?Two schemes are proposed for the reduction in pressure of ethylene gas at 375 K and 18
Chapter 7, Problem 7.56(choose chapter or problem)
Two schemes are proposed for the reduction in pressure of ethylene gas at 375 K and 18 bar to 1.2 bar in a steady-flow process:
(a) Pass it through a throttle valve.
(b) Send it through an adiabatic expander of 70% efficiency. For each proposal, determine the downstream temperature, and the rate of entropy generation in \(J \cdot mol^{−1} \cdot K^{−1}\). What is the power output for proposal (b) in \(kJ \cdot mol^{−1}\)? Discuss the pros and cons of the two proposals. Do not assume ideal gases.
