As two indispensable equipments in the solid control system of oil & gas drilling, desilter and desander?are responsible for separating the small solids in the drilling fluids which has been treated by the shale shaker & desilter,The desander takes care of the solid with diameter 45~74μm, and 15~44μm for desilter.

Normally desanders are mounted on the top of the first mud tank together with shale shakers & vacuum degassers, while desilters are mounted together with centrifuges. Sometimes to save the top area of the mud tank, desander & desilter are combined together to work as high efficient mud cleaner.

How to Choose and Design Desilter System,you must care to select Desanders & desilters, high pressure flow?pipes & a small shale shaer at the bottom. For How to Choose and Design Desilter System, only one ways of above is not enough,you also need record the releated Parameter。

while for high efficient it would need two motors. There would equiped two 10″ or 12″ diameter?iron hydrocyclones for desilter just as the solids need to be separated is relatively big, and include some sands in the mud. While for desilters, it would equiped 6 to 12 pcs 4″ diameter hydrocyclones?which are?made of wear resist plastic.

Working Principle of the hydrocyclones.

Hydrocyclone Working Principle – GN,For the work principle of hydrocyclones, it works like this. First the drilling fluids are?sucked up to 0.25Mpa ~ 0.4Mpa by sand pump, and enter into the cones through the side inlet which is?normally only 2-1/2″ diameter. The fluids then flow spirally inside of the cone. Effected by the centrifugal force, the heavy solids in the fluids would be throwed towards the?inner wall of the cones,?go down to the bottem, and discharge through the sand discharge port, while the light fluids would go up and discharge through the upper oulet. The diameter of the bottom discharge port is adjustable, and with a cover of hydrocyclone.

As an quick-wear part of VARIETY OF DRILLING MUD SYSTEM, the lifetime of hydrocyclones is not so long as other parts. So it is neccessary to check their working condition, and replace them with new ones. As a whole set of the hydrocyclone, clamps & flang are also replaced together with the hydrocyclones.

GN america company ’s USA desander are combined by 10 “or 12” hydro-cyclones and pipes, operation and maintenance much easier. The use resistant special polyurethane of abrasion that is corrosion-resistant and anti-clean and has a long life.

Put the materials in machine along the tangent line of feed input, the transition is smooth and agrees to improve separation efficiency. The route of the separation size is large. The lower River hole of the hydro cyclone unloads the sand particles, while the particles are quickly unloaded an umbrella and the “wet bottom”, unloaded, and reduces the likelihood of the lower River hole block.

The balanced input structure forms the hydro cyclone distribution fairer and more stable work. The lower River hole can be adjusted to control the treatment capacity, to bring together the various requirements. According to the requirements of clients of treatment capacity, the desander can be made by some groups of the hydro cyclone.

Used desander  of the Mission of Magnum with a cetain discharge to provide capacity and pressure to the desander, the Desilter and mud pump. The centrifugal sand pump through more than 10 years developed  site  applications and enhancements by the surplus of the company, is in the domestic advanced level, either in the technical performance or the seal life and reached the same level as the other similar products away.

The desander has two types of drive, electromotion-and belt drive. New products can be designed according to customers’special requirements and will be made available.

Polymer Muds are special types oflow solids mud which contain synthetic materials, polymers, designedto control viscosity and fluid loss.Polymers are very expensive and1.11often difficult to screen when ahigh viscosity fluid is used.Calcium Treated Muds are special water-base muds, usually weighted,which have lime or gypsum added.Calcium Treated Muds are normallyused to prevent shale type formations from swelling or sloughing –problems which could lead to stuck pipe or a ruined hole. Since the desander is a very special parts and you want to buy and using.For visiting www.gnsoldisamerica.com click here.

Dredging Material Treatment is always a big problem for local governments, especially for De-watering the material.

GN Solids Control can supply One Stop, Turnkey Solution for Dredging Material Treatment.

Last week, GN 1000 GPM dredging slurry separation system was delivered to work site for customer’s project starting celebration. It is the first unit standard configuration system for dredging slurry separation which showed that GN has made herself getting into a further level for river and lake sludge cleaning up.

Main Equipments for 1000GPM Dredging Slurry Separation System,
1. GNZS703 Shale shaker – 2 Units
2. GNZJ703-2S De-sander – 1 Unit
3. GNSB6x5-13 Sand Pump – 2 Units
4. Mud tank and accessories

Working Procedure,
The Dredging Slurry firstly go through the shale shakers, in order to remove the solids with more than 100 um. The slurry after the Shale Shaker Treatment would go through the De-Sander, in order to remove the the solids between 45~70 um. There are independent mud tanks under the shale shaker and De-sander, for collecting the liquid separately passing from the shale shaker and De-sander.

The two sand pumps are used for feeding material into the Shake Shaker and De-sander Separately.

GN also develops Decanter Centrifuge for removing fine solids (up to 5um) from liquid, and removing all the Solids from Liquid, with Polymer Dosing System.

GN Solids Control is one of the largest solid control and waste management companies which specializes in manufacturing the related equipment, such as shale shaker, desander, desilter, mud cleaner, vacuum degasser, mud gas separator, decanter centrifuge, agitator, centrifugal pump, cutting dryer, screw pump, shear pump, mud gun and so on. After 10 years development, GN has promoted its products to over 60 countries and now it also established two overseas subsidiaries, US and Russia.

Recently we have been forced our main work force on pushing our Decant Centrifuge into the North America Market. So far we have got many good feed back from different end users in both The U.S and Canada. Our decant centrifuge system works in many different environment, . They can be working at super hot desert environment. The VFD control system is provided by SIEMENS or ABB. All the bearings applied in the centrifuge are from SFK premium bearing which can guarantee longer operation life and more reliable operation. All the motors and control panels are explosive proof and certified to work in zone 1 and zone 2 hazardous area. The 553 decanter centrifuge will become the star products for processing large volume of liquid and solid separation job. More and more customers are showing great interest in it. Also for many different industries, they have also chosen our decant centrifuge to be their first option of solids separation. Now GN can not only manufacture its traditional 363 centrifuge with 14 inch bowl, but it can also make larger bowl size, GNLW553, whose bowl size is 22 inch. This equipment can be applied in the processing the water based mud, in the oil based mud system, in dewatering and in recovering barite. There are also some great features for this equipment: it is VFD controlled and can offer the operators a variety of solutions for the changing field operation situations.

That’s the basic introduction of the large bowl decanter centrifuge 553. Hopefully it will be useful to you. We will try our best to assist your business to be successful. Welcome to visit www.gnsolidsamerica.com and please send your inquiries to USA@gnsolidscontrol.com
