1. A continuous fraction distillation column 42% benzene with a flow rate of 30,000kg/h and 58% toluene, 97% benzene in the top product and 98% in the bottom product by weight will be designed for toluene containment limitation. Recovery (reflux) rate, 1 mole of product 2.8 will be used for Benzene and toluene are combined with a relative use-value of 1.8. ideal system is formed. Molal latent heat values for benzene and toluene are 7360 , respectively. and 7960cal/gmol. Collection weights for benzene and toluene are 78 and 92, respectively. g/mol. Supply has gate point at 95C at 1 atm pressure 16:43 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) 20lbf/ 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? 16:44
