Lower hydrocyclone pressure results in inefficiencies while high pressure increases the centrifugal force beyond its design specifications; this increases the cyclone wear rate. Ensuring your hydrocyclone operates in the correct pressure range enables optimum hydrocyclone operation, helping you improve downstream processing performance and ...

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.

In summary, when D o is in the optimum range, the hydrocyclone can adapt to different FSD to obtain the expected cut size by self-adjusting the LZVV and particles equilibrium radius. This method for determining the optimum range of D o is based on flow pattern characteristics and can be used as a universal tool for hydrocyclone design.
