The Effect of the Pressure Drop Ratio on the Performance

In this paper, a novel dynamic de oiling oil water separator was proposed, and through Computational Fluid Dynamics (CFD) simulation, the effects of the pressure drop ratio on the separation efficiency and the split ratio were analyzed. The results shows that the separation efficiency initially increased and then held steady as the pressure drop ratio increased, while the split ratio exhibited

Hydrocyclone Feed Pump amp; Pressure PSI vs Operating Parameters

For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.

Thus, the lower the flow rate, the lower the pressure drop and the coarser the separation. A minimum flow must be maintained through each cone to create the required pressure drop and rotary motion to ensure separation. Typically, hydrocyclones are operated with a 2550 psi (140275 kPa) pressure drop.
