Brandt Hydrocylones VS Derrick desander VS Mi-Swaco desander

Nov. 14, 2009 - PRLog -- Derrick,and MI-Swaco,and the NOV brandt are all big companies for solids control,desander,and hydrocyclones are one the equipments.

Brandt Hydrocyclones intro.
Hydrocyclones are simple mechanical devices, without moving parts, designed to speed up the settling process. Mud pump pressure is used to generate centrifugal force, which separates heavier solids from lighter solids. Hydrocyclones consist of desanders (10 in. cone), desilters (4 in. cone) and microfine separators (2 in. cone). Typically, these units are placed after the shale shakers, however, they can also be mounted above a shale shaker to create a mud conditioner.

Hydrocyclones, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the hydrocyclone 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. Hydrocyclones are typically positioned next-to-last in the arrangement of solids control equipment, with centrifuges as the subsequent processing unit. They are preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud conditioners (if utilized) and degassers.

NOV® Brandt® manufactures hydrocyclones in Conroe, Texas, USA. Hydrocyclones 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. Hydrocyclones 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.


Derrick desander

   * Sand size solids removal (40 - 100 microns)
   * 500 gpm per cone at 75 feet of head
   * Variable size apex inserts

Derrick desanders make separations between 40 and 100 microns and offer the flexibility of mounting either one, two, or three 10" desander cones over a cone underflow pan. Each 10" hydrocyclone processes 500 gpm at 75 feet of head, allowing for a maximum capacity of 1500 gpm. The underflow can be discarded or directed onto a vibrating screen for further processing. Derrick desanders are also available in vertical or inclined manifold stand-alone models, or for inclined mounting on Derrick shakers.

MI-Swaco D-SANDERs

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.

The D-SANDER is available in two configurations…slant-mount and space-saving vertical-mount with single, dual or triple long-lasting compounded polyurethane cones.

From Brandt,Derrick,MI-swaco introduction for desander or hydrocyclones,we find MI-Swaco and Derrick gives a good discription better than Brandt.
