This application calculate the vapor-liquid equilibrium of a benzene-toluene mixture. Specifically, the application calculates the:
- temperature, given the composition of the liquid phase and pressure
- dew point and composition of the liquid phase given composition of the vapor phase and pressure
The application employs the empirical Antoine equation to calculate the vapor pressures of benzene and toluene. The parameters are sourced from the NIST Chemistry Webbook.
The techniques used here can be applied to many other mixtures - you just need to find the right data for the Antoine equation.
