A flash drum operating at \(300 \mathrm{kPa}\) is separating \(1000.0 \mathrm{kmol} / \mathrm{h}\) of a mixture that is \(40.0 \mathrm{~mol} \%\) isobutane, \(25.0 \% \mathrm{n}\)-pentane, and \(35.0 \% \mathrm{n}\)-hexane. We wish a \(90.0 \%\) recovery of \(n\)-hexane in the liquid. Find \(T_{\text {drum }}, x_{i}, y_{i}\), and V/F. Use DePriester charts or Eq. (2-28). \(90.0 \%\) recovery of \(n\)-hexane in the liquid. Find \(T_{\text {drum }}, x_{i}, y_{i}\), and V/F. Use DePriester charts or Eq. (2-28).
