A continuous fraction distillation column 42% benzene with a flow rate of 30,000 kg/h and 58% toluene, 97% benzene in the upper product and 98%

A continuous fraction distillation column 42% benzene with a flow rate of 30,000 kg/h and 58% toluene, 97% benzene in the upper product and 98% in the lower product by weight. It will be designed to separate to contain toluene. Recovery (reflux) rate, 1 mole of product determined to be 2.8 for Benzene and toluene have a relative volatility of 1.8. constitutes an ideal system. Molal latent heat values for benzene and toluene are 7360, respectively. and 7960 cal/gmol. The molecular weights for benzene and toluene are 78 and 92, respectively. g/mol. The feed has a boiling point of 95C at 1 atm pressure. a) Calculate the amount of upper and lower product in mol/h. b) Specify the ideal number of stages and the stage where the feed is made for the following three different situations. Please specify. i) If the feed is liquid at boiling point ii) Feed liquid at 20C (specific heat 0.44 cal/gC), iii) A mixture of two-thirds liquid and one-third steam of the feed c) 20 lbf/in2 for heating If steam with a gauge pressure of (1.36 atm) is used, reduce heat losses. ignoring it and assuming the reflux is a saturated liquid, the above How much steam is required per hour for each of the three states? d) If the cooling water enters the condenser at 32C and leaves at 48C, how many cubic meters per hour? Need cooling water?
