MI-Swaco Desander

The M-I SWACO D-SANDER* Models 2-12 and 3-12 are designed for high-volume continuous removal of sand and abrasive cuttings from drilling fluids — 95% of all particles to 74 microns and more than 50% of particles to 40 microns. The D-SANDER features your choice of two or three 12-in.- (304.8-mm-) diameter replaceable, wear-resistant, polyurethane hydrocyclones and quick-release stainless steel clamps for simplified changeout. They are a fundamentally important piece of a rig’s complete solids control package. They also help limit repair and replacement of pump parts damaged by abrasives-laden drilling fluids.

NOV Brandt Desander

Desander, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the desander is, the greater the amount of fluid it is able to process and the larger the size of the solids removed. Desanders (10 in. ID) are able to remove roughly 50 percent of those solids within the 40-50 micron range at a flow rate of 500 gallons per min (gal/min), while desilters (4 in. ID) are able to remove approximately 50 percent of those solids within the 15-20 micron range at a flow rate of 60 gal/min. Microfine separators (2 in. ID) are able to remove around 50 percent of those solids within the 10-15 micron range at a flow rate of 15 gal/min. Desanders are typically positioned next-to-last in the arrangement of solids control equipment, with mud decanter centrifuges as the subsequent processing unit. They are preceded by gas busters, gumbo removal equipment (if utilized),fluids  shale shakers, mud conditioners (if utilized) and degassers.

NOV® Brandt® manufactures desander in Conroe, Texas, USA. desanders are typically configured to meet the specifications demanded by the application. Usually, the desired flow rate determines the configuration of the cones, including the size utilized. desanders are just one of the many solids control and waste management offerings that NOV Brandt supplies to the oil and gas industry. NOV Brandt’s Quality Management System is ISO 9001-2000 certified.

  1. ZQJ series desander and desilter for solids control system Says:

    [...]  Desanders and desilters are drilling rig equipment with a set of hydrocyclones that separates sand and silt from the drilling fluid. Desander is installed after shakers and degasser but before desilter. Desander removes those abrassive solids from the drilling mud which cannot be removed by shakers. Desilting is employed in dams and lakes. [...]
