3 phase decanter centrifuge is widely used for crude oil sludge separation to discharge the dry solids and recovery oil as more as possible, at the meantime, the water is recycled for reuse. Before feeding, we need heating the original material to be liquidable.
There are 2 situations:
1 The oil sludge is from oil storage tank bottom or mut pit bottom, most of the sludge is fine solids, by this situation, 3 phase decanter centrifuge could be an option.
2 The oil sludge is from drilling site, most of them are drilling cuttings, GNCD930 vertical cuttings dryer works this way. After separated by GN vertical cuttings dryer, the oil content on the cuttings will be down to less than 5%, in some countries, the solids can be landfilling, the recoverded oil with water, fine solids can be separated by 3-phase decanter centrifuge or GNLW363VFD 2 phase decanter centrifuge to separate the fine solids and get clean oil.  
We have both the vertical cuttings dryer and 2 phase decanter centrifuge stocking in Houston for immediate shipment and customer’s inspection and rental service. Pls contact our sales team in Houston at 713 320 3868/713 878 0880 to arrange for a visit.
Working principal of 3 phase decanter centrifuge:
3 phase decanter centrifuge can separate 3-phase: solids phase, light liquid phase, heavy fluids phase through the process below: With the centrifugal G force, the heavies phase-solids phase is drived by the screw conveyor to small end and discharged from solids discharge port, the solids is dry enough to be shipped by truck. The 2 different density fluids will flow to big end and discharged from different effluent port-heavy fluids port and light fluids port. So the different 3 phase are separated.
GN produced 2 phase separation decanter centrifuge is widely used for drilling fluids treatment for solids control system and drilling waste management system.

GN brand high speed decanter centrifuge has been used for waste water reclamation in the oil & gas field. The purpose is to help you use less water or recycle more water to save you money, and work in an environment responsible manner.
Oilfield waste water may come from the fluids stream below:
1 onshore drilling
2 offshore drilling
3 oil tank bottom/pit
4 drilling waste management system/facility
Decanter centrifuge act as an important role but not the final in the process of water recycling. It is used to separate the clay and silts from the fluids and dry the solids for disposal. GNLW363CG & CG-VFD decanter centrifuge and GNLW453-CFD, GNLW553-VFD centrifuge can be used for such application.GN have all these centrifuges models available in GN SOLIDS America warehouse located at Houston for sale and rent, pls contact GN sales for an appointment in our warehouse.
GN decanter centrifuge can be applied not only for oil & gas field, but also industry waste water, like dredging slurry separation, pond slurry separation, mining slurry separation, TBM, diamond core drilling waste water, etc. But before feeding the fluids to the centrifuge, it is necessary to confirm the big solids/rock/stone/tree has been removed.
Features of GN decanter centrifuges:
1 Screw is protected by tungsten carbide tiles for longer working time, and repairable and replaceable, thickness is over 4mm
2 mud distribution port is protected by ceremic insert of abrasion
3 solids discharge port is protected by tungsten carbide ring and replaceable
4 Scraper on the centrifuge bowl end & side and Solids blocking cover to prevent it from solids accumulation outside the bowl
5 Bowl Material SS2205 made from centrifugal casting for better balance and longer life
6 High speed, high G force and variable speed can be applied for high gravity drilling mud, low gravity and barite recovery

Drilling waste are consist of drilling cuttings, waste water produced by drilling and oil storage, oily sludge, tank bottom waste, etc. GN vertical G dryer system can be used for all these types of drilling waste with our customized design. We have standard equipments just put them in different layout and use different speed( G force) to get the required result.
Firstly GN vertical cuttings dryer system will separate the oil based drilling cuttings from the materials collected from the rig site both in onshore and offshore, and get the waste water with oil, the oil content remained in the cuttings after treated by GNCD930D-VFD is around 5%, you need to transfer the cuttings to thermal unit to reduce oil content in the cuttings then disposal, otherwise you need drilling waste injection process. For the waste water with oil, a 3-phase decanter centrifuge can help to separate the oil from the waste water, and oil recovery can be re-used for the drilling fluids and save a lot of drilling cost, the waste water can be flocculation and feeding to the water treatment system.Such drilling waste water treatment process can apply both vertical cuttings dryer and decanter centrifuge or both of them, it depends on your budget of the projecct. But you should pay more attention to the solids particle size, it is very fine clay and silt solids, the vertical G dryer can not be applied, the decanter centrifuge is suitable for such situation.
The sudden crude oil price fall down caused the operators want to reduce their production cost, less the equipments’s purchasing value is a good and effective way. GN solids control with GN solids Ameria office and warehouse in Houston, provide service both for sales and rental. We have 10 units 4-panel shale shaker, 5 units of mud cleaner( desander, desilter, shaker 3 en 1), 3 units of high speed decanter centrifuge, 1 set of VFD centrifuge in stock for rental and sales, welcome to contact us at 6710 windfern road, Houston, TX 77040 or visit us at OTC 2015 Reliant Arena Hall, 6137 & 9225-2.

