Desander for Oil drilling mud. Hydrocyclones is also called cyclone separator.Hydrocyclones consist of desander(10 in. cone) and desilter(4 in. cone)are drilling rig equipments with a set of hydrocyclones that separates sand and silt from the drilling fluid. Desander is …
A desilter is the 4th phase purification equipment in the mud system. It holds similar principle and operational way as desander. However, the separation point will be finer. Depends on clients requirement, it can be set to different numbers hydrocyclone. Desilter cones are typically 4”, but some client will request 3”, 5” as well.
Here is a hydrocyclone sizing calculator with immediate access to all design equations needed for your hydrocyclone design calculation in an online XLS spreadsheet format. Based on first principles of hydrocyclone theory and equations, this quasi design software lets you enter all cyclone design parameters such as cut size, D50, D60 (efficiency calculation), graphs your results.
Centrifugal pump is used to pump the drilling fluids from mud tank into the set of hydrocyclones. KOSUN de-sander has Flexible options for 1,2 or 3 hydrocyclone desander for different capacities and desilter has flexible options for 8 or 10,12,16 hydrocyclone for different capacities.

The downhole desander is designed for ESP and PCP pump protection. These desanders are designed to extend the life and efficiency of your ESPs and PCPs. The Pump Protection Desander removes sand from the production fluids before they enter the pump.
The BRANDT™ COBRA™ Mud Conditioner uses a combination of hydrocyclones and a COBRA shale shaker to separate solids from liquid. The combination of hydrocyclone cones is dependent on the specific application and typically consist of desander cones (10- or 12-in.) and desilter cones (4-in.) properly sized to handle over 125% of the flow rate.
The standalone desander/desilter hydrocyclone unit can be assembled above linear motion shale shaker to recycle the useful drilling fluids from hydrocyclone underflow screening by fine mesh screens. Mud cleaner which combines desander, desilter and dewatering shale shaker in one unit is often used in nowadays drilling applications.
The compact inline HiPer desander, used a standalone or in combination with a HiPer desander hydrocyclone, provides continuous removal of sand and solids which protects downstream equipment from unwanted accumulation and erosion by the sand.
A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.
Desander and desilter hydrociclones are device to separate particles from drilling fluid, which is sorted by shale shaker in the first phase of solids control system. You can see in the first picture. Usage of hydrocyclone. A hydrocyclone is often used to separate drilling cuttings from drilling mud originating at a desander desilter or some other continuous source of pressurized liquid.
Drilling Fluid Desander, 5 in. Mud Desander, Hydrocyclone, 1-1/4 in. Inlet and 2 in. Outlet
Nov 17, 2016· Hydrocyclones are arranged with the unit of larger cone size upstream of the smaller unit. A separate tank is needed for each size unit. Generally, a desander and a desilter manifold are available as part of the rig equipment. Hydrocyclones should process all drilling fluid entering their suction compartments independently of the drilling-fluid circulation rate. …
The hydrocyclone is oriented so that the wide opening is at the top and the narrow opening at the bottom. Hydrocyclones are designed according to the efficiency of solids removal required and the flow rate of the product stream. A typical waste water desander will …
Aug 08, 2018· One of the only and most elementary items of solids-control instrumentality is that the desander. A desander relies on the principle of the hydrocyclone. the essential plan is: Pump mud into the fringes of the highest of a round shape. The mud whirls around quicker and quicker because it travels down the wall of the cone.
Hydrocyclones are cono-cylindrical in shape, with a tangential feed inlet into the cylindrical section and an outlet at each axis. The outlet at the cylindrical section is called the vortex finder and extends into the cyclone to reduce short-circuit flow directly from the inlet.
Suez Oil & Gas Systems' award winning CYCLONIXX ® Wellhead Desander Hydrocyclones offer a solids-separation technology specifically aimed at multi-phase well streams that is suitable for all wellhead gas/liquid ratios from liquid to gas. Our hydrocyclones are designed to withstand extremely harsh wellhead conditions including exposure to very high pressures, elevated temperatures ...
10 INCH INLINE DESANDERS. 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. The underflow can be discarded or directed onto a vibrating screen for further processing.
Sep 15, 2018· The parameters required to assess the desanders were very clear. A set of questionnaires were sent to various vendors and service providers having desander service for separation of sand with following details: Details on the hydrocyclone technology and accumulator depending upon company’s application requirement. The below parameters were considered as one …
Apr 25, 2018· Hydrocyclone is core part of mud cleaner (desilter, desander). Hydrocyclones are a cost-effective method of removing many of the fine solids missed by the shaker in unweighted muds. Hydrocyclones separate solids from fluid by using centrifugal force to cause solids to be settled from the fluid. There are no moving parts. Centrifugal force is created […]
Desilter and desander unit mud recycling system is widely used in pilling project recent years. This month, DC Machinery designed a set of 250m3/h desilter unit mud recycling system for a Singapore clients. Desilter Hydrocyclones are used to provide efficient and reliable separation of sand and solids from Produced Water, Condensate and/or Gas streams.
the desander, which causes the fluid to spin. Strong centrifugal forces are generated by the spinning motion, causing the solids and liquid to separate. The centrifugal force generated in a hydrocyclone varies over its length and may reach a maximum of 2,000 g. …
Hydrocyclones Desander D.02 Introduction Desander Hydrocyclones are used to provide efficient and reliable separation of sand and solids from Produced Water, Condensate and/or Gas streams. They have proven to be a valuable part of many Oil and Gas production facilities, by providing: • High Efficiency Solids Removal, • Compact, small footprint,
Desander removes the abrasive solids from the drilling fluids which cannot be removed by shakers. Normally the solids diameter for desander to be separated would be 45~74μm, and 15~44μm for desilter. A centrifugal pump is used to pump the drilling fluids from mud tank into the set of hydrocyclones…
The compact inline HiPer desander, used a standalone or in combination with a HiPer desander hydrocyclone, provides continuous removal of sand and solids which protects downstream equipment from unwanted accumulation and erosion by the sand.
Page 3 of 19 catsup. In the oil and gas industry solid-liquid cyclones are used in drilling operations, while only recently has this technology found significant use in oil and gas production operations2. By definition, a “desander” is a solid-liquid hydrocyclone that operates with an enclosed
Small diameter (12 to 100 mm), high efficiency desander cyclone liner are typically made of ceramic materials to provide excellent erosion resistance. If the particles to be removed are in excess of 50 microns then the use of single large diameter hydrocyclones (>150mm) becomes an option.
Cyclonic Desander. Cyclonic desanders are designed for the mixture of crude, water and natural gas, in which there are some produced sands and particles involved, and to be removed, and manufactured in a range of different sizes, which can be accommodated in a highly compact pressure vessel, for different removing efficiency or purposed.
