Pump Models in Simulators

In a toluene hydrodealkylation process, 25,000 Ib/hr of toluene feed is pumped from 75°F and 30psia to 570 psia. Use a process simulator to compute the capacity in gpm, the pump head in feet of tolueM, the exit temperature, and brake horsepower (BHp) for  

Using the SRK equation of state for thermodynamic properties, the following results are obtained 

The temperature rise is very small even for the 75% efficiency case. The pump head is well above the limit of 500 ft for a single-stage centrifugal pump. Therefore, a multistage centrifugal pump would be required.
