The purpose of providing bleed points in the evaporator is to__________________?
Correct answer: C. Facilitate removal of non-condensable gases
- A. Admit the feed
- B. Remove the product
- C. Facilitate removal of non-condensable gases
- D. Create vacuum
Explanation
Bleed points allow trapped air and other non-condensable gases to escape from the evaporator. These gases otherwise form an insulating layer and reduce the effective heat-transfer rate.
