Question

A distillation column is used to separate 500 kg /h of a mixture containing 50 wt% benzene (C6H6) in toluene
(C7H8), to give top product of 88 % mole benzene and 75% mole toluene waste (at bottom).
1. Calculate the mole flow rate, mole fraction and mole percentage of each stream in the (F, D & W) around
the column? All results should be tabulated in the Table below.
2. Calculate the heat removed by condenser?

Given the following data;
The enthalpy of feed stream is = - 900.00 kJ/kgmol
The enthalpy of distillate is = 800.00 kJ/kgmol
The enthalpy of waste is = 3000.00 kJ/kg mol
The heat added by boiler is = 4500.00 kJ /h
Given:
The molar mass of Carbon is 12
The molar mass of Hydrogen is 1
