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 flow pattern in a hydrocyclone ...

Solid/liquid separation performance of hydrocyclones with …

The coalescence and breakup-dominated regions were investigated in different designs of de-oiling hydrocyclone using the E-L approach. Examining different designs shows that large changes in cone angle create a region of high turbulence and enhance droplet breakup. It can be concluded that the Sauter mean diameter of droplets …

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 …
