HYDROCYCLONE
Hydrocyclone sizes are designed arbitrarily by the inside cone diameter at the inlet. By convention, desanders have a cone diameter of 6 inches and larger; desilters have internal diameters smaller than 6 inches. Normally, discharges from the apex of these cones are discarded when used on unweighted drilling fluids. Prolonged use of these …

What is a hydrocyclone used for and how does it work?
A hydrocyclone is a simple cone-shaped cylindrical container that has no moving parts. It is used to separate or "cut" solid particles in a liquid stream by size and density. What does a hydrocyclone look like? A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading ...

Hydrocyclone Technology: Then and Now
Closely related to the centrifuge device, whose separation force is achievable by rotation of the entire equipment, the hydrocyclone instead depends upon the movement of the centrifugal forces within the fluids to allow for adequate particle separation. In 1891, E. Bretney patented the first hydrocyclone, and from this time through 1948, a ...

High Efficiency Liquid/Liquid Hydrocyclone
tapered shape of the hydrocyclone liner, and the spinning motion creates a centrifugal force up to 4000 G's which causes the oil and water to separate rapidly. The oil forms a core at the axis of the hydrocyclone and is forced out via a centered opening at the inlet end of the hydrocyclone liner. The result is a simple but effective, and very
