Find the bubble T of a mixture whose molar composition is 10% propane, 40% n-butane, and 50% n-pentane that is fed as a saturated liquid to a column at 758 kPa. a) Determine the new value of the bubble point temperature when including as a fourth component in the mixture above, the n-hexane with 15% mol and modify the fraction of n-pentane to 35% mol. The solution for the bubble T is T=? K. b) Determine the new composition of the vapor in equilibrium with this saturated liquid.
