Mutual solubility of 1-butanol and carbon dioxide, ethene, ethane, or propane at a reduced supercritical solvent temperature of 1.03

High-pressure vapor-liquid equilibrium measurement for the binary mixtures of carbon dioxide+n-butanol

“…Table 3 lists the interaction parameters of binary mixtures for each isotherm and the average absolute deviations in pressure (AAD-P (%)) and average absolute deviations in vapor phase compositions (AAD-y 1 ) between measured and calculated values for the mixture of CO 2 (1)+ n-butanol (2). The values of binary parameters (κ 12 ) determined at (313.…”

“…The vapor-liquid equilibrium data for the binary systems of CO 2 (1)+n-butanol (2) were measured at four equally spaced temperatures between 313.15 and 343.15 K using a circulation-type equilibrium apparatus. The experimental VLE data were correlated with the Peng-Robinson equations of state combined with the WongSandler mixing rules.…”

“…As a result, attention has been placed on the thermodynamic understanding of fluid systems [1,2]. During the last two decades, efforts have been focused on the understanding of phase equilibrium behaviors of fluids near the critical region of mixtures as well as pure fluids due to the emerging technology of supercritical fluids.…”

Vapor-liquid equilibria of carbon dioxide+n-propanol at elevated pressure

“…The vapor-liquid equilibrium data for the binary systems of CO 2 (1)+n-propanol (2) were measured at four equally spaced temperatures between 313.15 and 343.15 K by using a circulation-type equilibrium apparatus. The experimental VLE data were correlated with the Peng-Robinson equations of state combined with the WongSandler mixing rules.…”

“…As a result, attention has given to the thermodynamic understanding of fluid systems [1,2]. Also, during the last two decades, efforts have been focused on an understanding of the phase equilibrium behavior of fluids near the critical region of mixtures as well as pure fluids due to the emerging technology of supercritical fluids.…”
