C1. Determine the effect of pressure on the temperature, separation and diameter of a flash drum.
C2. Solve the Rachford-Rice equation for V/F for a binary system.
C3. Assume that vapor pressure can be calculated from the Antoine equation and that Raoult’s law can be used to calculate K values. For a binary flash system, solve for the drum pressure if drum temperature and V/F are given.
C4. Derive Eq. (2-24) and show that it is correct.
C5. Choosing to use V/F to develop the Rachford-Rice equation is conventional but arbitrary. We could also use L/F, the fraction remaining liquid, as the trial variable. Develop the Rachford-Rice equation as f(L/F).
C6. In flash distillation a liquid mixture is partially vaporized. We could also ...
