Drilling fluids Desander knowledge

Dec. 14, 2009 - PRLog -- Desander separator fulfill separation on drilling mud large drilling cuttings. It is second class solids control equipment. Various size desander cones are functionally identical, with the size of the cone determining the size of particles the device removes from the mud system. http://www.gnsolidscontrol.com/desander/

A hydrocyclone separator that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers, but before the desilters. A volume of mud is pumped into the wide upper section of the hydrocylone at an angle roughly tangent to its circumference. As the mud flows around and gradually down the inside of the cone shape, solids are separated from the liquid by centrifugal forces. The solids continue around and down until they exit the bottom of the hydrocyclone (along with small amounts of liquid) and are discarded. The cleaner and lighter density liquid mud travels up through a vortex in the center of the hydrocyclone, exits through piping at the top of the hydrocyclone and is then routed to the mud tanks and the next mud-cleaning device, usually a desilter.

Desander comes from different areas hold different capacity. Following one is a common and typical one. http://oilfield.gnsolidscontrol.com

Desander, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the desander is, the greater the amount of drilling fluids it is able to process and the larger the size of the solids removed. Desander (10 in/254 mm Cone) are able to remove roughly 50 percent of those solids within the 40-50 μm (micron) range at a flow rate of 500 US gallons per minute (0.032 m3/s) (USgal/min), while desilter (4 in/101.6 mm Cone) are able to remove approximately 50 percent of those solids within the 15-20 μm (micron) range at a flow rate of 60 US gallons per minute (0.0038 m3/s). Micro fine separators are able to remove around 50 percent of those solids within the 10-15 μm (micron) range at a flow rate of 15 US gallons per minute (0.00095 m3/s). Desander is typically positioned next-to-last in the arrangement of solids control equipment, with decanter centrifuge as the subsequent processing unit. Desander are preceded by gas busters, gumbo removal equipment (if utilized), shale shaker, mud cleaner (if utilized) and vacuum degasser.Desander is widely used in oilfield drilling.

GN Desanders hold common parameters like that: Capacity including 40m3/h(176GPM) , 80m3/h(352GPM),  90m3/h(396GPM) , 180m3/h( 792GPM) , Cone size is 8”, 10”; separation size: ≥47μm; etc. specs.
