Question 1 of 27070

What type of oil as part of an oily-water mixture is most likely to require heating to facilitate separation in an oily-water separator?

🔍 Key Concepts

• Viscosity of different marine oils (thickness of the oil) • How temperature affects separation of oil and water in an oily-water separator • Which shipboard fuel or lube oils are normally fitted with heating systems in service tanks or settling tanks

💭 Think About

• Among the listed oils, which one is naturally the thickest and hardest to pump at ambient temperature? • On most ships, which oil do you normally find being preheated before use in engines or boilers? • Why would a high‑viscosity oil need heating to separate effectively from water compared with a lighter, more fluid oil?

✅ Before You Answer

• Identify which choice is a high‑viscosity residual fuel rather than a distillate or light lube oil • Consider which type of oil typically requires heating coils or steam heating in storage/settling tanks • Eliminate any oils that are already low enough viscosity at room temperature to separate relatively easily without heating
