A distillation column (Fig. 1) 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%). <br/>Calculate, <br/>(i) The mass flow rate of distillate and bottom product per hour. <br/>(ii) Themassflowrateofrefluxperhour. <br/>(iii) The mass flow rate of liquid entering the reboiler and the vapour leaving the <br/>reboiler per hour. <br/>(iv) The mass flow rate of steam and cooling water per hour. <br/> <br/>There is a word limit of between 2000-2500 words for each assignment.
