Where can the pass partition of an exchanger be found?

• A. On the channel head
• B. Inside the shell
• C. On the manway cover
• D. At the exchanger outlet

Answer: (A)

The pass partition is located in the channel head. In a multi-pass exchanger, the flow on the tube side is split into several passes as it moves through the tube bundle, and the divider that creates those separate passes sits right in the channel head where the flow enters and is redirected into the tubes. This placement lets the inlet flow be split into multiple, distinct passes and then collected back toward the outlet. The shell interior, the manway cover, or the outlet aren’t the places that create or house these divided flows.
