Hydrocyclone separators and mud cleaner configuration

Feb. 4, 2011 - PRLog -- Hydrocyclone Separator and mud cleaner common ground

The hydrocyclone desander separator. We only call it desander. Usually, it is combined desander cone and underset shaker. But many users only inquire desander cone. It takes advantage of cyclone separation principle.

Then separate particle sized 47~74microns out. Subsequently, desilter holding same principle and separate particle sized 15~46 microns

Mud cleaner and desander/desilter will be selected as one. And under set shaker of mud cleaner can choose rather fine screen. Such as 300 mesh. This will lead left particle size much small and decrease drilling fluid weight as well as decrease the decanter centrifuge load.

How to design desanders and desilters hydrocyclone separator

Each hydrocyclone (desander or desilter) feed manifold requires its own pump and motor (dedicated pumps). Hdrocyclone discharge indicates solids overloading and the need to either add additional equipment, reduce penetration rate, or accept the contamination of the drilling fluid with recirculated drilled olids.


Issues affect hydrocyclone separator design

1. Construction parameters: Including cone diameter and height, inlet diameter, overflow line diameter, and cone angle, the discharge line diameter and the installation manner of overflow line
2. The operation parameter: Inlet pressure, back pressure of overflow line
3. Drilling mud property: Content of solid particles, solid percentage, viscosity, solid density, etc.


Desander and Desilter cone drawing resource

Desanders shall draw suction from the compartment immediately downstream from the degasser compartment. Desilters and mud cleaners shall draw from the next compartment, and centrifuges from next compartment.

If a centrifuge or centrifuges are used on the active system, the centrifuges process fluid from the piping between the pump and the input manifold for this equipment shall be as short and straight as possible. There should be no ells, reducers, or swages within three pipe diameters of the flange connecting the piping to the manifold.


Procedure for design of mud cleaners

As noted in previous clauses, mud cleaner hydrocyclone installation follows the rules for desanders. Mud cleaners shall be used when commercial weighting agents are added to the drilling fluid. Screens on the main shale shakers.

Mud cleaners remove additional drilled solids even after the fluid has been processed by API 200 plugged desilter cones indicate drilling fluid bypassing shale shaker screens. Screen throughput from mud cleaners shall be returned to a well-agitated location in the drilling fluid well.

So many solids control manufacturers all over the world. We treat Derrick, NOV Brandt, Mi-Swaco as top one. And they do make wonderful products. However, the price and mainteniance cost is sky high. That make more and more user toward to other qualified, API certified manufacturer. Then GN Solids Control become rather popular all over the world.
