A pharmaceutical plant requires 3,750 kW of electric power and high-quality steam at 107oC, with a mass flowrate of 2.2 kg/s, for an operation of 7,200 hour per year.

Two options are under consideration:

Option 1 A single boiler generates steam at 2.0 MPa and 320 degree C, supplying a turbine that exhausts to a condenser at 0.007 MPa. Steam is extracted from the turbine at 107degree C, returning as a liquid to the boiler after use.

Option 2 A boiler generates steam at 2.0 MPa and 320degree C, supplying a turbine that exhausts to a condenser at 0.007 MPa. A separate steam boiler generates the required steam at 107degree C, which is returned as a liquid to the boiler after use.

Evaluate the 2 options and provide your recommendations.
