GN oil drilling zero disposal solutions

GN solid control zero disposal solutions drilling system is mainly in order to meet the demand of environmental protection and develop and sludge decrement disposal requirements through innovative closed-loop processing system.
1, the process is introduced
Drilling waste liquid of solid-liquid separation using coherent processing mode, coagulant and flocculant treatment mainly rely on the automatic traffic monitoring and control system to join, dosage, easy control, waste liquid and the treatment of mixed mode mainly adopts mixer, drilling liquid coagulation gel breaking in waste liquid of static mixer screw pump inlet pulp inlet branch tee complete mixed filling.
2, the principle of design
: 1) the feasibility on the market at present existing backward equipment and technology upgrade, improve the process control and operation convenience;
2) : advanced processing technology and equipment adopted mature and stable technology and equipment, improve the work efficiency, energy conservation and emissions reduction;
3) reliability: design process has successfully applied in other similar projects, the practice proved reliable performance;
4) the economy: on the premise of ensuring effect, in line with the investment saving effect, the best idea;

4) auxiliary equipment: pump, conveyor and so on.

Decanter Centrifuge use in mud separation

Decanter centrifuge use in solid separation for drilling fluid after desilter, which done by the 4 inch hydrocyclone  The drilling mud at this stage may contain solids between 2 to 5 micron and in some case, it contain the barite, the reusable additive.  Decanter centrifuge ‘s purpose is separate this fine solids and recover the barite to achieve purification of drilling mud so it can be sent it back to rig and use it for drilling many times over. 

The basic concept of decanter centrifuge is use G-force rotate the bowl “spinning” to create the weight difference so the solids is separate from the mud.  During the high speed spinning in G-force, the solids move in one direction while the mud moves to opposite direction to achieve the separation and two exits below the decanter centrifuge will be one for exit of solid while the other one is for the mud that is done separation. The centrifuge generate centrifugal force amount to 400g~3000g acceleration, only need a short time accomplish the separation process

Such process is accomplish by feeding the drilling mud after the separation of desilter and feed the mud into the decanter centrifuge. Decanter centrifuge mainly use for recovering the barite and get rid of small solids in the mud for reduce the solids in the drilling mud.  This step to make sure the function of drilling mud back to near as new as possible, which the drilling rig bit need for continues drilling.  

Drilling rig need this cleaning step is purposely maintains the cost of the drilling. The maintains of drilling cost is by product.  The main reason is if solids separation is not done properly, the density of small solids will raise and that will seriously affect the drilling bit which will cost raise temperature in the mud and cost damage of the drilling bit and many other types of machinery to over worked and lead to structure damage of the drill rig. 

GN Solids America LLC have decanter centrifuge in many bowl sizes

GN Solids America LLC is the USA subsidiary company of GN Solids Control LTD, which is located in near Beijing, China.  Since 2007, GN Solids Control has been a major manufacture and exporter on drill cutting solids control machinery.  Through years of good feedbacks and prompt service request responses, GN Solids America has been export over sixty countries around the world.  We manufacture the full time of solids control machinery like shale shaker, desander, desilter, mud cleaner, vacuum degasser, mud gas separator, decantercentrifuge, agitator, centrifugal pump, cutting dryer, screw pump, shear pump, mud gun and custom mud recycling system that contain machinery on the list. 

The decanter centrifuge that GN Solids America LLC manufacture is one of the core machinery and we off various size of bowl of it.  The model GNLW363 centrifuge with 14 inch bowl which is selling the most but GN Solids America LLC also make larger bowl size, GNLW453 and GNLW553, whose bowl size are 18 inch and 22 inch. These two equipment can both be applied in the processing the water based drilling mud, in the oil based drilling mud, in dewatering and in recovering barite.

The decanter centrifuge we manufacture offer both fixed speed and VFD controlled option.   It offer the operators a variety of rotate speed for the various field operations. The duplex stainless bowl are made from centrifugal casting wit consist balance and corrosion resistance. All the screw conveyors’ surface is protected by tungsten carbide tiles which can protect the entire length of the screw conveyor. The decanter centrifuge can operate in extreme weather condition  as cold as north pole to the hot as middle east dessert. The VFD control system parts is provided by SIEMENS or ABB. All the bears applied in the centrifuge are from SFK premium bearing which can guarantee longer operation life and reliable operation. The control panel, main motor and gearbox motor are explosion proof of zone 1 and zone 2.  The decanter centrifuge can tailor made to comply local region of drilling operation. 

We GN Solids America LLC keeps consist in-stock machinery and replacement parts at all time and offer very aggressive price which surely keep your operation budget in consist base.
