🔍 Key Concepts

• Corrosion prevention in distilling/evaporator plants during lay-up • Effect of trapped moisture and oxygen on steel surfaces • Difference between short-term securing and extended out-of-service periods

💭 Think About

• Think about what causes the most corrosion inside a steel evaporator when it is not operating for a long time. • Consider whether it is better for the internal surfaces to be wet or dry during extended lay-up. • Ask yourself what happens if you seal a metal tank that still has some moisture versus allowing it to be open in a controlled way.

✅ Before You Answer

• Identify which choice would minimize long-term corrosion of internal metal parts. • Eliminate any option that obviously keeps saltwater in contact with metal surfaces for long periods. • Decide whether excluding air completely is realistic, or whether some dry, ventilated condition is safer.
