Consider the distillation of a hydrocarbon stream composed of 35 mol% isopentane, 35 mol% n-hexane, and 30 mol% n-heptane supplied as a two-phase mixture that is 40% vapor at 100 kmol/h. The vapor and liquid products coming out from the flash distillation are in equilibrium each other. The distillation operated at 1520 mmHg pressure and 111°C. Required:
Determine the vapor and liquids flow rates and compositions of the outlet.
