Wellhead desanders are utilizes in production wellhead. It consists of a single cyclone insert housed inside a vessel operating at the appropriate wellhead design pressure. Wellhead fluids enter the cyclone's tangential inlet, which forces the mixture to spin. Both gas and liquid migrate towards the center of the cyclone when exposed to the strong centrifugal forces.  Solids are separated from the gas and liquid and fall into an accumulator vessel. These efficient units protect downstream equipment from erosion.
