A distillation column separates 4500 kg/hr of a 40% benzene - 60% chlorobenzene liquid mixture at 20oC. The liquid product from the top is 99.5% benzene while the bottoms (stream leaving the reboiler) contains 1% benzene. The condenser uses water that enterso at 15oC and leaves at 60oC, whilst the reboiler is heated by saturated steam at 120 C. The reflux ratio is 6:1. Assume that both the condenser and reboiler operate at 1 atm pressure, that the temperature calculated for the condenser is 80oC and for the reboiler 130oC. The calculated fraction of benzene in the vapour from the reboiler is 3.9 wt% (5.5 mole%).

Calculate,

(i) The mass flow rate of distillate and bottom product per hour.

(ii) Themass flowrate of reflux pe rhour.

(iii) The mass flow rate of liquid entering the reboiler and the vapour leaving the reboiler per hour.

(iv) The mass flow rate of steam and cooling water per hour.

There is a word limit of between 2000-2500 words for each assignment.
