It is distilled at 405.3 kpa in a 100 kmol/hr liquid fed distillation tower and the mole fraction of the components is given. 90 percent of the n-pentane is separated in the top product and 90 percent of the n-hexane is recovered at the bottom. All of the n-butane is recovered from the top product, n -All heptane will be taken from the sub-product. The dew point in the condenser is 67 celcius, the boiling point in the boiler is 132 celcius. If necessary, take the underwood constant of 1.22 a) Calculate the mole amount and composition of the lower and upper products per unit hour b) Calculate the minimum return flow rate value c)find the location of the supply rack if the actual number of stages is 13

Question
It is distilled at 405.3 kpa in a 100 kmol/hr liquid fed distillation tower and the mole fraction of the components is given. 90 percent of the n-pentane is separated in the top product and 90 percent of the n-hexane is recovered at the bottom. All of the n-butane is recovered from the top product, n -All heptane will be taken from the sub-product. The dew point in the condenser is 67 celcius, the boiling point in the boiler is 132 celcius. If necessary, take the underwood constant of 1.22
a) Calculate the mole amount and composition of the lower and upper products per unit hour
b) Calculate the minimum return flow rate value
c)find the location of the supply rack if the actual number of stages is 13
