A company wants to decide whether to heat chlorobenzene or nitrobenzene through the shell, in a heat exchanger with the following characteristics:
35 in. ID tubular heat exchanger
Contains 800 tubes of 0.75 in outside diameter, 12 in length, in a 1 in pitch square arrangement.
The deflector plates used are 25% of the standard (fb= 0.1955) and are separated from each other by a distance of 12 in.
If the fluid enters the shell at an overall temperature of 60 F with a flow rate of 100,000 lb/h. Also, the outer surfaces of the tubes are at 140 F.
What would be your recommendation?
Note: Cp, eileneglicol = 0.4 BTU/lbF
Cpnitrobenceno = 0.42 BTU/lbF
