equation of state for associating mixtures.
