A liquid mixture of the composition given in Problem 10.3-1 is to be flashed at P = 20 bar and a collection of temperatures between the bubble point temperature and the dew point temperature. Determine the compositions of the coexisting vapor and liquid, and the vapor-liquid equilibrium split for several temperatures in this range.

Problem 10.3-1

The following mixture of hydrocarbons occurs in petroleum processing. 

Estimate the bubble point temperature and the composition of the coexisting vapor for this mixture at all pressures above 1 bar.
