🔍 Key Concepts

• Trace the flow paths of seawater, brine, and distillate in the distilling plant shown in MO-0110. • Identify which heat exchanger has seawater on one side and fresh distillate/vapor on the other. • Consider where a pressure difference would force seawater into the distillate side if a joint or gasket leaked.

💭 Think About

• Look at the labeled components and decide which unit is acting as the evaporator (heater/boiler) and which is the condenser (cooler). • Ask yourself: in which of these units is seawater actually used as cooling water, and what would happen if the cover or head bolts on that unit were loose? • Think about which side (seawater vs. vapor/distillate) normally runs at the higher pressure, and how that affects the direction of leakage through a loose-bolted joint.

✅ Before You Answer

• Verify which exchanger in the illustration is marked as the condenser handling seawater cooling. • Confirm which exchanger’s loose bolts would allow seawater to leak directly into the fresh-water/distillate space instead of to the outside. • Make sure the option you pick explicitly involves seawater in contact with the condensing/distillate side, not just the heating side of the system.
