The Top 5 Things You Need To Know About Hydrocyclones

1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.

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 …
