Hydrocyclone separators, sometimes called enhanced gravity separators, use centrifugal force to remove oil droplets from oily water. As shown in Figure 7-16, static hydrocyclone separator consist of the following four sections: a cylindrical swirl chamber, a concentric reducing section, a fine tapered section, and a cylindrical tail section.

Hydrocyclone is a kind of using centrifugal force field equipment, in addition to a pump, it needs no mechanical transmission components, and inexpensive,compact, widely used for solid-liquid separation process. It works like acentrifuge separation factor, but with a much larger. The most important in the cyclone flow as the basic vortex and the two vortex.…

marily to assist in achieving the target oil vapor pressure, and the oil-dehydration target. In the deepwater GOM, oil/water separation tends to be focused toward the end of the gas/oil/water-separation process. The produced water may be processed through a hydrocyclone. However, in some facilities, a hydrocyclone is installed but not used.

Hydrocyclone is also called cyclone separator, Hydrocyclone include hydrocyclone desander (10inch cone) and hydrocyclone desilter (4inch cone), which is used to separate sand and silt from the drilling fluid.A hydrocyclone has two exits on the axis: the smaller on the bottom (underflow or reject) and larger at the top (overflow or accept). The underflow is generally the denser or thicker ...

Hydrocyclone, as in Fig. 1, is the device that is widely used for the separation of materials normally in the form of solid particles. In drilling rig business, it's mainly used in solids control field. it's main part of desander and desilter. The device can offers effective solid removal in a compact package comparing with other methods.

Toro hydrocyclone separators are designed for the most challenging of agricultural, greenhouse and nursery applications. These manual filter units are ideal for removing large volumes of suspended material such as sand or other heavy debris. Water enters via the inlet creating a spiral flow. Centrifugal force separates the dirt particles from the water and pushes them towards the walls of the ...
