The purpose of providing a 'catchall' in the vapor line of an evaporator is to__________________?
Correct answer: D. Arrest the entrained liquid
- A. Create vacuum
- B. Regulate the vapor flow
- C. Vent the non-condensable gases
- D. Arrest the entrained liquid
Explanation
A catchall is placed in the vapor line to remove liquid droplets carried with the vapor, preventing entrainment into downstream equipment. Vacuum creation and vapor-flow regulation require other devices.
