Some of the most important processes in the Chemical Process Industry are geared toward separating components from a mixture. One of the simplest ways to do this is to exploit thermodynamic differences in the phase behavior of the components.
One method of exploiting these differences is through flash distillation.
Flash distillation is the process by which a portion of a mixture is vaporized and then the vapor and liquid phases are separated.
If our mixture is simply binary, then the Gibbs Phase rule states that (2 + 2 - 2 = 2) two intensive variables must be specified before we can know everything about the thermodynamic state of the system.
