Two types of oil separators are:

Two types of oil separators are:

• A. API and the Parallel Plate Separator
• B. Centrifuge and Filtration
• C. Coalescing Separator and Demister
• D. Gravimetric Separator and Settling Tank

Answer: (A)

Oil-water separation relies on gravity and the way droplets behave in a settling environment. The two named types are a classic gravity separator defined by a standard design and a plate-based gravity separator that increases contact area to boost coalescence. The API separator is a widely used standard for removing free oil from water. It relies on droplet rise and surface skimming in a large tank, letting oil collect at the top while the cleaned water exits from beneath. The Parallel Plate Separator, on the other hand, uses a stack of plates inside the separator to greatly increase the surface area the droplets encounter. That added area encourages smaller oil droplets to collide and coalesce into larger droplets, which then settle out more easily. Together, they represent two distinct approaches to achieving oil separation: a traditional tall-tank gravity design and a plate-packed gravity design. The other options mix technologies that aren’t both standard oil-separator types, or pair items that aren’t oil-separation devices, so they don’t fit as the two primary types of oil separators.
