Q

Sludge tanks are used in an oil lubricating system to receive __________.

🔍 Key Concepts

• Function of sludge tanks in a lube oil system • Difference between sludge/contaminants and usable lube oil • What the lube oil purifier/clarifier removes from the system

💭 Think About

• Think about what kind of material you would NOT want to send back into the main lube oil system, but still need to collect safely. • Which component in a lube oil system actually separates out water, dirt, and other foreign matter from the oil? Where does that separated material go? • Which answer choices describe oil you plan to REUSE in the system vs. waste/contaminated liquids you plan to DISPOSE of or treat as sludge?

✅ Before You Answer

• Identify which options describe contaminated or separated waste rather than clean or reusable oil. • Check which choice best matches the discharge from a lube oil purifier or clarifier (think: what comes out of the sludge outlet, not the clean oil outlet). • Eliminate any answer that implies all normal circulating oil or fresh makeup oil is going to the sludge tank. Those normally go elsewhere.
