Hydrocyclones
In a hydrocyclone, a slurry enters through a tangential inlet, giving rise to a vortex in the stationary body. The particles and fluid are accelerated centrifugally and separation occurs in the radial direction. Denser materials migrate to the outer wall of the hydrocyclone chamber, while less dense materials move toward the inner axis.

HYDROCYCLONES
The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

The Science and Technology of Hydrocyclones
The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a hydrocyclone.
