Redo Problem 4.38 using Aspen Plus.

Problem 4.38

Atmospheric air is to be compressed and heated as shown in the figure before being fed into a chemical reactor. The ambient air is at 20^◦C and 1 bar, and is first compressed to 5 bar and then heated at constant pressure to 400^◦C. Assuming air can be treated as a single-component ideal gas with C^∗_V = 21 J/(mol K), and that the compressor operates adiabatically and reversibly,

a. Determine the amount of work that must be supplied to the compressor and the temperature of the gas leaving the compressor.

b. Determine the heat load on the heat exchanger.

20C, 1 bar Ambient air 5 bar Heater 400C, 5 bar
