One tonne per hour of liquid benzene at 20C, atmospheric pressure is vaporised using superheatedsteam at 5 bar, 250C that leaves the system as saturated water. The temperature of benzene vapouris 110C.

(a) Draw a schematic of the process unit to be used showing all streams and the informationavailable.

(b) Using the Physical Property data file (available from Minerva/ Energy Balance folder)find and show the data required for solving the energy balance of the benzenevaporiser.

(c) Draw the inlet-outlet enthalpy table used for the energy balance of the process of benzene vaporisation.

(d) Calculate the rate of the superheated steam used
