Consider a flash drum operating at 69oC that is fed a mixture of n-pentane, n-hexane and nheptane at compositions of 0.55, 0.25 and 0.20, respectively. The vapor pressures for these compounds are 2.755, 1.021, and 0.39 bar, respectively at this temperature. Determine the dew point pressure of this mixture and the liquid composition.
