Of the processes proposed in Probs. 7.50 and 7.51, which would you recommend?
Liquids (identified below) at 25°C are completely vaporized at 1(atm) in a
countercurrent heat exchanger. Saturated steam is the heating medium, available at
four pressures: 4.5, 9, 17, and 33 bar. Which variety of steam is most appropriate for
each case? Assume a minimum approach ΔT of 10°C for heat exchange.
