A separation stream off the main reactor effluentcontains almost exclusively ethyl benzene,benzene, and toluene at 1 bar and 100°C. You determinethat the stream flow rate is made up of34 kg/s of benzene, 10 kg/s of toluene, and 57.75kg/s of the other component. You send this mixtureinto a flash distillation unit operating at 0.6bar and 100°C.A. Estimate if this mixture flashes.B. If the mixture flashes, determine the compositionand amount of the equilibrium liquid andvapor.C. You send the liquid exiting the flash distillationunit into another flash distillation unitoperating at 1.5 bar and 140°C. Determineif this mixture flashes. If so, determine thecomposition and amounts of the equilibriumphases.D. What percentage of the original benzene thatleft the reactor is now a vapor (you have to considerboth flash units).

Question
| A separation stream off the main reactor effluent contains almost exclusively ethyl benzene, benzene, and toluene at 1 bar and 100°C. You determine that the stream flow rate is made up of 34 kg/s of benzene, 10 kg/s of toluene, and 57.75 kg/s of the other component. You send this mixture into a flash distillation unit operating at 0.6 bar and 100°C. A. Estimate if this mixture flashes. B. If the mixture flashes, determine the composition and amount of the equilibrium liquid and vapor. C. You send the liquid exiting the flash distillation unit into another flash distillation unit operating at 1.5 bar and 140°C. Determine if this mixture flashes. If so, determine the composition and amounts of the equilibrium phases. D. What percentage of the original benzene that left the reactor is now a vapor (you have to consider both flash units). |
