The benzene compound was selected by conducting the Aspen Plus study as described in the following paragraph. Please, make sure the compound of your choice is available in the Aspen Plus program. Since your chosen compound is in the vapor phase, cool a stream of pure component using two interstage coolers according to the following specifications: $1.$ The stream from the first refrigerant should be in the vapor phase but the temperature should be reduced. $2.$ In the second stage, the outgoing stream is expected to be in liquid phase only. more details $1.$ The feed enters the first coolant at a pressure of $10$ bar and a temperature of $40\backslash$deg C above its boiling point at the given pressure. $2.$ The pressure must be maintained at $10$ bar for all refrigerants. $3.$ The feed mass flow rate should be set to $500$ kg$/$h$.$ Questions: $1.$ Use Aspen Plus software to obtain the data needed to draw PV$,$ TV and PT diagrams. $2.$ Select a suitable program to draw PV$,$ TV and PT diagrams from the data you obtained in Question $1.$ Please explain each of the diagrams. $3.$ Using the graph you obtained above, determine the inlet and outlet temperatures of both coolers. $4.$ Simulate the process in the Aspen Plus environment. $5.$ What are the power requirements for each of the chillers? $6.$ How can you verify the results obtained from your Aspen Plus simulation. $7.$ Explain the effect of increasing the pressure in each of the refrigerants to $20$ bar.Exampleand water vapor.

Figure $5.$The simulation

After the simulation, we determined the power requirement of each heater:

The power of the Heater $1$ was $P=-1\mathrm{.}845kW$

The power of the Heater $2$ was $P=-84\mathrm{.}7KW$
