Solid control equipment desilter usage introduction

Desilter used in solids control system is the 3rd phase equipment. Desilter is set after desander and prior to decanter centrifuge. The flow rate of desilter separator is decided by cones number. Usually, we utilize 4″ cone for desilter.

desilter

Each 4″ cone holds capacity 12~15m³/h. To achieve desilter separation there should be centrifugal pump as cone feeding pump. Under pump transfer power, there will be sufficient pressure pull drilling fluid swirl in cones body. Then solids will be separated out by centrifugal force. Theoretically, desilter will get rid of solids sized over 15 microns.

There are thousands of manufacturer all over the globe manufacture solids control equipment. Desilter is one small part of such equipment.

Normaly working flow of hydrocyclone desander

A hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers and degassers, but before the desilters or mud cleaners.

A volume of mud is pumped into the wide upper section of the hydrocylone at an angle roughly tangent to its circumference. As the mud flows around and gradually down the inside of the cone shape, solids are separated from the liquid by centrifugal forces.
Desander

The solids continue around and down until they exit the bottom of the hydrocyclone (along with small amounts of liquid) and are discarded. The cleaner and lighter density liquid mud travels up through a vortex in the center of the hydrocyclone, exits through piping at the top of the hydrocyclone and is then routed to the mud tanks and the next mud-cleaning device, usually a desilter.

Various size desander and desilter cones are functionally identical, with the size of the cone determining the size of particles the device removes from the mud system.

What functions of hydrocyclone in solid control system

Hydrocyclones are simple mechanical devices, with out moving parts, designed to speed up the settling process. Feed pressure is transformed into centrifugal force inside the cyclone or cone to accelerate particle settling in accordance with Stoke’s Law #1. In essence, a cyclone is a miniature settling pit which alloys very rapid settling of solids under controlled conditions.

hydrocyclone

Hydrocyclones have become important in solid control systems because of their ability to efficiently remove particles smaller than the finest mesh screens. They are also uncomplicated devices, which make them easy to use and maintain.

Design features of cyclones units vary widely according to the size. The cyclones are made of composite materials and hold up to wear quite well. The size of cyclones in use varies from 12” down to 2”. The measurement refers to the inside diameter of the largest, cylinders section of the cyclone. In general, but not always, the larger the cone, the larger the cut point and the greater the thru put. Refer to the figures below:

Hydrocyclones are another important line of defense in the battle against the removal of solids from your drilling fluid.

The double deck desilter unit used for drilling water site

The double deck shaker is usually a dual-function unit which can be used both as shale shaker and mud cleaner, the bottom shaker is taken as shale shaker to separate big solids, the best shaker is acted as desilter flow shaker. The double deck shaker with desilter is widely applied for the well drilling field.

Double deck shaker with “desilter cone and founfation small tank

Fluids will firstly be pumped onto the bottom shaker, the shaker screen is small API number to separate the lar123ge particle from the fluid. Secondly, DC high effective centrifuge pump will transfer the fluid to desilter cone for second step process.

The top deck will handle the fluids from apex of de sander cone.. But the feeding type is very simple way in which can save the working space. Higher mesh shaker screen is applied on the shaker than de sander shaker. It is effective for the 250GMP and 350GPM capacity.

Besides abobve, the small unit includes a tank which is a base of the desilter and mixing material. To be as a professional manufacturer of mud equipment. DC Machiney can design all types mud system unit used for different areas, such as, oil& gas drilling, HDD, CBM, pilling project and ect.

 

Semi-finished Mud tank and desilter in DC Workshop

DC Solid control almost the production of the two mud tanks, mud hopper and desander equipment. The specification design equipment manufactured an American drilling company who are our new clients in OTC exhibition.

The requirements of the mud tank:

A Mud Tank is a container made from steel plate and steel tube with an open top for storing drilling fluids on a drilling rig. The small mud tank dimension, material and paint color all have specification request.

The requirements of the mud desilter:

The desilter should has should be input pipeline, output line, bottom shaker, base frame, etc. Also there maybe without bottom shaker according to user’s demand. The technique specs should be from user’s requirement on treating capacity, actual operation environment, etc. Usually the desilter cone diameter is 4″. Presently, DC desilter mainly use PU material cones, and clamp type one. Furthermore, there can be desilter cone with bottom shale shaker or not.

desilter

Except oilfield desilter and tanks, DC Solid control can also supply oilfield drilling shale shaker,oilfield drilling decanter centrifuge, oilfield drilling mud desander, oilfield drilling mud cleaner, shaker screens and the complete set of various solids control systems.

 

Old-fashioned desander and desilter delivery from DC Solid control

Desander and desilter is widely used in mud cleaning system. Following the progress of the time and high requirements of users. The desander and desilter all make greats progress. But recent days, DC Solid control company got an order of 6 sets old-fashioned desander and desilter used for HDD industry.

Desander is installed on top of the mud tank following shale shaker and vacuum degasser, but before the desilter. Desilter is installed on top of the mud tank following Desander. They also can be installed completely: in this case, they are installed on one deck shaker and called mud cleaner or mud conditioner.

desander desilter

Desander removes the abrasive solids from drilling mud which cannot be removed by shale shakers. Normally the solids diameter for desander to be separated would be 45~74μm, and 15~44μm for desilter.

Both Desilters and Desanders are available in a large range of configurations including stand alone, over a shaker as a mud cleaner or packaged with a supply pump as a mobile desilting unit. Please contact DC Solid control office to discuss applications and appropriate technical specifications.

 

DC Solid control desander and desilter working process

Desilters and Desanders are used to process large volumes of drilling fluid to remove abrasive sands and silts that shale shakers cannot remove.

DC Solid control Desilting and Desanding hydrocyclones are made from high density abrasion resistant polyurethane. The unique internal manifold design minimises the back pressure on the hydrocyclones maximising the solids removal. Fine tuning is achieved through adjustable orifice openings at the discharge point on the cone.

DESANDERS

Desanders are what larger diameter hydro-cyclones are typically referred as, and will be the next step in solids removal after an initial scalping shaker pass. Desanders are capable of handling large flow rates, up to 500 gpm per cone, but do not offer as fine of a cut. The underflow will be recirculated over a shaker and processed again while the overflow will be free to move on to the next stage, typically a desilter.

DESILTERS

Desilters are what smaller diameter hydrocyclones are typically referred to as, and will generally be used directly after a desander. Occasionally desanders will not be necessary and the desilter will operate immediately after the scalping pass. While desilting cones can achieve a finer cut, down to 20 micron, than desander cones they cannot process at as high of a rate per cone and are headered together in order to meet the desired throughput. The Underflow will be recirculated over a shaker and processed again while the overflow will be free to move on to the next stage, whether it’s a centrifuge, chemical treatment, or a finished product.

Testing desander unit used for piling field in DC Machinery workshop

Desander is an common equipment of piling field which mainly separate out the 45-75um solid phase. Last week, the desander unit manufactured for Singapore clients tested in DC machinery workshop.

Structure of piling desander
