Computational fluid dynamics and experimental
A hydrocyclone is one of the most important pieces of equipment for a desanding system. In this work, the standard hydrocyclone was taken as the research object to perform an external characteristic experiment with similar parameter criteria.

The smaller cones enable a desilter to make the finest particle size separation of any full flow solids control equipment—removing solids in the range of 15 μm and larger.Desilters an overview ScienceDirect Topics

Small diameter (12 to 100 mm), high efficiency desander cyclone liner are typically made of ceramic materials to provide excellent erosion resistance. If the particles to be removed are in excess of 50 microns then the use of single large diameter hydrocyclones (>150mm) becomes an option.Technology. HiPer desanders and HiPer desander hydrocyclones can be used to remove sand and solids at several stages in the typical oil and gas processing facility, for instance upstream of main production separators or at the entry to produced water treatment system deoiling hydrocyclones.

Removing solids from water PetroWiki
For general comparison information, in a produced-water-treatment application, a 0.5-in. (10-mm) desander will have a separation size of 5 μm, while a 30-in. (750-mm) desander will have a separation size of 100 μm. The practical limit for sand separation from water by a hydrocyclone is 10 μm.1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.The Top 5 Things You Need To Know About Hydrocyclones

1. n. [Drilling] A hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers and degassers, but before the desilters or mud cleaners. A volume of mud is pumped into the wide upper section of the hydrocylone at an angle roughly tangent to its circumference. AseProcess Desanding Hydrocyclone (Desander) is a fit-for-purpose solid-liquid cyclone designed to remove sand from produced water streams. This technology is most commonly installed on the outlet of a three-phase or FWKO separator.

Experimental and mechanistic study of the surfactant
In 1996, the first commercial wellhead hydrocyclone desander was put into use at the Brent D platform in the North Sea. It was used for sand removal in the tubing cleaning process. The operating pressure drop was <500 kPa, and the average separated particle size was as low as 20 μm (Rawlins, 2017). In the South Pass 78A platform in the The desander is derived from the mineral processing hydrocyclone, thus is a subset of that technology.

[PDF] Study on the Interaction of a Flooded Core Hydrocyclone
The flooded core solid-liquid hydrocyclone, termed a desander, is used extensively in the oil and gas industry to separate sand and solids from produced water. A desander comprises a standard solid-liquid hydrocyclone with an accumulation chamber connected to the apex. The accumulation chamber prevents formation of an air core. Thus, the hydrocyclone 1. n.
