Calculation of bubble and dew points The dew point of a mixture is the point (temperature and pressure) at which a vapor will start condensing. Similarly, the bubble point is the point at which a liquid starts boiling. In other words, the vapor fraction at the dew point is 1, while it is 0 at the bubble point.

App Preview: Bubble point pressure.Calculation of the Bubble Point Pressure for a mixture using the Peng Robinson Equation of State and simple mixing rules.2000 John KitchinAll Rights ReservedUniversity of DelawareDepartment of Chemical Engineering restart:This worksheet calculates the bubble point pressure of a mixture using the complete generalized Peng-Robinson equation of state shown below. The parameters are calculated using the Van der Waal mixing rules from the pure component properties.The bubble point pressure of a mixture is defined as the pressure where the first bubble of vapor is formed at a given temperature. The strategy to calculate this pressure is to assume that the very first bubble will not change the composition of the liquid, and will not have the same composition as the liquid (otherwise it would be the liquid phase).
We will make a guess for what the pressure and vapor composition should be, and then iterate on both of them until all of the species fugacities (calculated using the Peng Robinson EOS for a mixture) are equal in each phase. The end result will be the bubble point pressure and vapor composition in equilibrium with the liquid mixture.The algorithm is based on the one presented in Chemical and Engineering Thermodynamics, 3rd Ed., S.I. Sandler on page523. All of the data used is obtained from tables in this book.
