🔍 Key Concepts

• Trace the flow path of brine and air/vapor through the distilling unit in the illustration • Identify where the ejectors (air ejector and brine ejector) take suction from and where they discharge • Note which lines are small-diameter connections versus main feed or jacket water lines

💭 Think About

• Follow pipe J from one end to the other on the rear view and relate its location to the side-view internals; what space inside the shell is it connected to? • Compare the positions of the brine ejector and air ejector in the lower piping cluster: which one would logically need a line going up to the top of the shell to remove something? • Ask yourself: is pipe J more likely to be carrying liquid (brine or feed) or non‑condensable gases/air, based on where it starts and ends?

✅ Before You Answer

• Confirm which component in the lower assembly is labeled as the air ejector and which is the brine ejector • Verify whether pipe J terminates at a gauge/vent at the top of the shell or at a liquid outlet near the bottom • Make sure you can distinguish the feed water supply and jacket water supply manifolds from the smaller auxiliary lines before choosing your answer
