To make an industrial solvent, benzene (C6H6) is provided at a molar flow rate of 1140 kgmol/hr. Phenol (C6H6O) is also added to the benzene at a rate of 67.25 kgmol/hr to enhance the solvent properties. Finally, it is necessary to add Toluene (C7H8) so that the final solvent production rate (mass flowrate) is 115,000 kg/hr. At what mass flow rate should the Toluene be added?

Distillation

Distillation is a process/technique to separate more volatile components from less volatile components using the principle of relative volatility. In chemical engineering, distillation is one of the most common and important topics that is involved in almost every industry and process.
