decanter centrifuge

GN solid control is the most the most cutting-edge technology, solid control and drilling waste management equipment manufacturer in China, which produces the mud centrifuge has been the largest oil giant enterprises of domestic and international several full approval. In the just-concluded 2016 CIPPE oil show, crown can solids control the display of the centrifuge series, series of mm small convertible centrifuge from 220 to 550 mm of big drum centrifuge, lined up at the scene of the exhibition, has made a lot of audience attention and end users.

Especially GNLW36 centrifuge model, both in the appearance of the old version and the new design was shown in the CIPPE 2016 booths, so what is the difference between GNLW363 decanter centrifuge is a new generation?The following simple statements.
1, the first generation of GNLW363, originally designed for 360 mm horizontal spiral sedimentation centrifuge, one will have two motor is a main auxiliary, respectively installed on both ends of the centrifuge.Though, is the highest level of materials, the design concept of the centrifuge is basically the same with other domestic counterparts of the old.
2, the second generation GNLW363B, more international, with the crown to solid control has been the product sales in many countries and regions of the world, as well as the champions league to the product design is becoming more and more internationalized, GNLW363B horizontal screw centrifuge before the two motor position has a into one end is at each end of the two, mainly is to increase the operator have more space and centrifuges operating characteristics of easy to maintain, stable operation.

3, the third generation GNLW363C sedimentation centrifuge, in addition to the basic drilling mud solid control can also be used for oilfield waste pulp processing, it is similar to GNLW363B, two motor on one side.But on the other details GNLW363C also has a better update on structure, structure, based on the B version upgrade C version of the centrifuge and been used in many fields.Such as sludge separation, flocculation and dewatering unit, waste pulp processing, etc., with the user feedback, after upgrade C version of the centrifuge in use process compared to B version, processing capacity increased by 50%, continuity of operations, rugged conditions objection to adapt.
4, the fourth generation of GNLW363D, the inside of the design and GNLW363C are similar, but the outlook is completely different, because the structure is higher than C version is more compact, the stability, its total weight is reduced by 30%, is advantageous for the urgent needs air

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, decanter centrifuge, 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. 

GN is now marching into the industry decanter centrifuges, which means more and more problems can be solved. Not only oil gas, environmental etc….

Dewatering unit is also called flocculation unit, it means to flocculate the extra fine particles with the help of 2 or 3 chemicals into larger ones for further separation by the decanter centrifuge. In many regions and countries in the world, only a solid control system and a drilling waste management system are not enough to be a complete zero discharge closed loop without the help of the dewatering unit.

GN Dewatering Unit

In this case, the dewatering unit is used for following applications:

  1. Alongside the drilling rig systems, the dewatering unit is used for separating out the extra particles from the solids control system when the drilling mud in the solids control system has been used for several times and there are lot of extra fine particles smaller than 2 microns.
  2. In a mud plant or mud station especially for the dewatering project. In this case, the drilling mud is storage in some tanks waiting for being treated by a dewatering unit, but this place is not alongside the rig.

There are still some other applications the dewatering units could serve:

Oil sludge project, in such project, the condition of mud is similar as above mentioned mud for the dewatering units, the sludge is of high viscosity and the solids particles are very small. So the operators need to add some chemicals to merge the particles into larger ones. This is a jobsite working video of GN mud mixing system in this case.

In previous projects, GN dewatering units are also suitable for mud tank cleaning projects, with some auxiliary equipment and devices.

In some countries, when the environment standard is high, some clients even use dewatering unit for TBM project.

GN has some standard configuration of dewatering units, mostly ,the dewatering unit is installed in a 20 ft container and could be transported as a 20 ft container. And it is designed for 2 chemicals. According to clients’ customized request, there are more designs available.

 

Firstly THE WASTE

Well like everything you want to manage, you should know it. So basically where is it from, what is it consist of, the charactor densitiy, viscosity, solids content, size distribution.

If you do not know, do not worry, there must be a lot of labs ready to help you.

THE RESULT

Then what kind of result you want?

Any standard you need to comply?

Or based on the waste analysis you have, and find what you do not need, or what you need, then decide what to be separated out. And how?

The Waste Management Equipment

There are a lot of equipment based on different material, different purpose, different application. While lots of them have same / similar principle. For drilling related waste and environmental projects, below equipment is the basic ones

Drying shaker, like the other shale shakers, but have higher G force, so can separate higher viscosy parts, or the fluids wanted to stay with solids.

Cuttings dryer, it is working like a centrifuge, vertical, with screens. so the liquids can be able to sepated in the solids looks like dry parts.

Well at the same time, some people may also consider solids control equipment as part of the waste management equipment, so we also count on shaker, mud cleaner, centrifuge etc.

Decanter centrifuge, the centrifuge is almost everywhere, even decanter, most of them seems like same but acturally different, with different specifications.

Dewatering unit, chemicals is helpful on all these progress.
