In traditional mind, the solids control and waste management is the world occupied by USA and European companies, especially in American own territory, there’s seldom other brands from outside USA. But GN Solids Control, as the first API certified solids control company in China and also the first USA based China solids control company who has a branch company and warehouse in Houston.

Not long ago, GN after sale service team came back from Transocean Offshore Rig jobsite in America, bring back valuable feedback and data. On this jobsite, they are using GN’s decanter centrifuge.This decanter centrifuge GNLW363-VFD, with max rotating speed 3900 RPM. This centrifuge is ideal solution for such application, besides the traditional application as solids control and waste management. Because of the VFD control system, this centrifuge’s speed ranges from 0 to 3200, could be used for separating the large and heavy particles and ultra fine small particles.

The end user has 2 centrifuges of similar treating capacity on this working jobsite. One is from GN Solids Control ,the other is from Baker Hudges. Normally, the run one of the 2 centrifuges and the other is used like backup centrifuge. In most cases, the capacity of one set is enough. When the treating capacity requested is larger, they run both of them together. The ender user was surprised that Chinese brand centrifuge could be equivalent as the Baker Hudges one. Before using GN’s centrifuge, they hesitated for a while and finally decided to trust and try. GN didn’t fail them.

They got to know GN’s quality, but there is one thing they didn’t know, that also Baker Hudges is GN’s client and end user of GN decanter centrifuge. Now there are four sets of GN Waste Management Systems running at Nabor’s jobsite, where Baker Hudges is providing service.

It is quite surprised to know the feedback that the chemicals works more than we expected. It is now well known that with proper chemicals, especially the oilly sluge, the OBM waste cuttings, can be well separated. Then the mechanical machine can just assisting the whole process to make it better way.

With oil waste, as I am sure you know, there is no “one size fits all’ but we have experienced some very effective processes in our time. Let me share a little of that experience with you by walking you through one process we have seen work very effectively in the past:

Pump the waste from your storage tank to the centrifuge input feed

Just before it enters the feed use a static inline mixer to mix the chemical with the sludge you can use a range of chemicals to aid the separation process (this could be anything from demulsifier to polymer or SAS Microemulsion products)

The mixture is then fed through the centrifuge.

The solids separate from the liquid and fall out the bottom of the centrifuge.

The liquid, which will contain oil, water and some chemical is then pumped to a settling tank.

Then as all know, before dumping the waste to the environment, solidification, thermal desorption, or biodegradation; thermal desorption is by heating, biodegradation is using germs, solidification is the most convinient and easy to be widely used. Yes, it is with chemicals, absorber, cement, other fluid chemicals are needed in this process. With proper mixing, the toxy parts are stable, then can be dumped to the environment.

The right chemical, in proper way.

Though chemicals is helping us to solve the final problem, separate the drill cuttings & fluids, have to be used properly. Like our first origin concern, it might hurt, people, and environment.

Micro emulsions gift a spread of recent opportunities for the waste management industry, and area unit dynamical the business in five elementary ways: one. Gap new markets for waste treatment firms Waste treatment firms have developed processes for treating specific styles of waste. Once waste treatment firms stumble upon new styles of waste that will need a special variety of treatment, existing systems could struggle. one amongst the distinctive characteristics of micro emulsions is that they will be effective on a good vary of oil contaminated waste sorts, together with however not restricted to, plant waste, oil base muds, flow back waste, drill cuttings, marplot waste and fighter aircraft waste. this suggests that having micro emulsions as a part of the method can enable waste treatment firms to expand the kinds of waste they will treat, while not having to create important changes in their method or invest in new instrumentality.;

2.Treatment is moving upstream to eliminate issues downstream Waste treatment firms area unit asked to treat a good vary of waste sorts to progressively strict standards. each waste stream is completely different and will need a special methodology of treatment. This presents important challenges. one amongst the challenge is that several treatment strategies turn out residual waste that need any treatment. One advantage of microemulsions is that once used early within the treatment method they considerably scale back the quantity of residual waste streams. the most objective of treating oilcontaminated waste is to separate the oil, solids and water phases. Microemulsions area unit extraordinarily effective at separating these 3 parts. Waste treatment firms World Health Organization use microemulsions early within the treatment method area unit able to improve process efficiencies throughout their operations. leading to a movement towards treating “virgin” waste as so much up-stream as attainable.

3.Microemulsions area unit stimulating the event of recent business models Microemulsions modify waste treatment firms to recover a lot of prime quality hydrocarbons than ever before. Microemulsions area unit facultative some waste treatment firms to operate a lot of like drilling firms, by permitting them to recover giant volumes of oil from oilcontaminated sludges and slops. For alternative waste treatment firms, microemulsions modify them offer a lot of worth for his or her shoppers by convalescent a lot of prime quality oil on their behalf. the extra revenue from exaggerated oil recovery will enable waste treatment firms to supply a lower value treatment service. this may facilitate waste treatment firms World Health Organization use microemulsions win a lot of business.

