The Desander works on a differential of specific gravities of the solid from the liquid. Normally, removing 40 micron and above solids when high (98%+) efficiencies are required. For produced water applications, typical efficiencies are 98% for 74 micron and larger particles, 95% for 73 to 40 micron particles, 84% for 39 to 20 micron particles ...

E ToreTrap Desander The ToreTrap system is a highly efficient single vessel desander designed to remove sand from an inlet fluid stream with minimal disruption to the flow or process. Solid/liquid hydrocyclones separate sand and/or solids from the liquid stream. The Tore fluidizer, installed at the base of the vessel, allows online solids ...

The desander cyclone displaces sand below the pump, sending it to the tailpipe, and the sandguard which is above the ESP captures sand fall back from the tubing. Benefits. Beyond simply removing sand, there are multiple benefits to having a downhole desander in place. Amongst some of the most prominent are:

Desilters. A desilter uses smaller hydrocyclones (usually 4″ or 5″ I.D.) than a desander and therefore, generally removes smaller particles. 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.

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.

processes that allow the solids to become oil wet, thereby creating an oil layer on the sand particle. Removing the sand ahead of the separators prevents oil adsorption. Second, proper operation of a multiphase desander ensures that the collection vessel (accumulator) is pre-filled with clean water after each purge cycle.
