Question

A distillation column is used to separate 280 kg /h of a mixture containing 30 wt% Propanol (C3 H8 O) in Octanol

(C8 H14 O), to give top product of 83% mole Propanol and 67% mole Octanol 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 The enthalpy of distillate is The enthalpy of waste is
The heat added by boiler is

Given:
The molar mass of Carbon is 12 The molar mass of Hydrogen is 1 The molar mass of Oxygen is 16

= -970 kJ/kgmol = 450 kJ/kgmol = 4000 kJ/kgmol = 3200 kJ /h
