200 kmole/hr at 4 bar and 30 C containing 40% styrene, 25% methanol and 35% toluene (molar %) is sent to a pre-heater using heat recovered from the overhead product prior to being sent to a 21-stage distillation column with a total condenser and kettle reboiler as shown in the PFD below. The pre-heater is designed to heat the process liquid prior to the feed entering above stage 10. The distillate product is cooled to 35 C. The stage 1 pressure is 2.5 bar with a 0.2 bar drop across the condenser on the process side. The bottoms pressure is 3.5 bar. Use a mass balance to set either the distillate or the bottoms flow rate and then use a design specification such that styrene with a purity of 99.95% is to be recovered in the bottoms by varying the reflux ratio. Use the NRTL method with UNIFAC for estimation Use RADFRAC to model the column Use two heater blocks and a heat stream to model the pre-heater/product cooler heat exchange Ignore pressure drops in the heater blocks What is the temperature of the feed entering the column in oC?    __     _________________ What is the duty of the product cooler/pre-heater in GJ/hr?  _____         ______________ What is the reflux ratio required to achieve the desired product purity?   ________________ What is the energy consumption in the reboiler in GJ/hr for 99.95% pure styrene?_____           ___________________ What is the diameter in meter for this column if sieve trays with 4 tray passes and default tray spacing are used? ___       _______________
