Question 1 of 27070

The temperature of emulsified lubricating oil entering a purifier from a preheater should range between __________.

🔍 Key Concepts

• Effect of temperature on viscosity of lubricating oil • Purpose of a purifier (centrifuge) in separating water and sludge from lube oil • How too low or too high temperature affects separation efficiency and risk of oil breakdown

💭 Think About

• Which temperature range will make the oil thin enough to separate water and impurities easily, but not so hot that it damages the oil? • Think about typical lube oil operating and storage temperatures—would you heat emulsified oil close to its normal system operating temperature, or well below/above it? • How would very high temperatures affect the additives and possible flash/fire safety when sending oil to a purifier?

✅ Before You Answer

• Verify the normal recommended inlet temperature range for lubricating oil purifiers in standard marine engineering texts or manufacturer manuals • Check how viscosity vs. temperature curves for lube oil look around 110°F, 140–150°F, 160–180°F, and 190–210°F • Make sure the chosen range improves separation efficiency without risking oil oxidation or additive breakdown
