S3 (35/100). In a facility, its composition (mole fractions), boiling point and equilibrium constants are given below as the mixture will be separated by distillation. The column pressure is P=13.6atm. Feed (F=100molh) saturated liquid it is in the state. The entire condenser is used in the system, to obtain 98% purity propane with 98% recovery are made. Where the molar flows and a) values are constant throughout the column and there is no pentane in the peak product done. The peak temperature of the column is 40C, and the base temperature is 110C. Calculate the following: a) Peak and base product flows (molhour) and their composition ( % mol), b) The minimum number of shelves required for total backflow, c) The minimum backflow rate, d) The theoretical shelf number for the backilow rate 5
