Q.3 A solution containing 50% ethylbenzene (A) and 50% styrene (C) is to be separated at 25°C at a rate of 1000 kg/h into products containing (on a solvent-free basis) 10% and 90% styrene, respectively, with diethylene glycol (B) as solvent. Determine the number of theoretical stages and feed location if the extract reflux ratio is 8.55 kg reflux/kg extract product. Equilibrium data are given below.
