How do you choose a hydrocyclone?
The first option for selection would be based upon the lowest capital cost and the fewest number of operating hydrocyclones. Based on this selection criteria and the feed conditions, it would be customary to offer seven operating 500 mm diameter cyclones to meet these performance requirements.
How big is a hydrocyclone?
While early workers experimented with cyclones as small as 5 mm diameter, commercial hydrocyclone diameters currently range from 10 mm to 2.5 m, with separating sizes for particles of density 2700 kg m−3 of 1.5–300 μm, decreasing with increased particle density.
What is hydrocyclone classification?
Hydrocyclone is a classification equipment widely used at present because of its high classification efficiency, small floor space and low price. It can be applied in the mineral classification, sewage treatment, slurry concentration, desilting and oil and water separation, etc.
How do you calculate pressure drop in hydrocyclone?
The solution of the equation 3 is: P = D* Vt * ln (r) + C (4) This solution gives the pressure distribution in the cyclone flow field. The cyclone pressure drop is a function of the cyclone dimensions and its operating conditions.
What is cut point in hydrocyclone?
As stated earlier, the cut point is related to the inside diameter of the. hydrocyclone. For example, a 12-inch cone has a D50 cut point for lowgravity solids in water of approximately 60 to 80 microns; a 6-inch cone, around 30 to 60 microns, and a 4-inch cone, around 15 to 20 microns (Table 1.).
What is cut size of a hydrocyclone?
The cut-size, indicated as 50, is defined as the size of the particle in the Particle Size Distribution (PSD) that has a 50% probability of reporting to either the underflow or the overflow of the hydrocyclone (Bradley, 1965).
What is a hydrocyclone in oil and gas?
Hydrocyclones are devices used to treat produced water in the petroleum industry. These gadgets are employed especially at offshore fields, due to restrictions of charge and space. Several factors may affect the performance of the oil/water separation by hydrocyclones.
