The cylindrical hydrocyclone is widely used for coarse particle classification to suppress the misplaced fine particles in the underflow. Nevertheless, the unique flat bottom structure generates particle circulation flow, causing the misplacement of coarse particles in the overflow. A multi-stage cylindrical hydrocyclone is designed to regulate ...

Basics of a Hydrocyclone. Hydrocyclones (also referred to as cyclones) are an efficient way to separate slurries. With no moving parts, they depend on the feed pressure, or velocity, into the cyclone to generate a centripetal force. This centripetal force allows the cyclone to separate coarse or dense particles from fine particles.

With many of today's oil wells located offshore, the production of high volumes of water compared to oil poses major challenges to oil operators. The use of liquid–liquid hydrocyclone (LLHC) is one effective way to arrest these uphill problems of produced water. However, the nature of fluid flow within the LLHC device is very vital to …

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 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 …
