What type of heat exchanger is limited to low heat duty?
A. Reboilers
B. Spiral-wound
C. Double-pipe
D. Plate-and-frame
A. Incorrect. Reboilers are commonly used on distillation towers or regenerators.
B. Incorrect. Spiral heat exchangers offer high reliability and are good for operations with high fouling potential, such as slurries.
C. Correct. Double-pipe exchangers are limited to low heat duty, where the change in temperature (?T) between the two fluids is not large.
D. Incorrect. Plate-and-frame exchangers are usually used with clean (solids-free), nontoxic materials, and they operate at fairly low pressures and temperatures.
