What is the vessel used to treat or separate water-oil emulsions?

• A. Distillation column
• B. Treater
• C. Reactor
• D. Separator

Answer: (B)

Treating water-in-oil emulsions requires a unit that can chemically break the emulsion and then let the water separate from the oil. A treater is designed for this role: it heats the incoming crude, injects demulsifying chemicals to destabilize the water droplets trapped in the oil, and provides a residence area where droplets can coalesce and settle as free water. This prepares the crude for downstream separation and transport by removing most of the water and salts before it reaches pipelines or further processing. A separator, by contrast, mainly uses gravity to separate phases after some conditioning, but it’s not specifically focused on breaking emulsions with chemicals. Distillation columns separate components by boiling points, and reactors are for chemical reactions, not emulsion treatment. So the vessel that best fits the purpose of treating and breaking water-oil emulsions is the treater.