GN Mini Decanter Centrifuge

As everyone knows, when explore minerals the drillers usually use core drilling. The size of the holes could be arrived at from some hundred’s ft with a hundred’s ft. Diamond experts can evaluate the composition from the minerals by doing a bit of experiments around the retrieved core samples. In line with the evaluate information from the diamond experts, the drilling company can decide whether or not they will begin the drilling or find another areas.

Core drilling plays an essential role within the mineral mining. Among the key important tools throughout drilling, decanter centrifuge will help separate the drilling solids effectively.

GN mini decanter centrifuge (type GNLW 223) is really a special designed centrifuge utilized on core drilling. Because utilized in the core drilling, you will find very little solids in comparison towards the oil drilling process.

So far, you will find some nations are utilizing GNLW 223 decanter centrifuge, for example Canada, America, Chile etc. GN solids control is creating decanter centrifuge for mining gemstone core drilling, this decanter centrifuge is comparable with MI-SWACO CD250 however the cost is extremely low. So that all these offered tools to Canada, America and Chile for mining drilling information mill gathered good remarks because of their excellent performance.

Why GN mini decanter centrifuge can sell such well in Mining industry, and it has a great fame in diamond drilling industry along with the coal mattress methane drilling industry? The only real response is the big talents of the decanter centrifuge.

With this mini decanter centrifuge, the bowl diameter is nine inch and also the length is just twenty-six inch. With this particular small dimension little structure, it’s quite easy to operate and simple for maintenance.

GN has utilized wear resistance materials (SS 304) to help make the bowl of the decanter centrifuge. Certain parts are utilizing tungsten carbide for any better protection and longer existence usage.

GN also offers the big decanter centrifuge for bigger dealing with capacity, for particulars thanks for visiting e-mail us.

A new solids control system produced by GN solids control can save your drilling cost extremely, especially under the situation that Brent crude oil prices fell below $49 a barrel and U.S. crude also fell more than $1 on Monday after the global economic outlook darkened and Iraq announced record oil production. You have to reduce your production cost in everywhere to fight with the low crude oil price, otherwise you can not earn money and keep your business going well.

The benefits to use proper solids control equipments have been emphasized for many times, like

1 Drilling fluid maintenance cost, clean up, and disposal cost, more fluids can be reused for drilling to save your money

2 Reduce your pressure from regulations of environmen protection

3 Less the overall cost of drilling

GN solids control system can be completely customized design according to your rig model and rig site layout. We have experienced engineer team who can give you professional solutions for all kinds of drilling/ boring engineering, including oil & gas drilling, geothermal drilling, water well drilling ,coal bed methane, horizontal directional drilling, diamond core drilling.

Recently GN solids control shipped 3 sets of 1000 HP drilling rig solids control system for a drilling company in Europe, not only in Europe, our solids control system has been sold to over 60 countries in the world, and we can meet the high standard requirement for Australia, New Zealand, Europe, South America and also for offshore project.

These 3 sets of solids control systems are exported to Europe, all motors and electric control panels are ATEX certified and all machines are CE certified. GN Solids Control is one of the few companies in China who can meet such requirement. And in other developed area like North America, we provide solids control system with IEC ex certificate.

GN designed vertical G dryer waste management system can be used for both water based drilling cuttings and oil based drilling cuttings, and the field test result is proved successful. The standard vertical G dryer waste management system including: verti-G dryer GNCD930D-VFD, decanter centrifuge GNLW363CG-VFD, Nemo pump GNG30-075 for feeding the centrifuge, Nemo pump GNG10A-040 for flushing the VFD decanter centrifuge and cuttings dryer, oilfield 3-runner design skid, V type fluids collection tank and accessories. This type tank is for easy tank bottom cleaning and avoid of accumulation of solids in the tank bottom .

We have specially designed drilling waste management system for water based drilling cuttings, the benefit to apply for this system is :

1 Use Hi-G dryer to instead of Verti-G dryer, less the purchasing cost and less the electricity consumption

2 Less the flushing pump for the vertical G dryer

3 G-force of Hi-G dryer can reach 8.0G max, with 4-panel shaker screen and 2.73m2 large screen area for better separation. After treated by hi-G dryer, the liquid is feeding to decanter centrifuge directly.

But compared with Hi-G dryer, vertical G dryer treated the cuttings much drier, the solids can be removed directly by truck, but the solids separated by Hi-G dryer still remain around 40% humidity.

In water based mud treatment system, the centrifuge is normally installed on the highest telescopic frame for better solids discharge. But the shale shaker could be put it on the lower stand.

       But if for oil based cuttings, Vertical G dryer management system is the best option, we have utilized it in many rig sites in the world to test its performance, it is proved good according to our client’s feedback.

To check GN vertical cuttings dryer performance in the rigsite, pls check the video from GN website from the video page.
