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.

WASTE OIL SLUDGE TEATMENT PLANT

Oil sludge is the by-product when producing oil, mixed with water, oil, and solid sediment, which is the dangerous waste but has high recycling value. With the increasingly tense supply of oil resources, many countries are doing researches in oil sludge recycling technology. The pyrolysis technology is drawing wide attention of researchers all over the world with its advantages of disposal thoroughly and high energy recycling. The proper oil sludge treatment is essential since these waste materials are hazardous to human and environment.

In oilfield operations oily sludges are produced as sediments in tanks and apparatus, as well as from oil spills (e.g. in the course of maintenance / repair work, or due to pipeline leaks). Those sludges, in their original form, can have extremely high solids contents at moderate to high oil contents. However, at the time when the sludges from different sources are combined and prepared for treatment, the oil / water / solids ratios are such, that treatment with normal oil sludge processing equipment is easily possible. Very often oilfield sludges are collected in lagoons and withdrawn from there for processing, rather than being processed directly downstream of the source / collection point.

The differing origins and compositions of waste oil mean that its water, oil and solids content can vary considerably. A water content in the order of 40-80% by volume, approximately 10-50% by volume oil phase with rather high viscosity, and a high solids content (in the order of 10-40% by volume) with potentially very large particle sizes, as well as potential content of significant amounts of other debris often characterize this product.

Compared to many other waste oil applications, the product properties oil field sludges require special attention be given to the mechanical pre-treatment of the sludges prior to processing. And because the recovered oil is usually not refined on-site, but rather added to the crude oil stream before it is sent to refining, the oil quality is normally sufficient using 3-phase decanter technology, which means these systems can typically be designed with one single 3-phase separation step.

Wide Applications of GN Dewatering Unit

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:

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.
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.

Waste Mangement System Design

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.