4. Heat treatment can become progressively rare several treatment firms use energy intensive methodes like heat or thermal treatment as a core element of their process. Heating a one hundred,000 gallon tank of oil-contaminated waste to 70-80C, and maintaining that temperature for days, generally weeks, is costly. In several cases microemulsions area unit able to deliver an efficient split while not exploitation heat. This dramatically reduces treatment prices and treatment times, maximizing outturn volume. 5. Polymers are going to be dose pressure Polymers are a mainstay of the waste treatment business for many years. Polymers were originally used for water treatment, and therefore the business created the natural extension to use polymers to the treatment of liquid oilcontaminated wasteHowever the effectiveness of polymers decreases because the oil content of a waste will increase. Polymers work by “grabbing” the oil and solids and protection them along, leading to a 2-phase separation of fresh water and oily sludge – one thing extraordinarily troublesome to treat. this is often why polymers ought to be used just for de-watering, however not for removing oil from solids. Microemulsions work by “releasing” the oil from the solids, and once separated, the relative weights of oil and water end in a natural separation. wherever polymers deliver a 2-phase separation, deed a lot of work to be done, microemulsions deliver a 3-phase separation, achieving a a lot of complete treatment method in one pass. The business is quickly realizing that microemulsions area unit a lot of applicable for the treatment of oil-contaminated sludges, resulting in the speedy adoption of the technology. This industry-wide shift is inflicting operators to re-think once and wherever to use polymers in their treatment method;

Zero discharge drilling mud system is also called no-pit drilling mud system, traditional drilling system is to open an hole beside the drilling rig and have the waste drilling cuttings storage there and ship them to the drilling waste management facility or set up drilling cuttings treatment system beside the pit. No pit drilling( or called online drilling) required the drilling waste management system set up beside the drilling rig without open/ drill a hole. It can less the hazardous damage to the earth and underground water, it is strongly recommend in China now for all kinds of drilling after the new environmental protection laws is issued this year.

Not only for oily drill cuttings treatment, but also the water based drill cuttings need to be treated after drilling. The main equipments used for water based mud drilling cuttings treatment is as below:

1 Hi-G dryer shaker

GNZS594HGE-LD high G drying shaker with hopper feeder is the most popular dryer for water based mud.

2 Vertical cuttings dryer

GNCD930C vertical cuttings dryer can be applied for both water based drilling cuttings and oil based drilling cuttings. You can use it for different projects by only purchasing one unit vertical cutting dryer. At the beginning of the drilling, water based mud is utilized, when the drilling depth is increased, oil based mud is applied, you do not need to change your drilling waste management equipments, it can save your drilling cost.

3 Decanter centrifuge

With high G force decanter centrifuge, the separation point is about 2~5 microns, if you would like to separate the solids under 5 microns, you need to add polymer unit-GN1500 dewatering unit which is put inside the 20ft standard container for convenient shipment.

After treated by GN high speed decanter centrifuge with 3200rpm, the waste solids is transferred to TDU for further treatment.

GN is a young company with energy, with passion. Every year, we made some improvments, will never paving at the same places for a decade. With more and more focusing on waste management & environmental protection, this year to OTC, our main exhibiting product became the verticle cuttings dryer & high speed decanter centrifuge.

1) GNCD930D Series Vertical Cuttings Dryer.

GN Solids Control is one of the only two companies in the OTC 2015 who displayed the vertical cuttings dryers. Unlike our competitors vertical cuttings dryers, GN dryers is with higher speed up to 1200RPM with G force up to 750G. This gives it more ability to separate the oil on the cuttings, especially of WBM, it works well for the critical WBM.

GN has already done successful drilling cuttings management projects for Shell, Baker Huges, CNPC and many more leaders in the industry.

As we always keep telling, the statege, finally works well. When the flowers blooms outside the wall, people inside smells. Well, after big players comes to us, and like a healthy cycle, business is on the right track.

2) High Speed GNLW363CG-VFD Decanter Centrifuges.

GN 363 series Decanter Centrifuges is the most popular size decanter centrifuge for drilling mud treatment. GN built over 100 this size of decanter centrifuges in 2014. This type and size of decanter centrifuge is popular for solids control, dewatering ,waste management, sludge treatment.

After the beautiful queen, here comes the old king. Not only keep developing new business, all GN old products are keeping optimized on details. Like the:

3) Mud Cleaner 3in1 GNZS594E-2S12N

After optimized the whole structure, now the mud cleaner can be easily disassembled to two main parts, the cyclone frame, and the underflow shaker. Not like the old designs, need keep matching all the four bolts. If sometimes needed to be disassembled, the tragedy comes. If not something well accurate manufactured, well maintained, days passed to assemble it.

The facts that needs to consider for choosing shale shaker
The capacity of treating fluid (GPM)
The type of fluid, the ratio of the mass density, the speed of flow and temperature that needs to be treating.
Any fluid contains that might include salt and/or acid of materials (Confirm to use 304# stainless steel or 316L stainless steel)
Size of the solids material that leads choosing screen.
The sums of meshes (API)
Where to install the shale shaker in oil field

The first -time set-up of the shale shaker

When first set-up the shale shaker, it needs keep put the shaker on a leveled surface.
The shock-resist rubber materialsneed be installed between the box and bracket.
Remove the shipping brace like bolt and lug, because the base and screen box are connected by springs, so when ship, the above part of the equipment is secured by the shipping brace.
Remove all the shipping braces before operate the shale shaker.
The motor cables connected the vibration motors on the shale shaker always damaged during severe vibration.Cable coversare provide and need to install with cables when connect control panel and the motors
When stop using the shale shaker, the shale shaker screen should always be washed by clean water.  It also needs to use diesel fuel to clean the screen first, and then water when treating oil-base fluid.

The installation of shale shaker screen

Install the wedge blocks at the two sides at the same time.

Make sure the wedge blocks are firmly installed before turn on the shale shaker.
Do the test-run after the installation of shaker screen to ensure installation is done corrected .   If there is any unusual noise of poor contact, stop immediately and re-check the installation of shaker screen.
