Question:
A chemical reactor requires heated air at 375oC and 20 bar. Consider a process that takes air at 20o C and 1bar to produce the desired heated and compressed air with a flow rate of 1 mol/sec. This is done using a compressor then a cooler or heater. Assume that air can be modeled as an ideal gas with a constant volume heat capacity of 21 J/(mol K). The compressor operates adiabatically.
(a) If the compressor is reversible, what is the exit temperature of the gas and the work needed to compress air?
(b) What is the heat requirement for the heater based on part a?
(c) Repeat parts a and b for an 70% efficient compressor.
