You are responsible for a high temperature process that produces two exhaust streams, stream
A at 600 ıC, 10 bar, with molar flow rate 100 mole/s; and stream B at 200 ıC, 20 bar, with molar flow rate
50 mole/s. A young engineer in your team comes to you with an idea to utilize these streams to produce
heat and work which will save costs in your process. She quickly puts together a sketch for a process that
produces 220 kW of heat, 1700 kW of work, and delivers the exhaust gases as a single stream at 1 bar. The
heat will be used to produce saturated steam at 1 atm by boiling the saturated liquid.

a) What is the temperature of the exit stream?
b) Should you take this idea to your superiors for further discussions?
c) Could you use the heat from this process to boil water at 10 bar?
Additional information: Assume the exhaust gases can be treated as an ideal gas with CP D 30 J=mole K.
