High speed gravity separation technology help GN Solids to produce high quality decanter centrifuge, to serve domestic and overseas clients, by offering solids control and drilling waste management solutions, to develop GN into China high end technology company.

GN has various model centrifuges for option with different bowl size and different capacity, with different speed to separate different size particles.
1) GN 9inch baby centrifuge with only 9inch bowl size, and treating capacity will be 3-5m3/h. Normally, mining project / diamond drilling will require the small centrifuge to give better performance of mud treatment. What’s more, the cost of small centrifuge is very cheap.
2) GN 14inch bowl centrifuge with 14inch bowl size, and ration of length to diameter is over 3, to guarantee on the separation performance. The treating capacity for drilling mud can reach to 15m3/h to 25m3/h per the mud weight, viscosity etc. This model decanter centrifuge is equivalent to Swaco 518 centrifuge, Swaco 414 centrifuge, Derrick DE1000 centrifuge etc.
Many drilling contractor stop centrifuge renting service of Swaco branch or centrifuge renting service of Derrick company, they come to GN to buy their own centrifuges, and GN can offer training on centrifuge operation and maintenance. In long term, the drilling contractor can save lots of cost on mud treatment.

3) GN 18inch bowl centrifuge with 18inch bowl size and there are two options:
GNLW452 with 1800RPM bowl speed, which is specialized for barite recovery; the price is much better.
GNLW453-VFD with 0-2500RPM bowl speed, which is specialized for fast mud weight cutting, the centrifuge is controlled by VFD control panel & AC for cooling. The price is relatively higher.

4) GN 22inch bowl centrifuge and GN 30inch bowl centrifuge.
The big bowl big volume centrifuge is generally used for construction, TBM machine, Subway construction etc. In the mentioned project, large volume of mud will be engaged, and big capacity centrifuge is necessary to guarantee on the project period.

As the drilling operation going on, more and more solids will come into the mud, lead to the arising of mud weight. The change of mud weight is not good for drilling operation. Decanter centrifuge is required to remove the solids, and control the mud weight.

GN industry centrifuges

GN Solids Control is China leading brand for oil drilling mud decanter centrifuge. We have different model centrifuge for option, including:

9 inch bowl baby centrifuge, this is popular for mining/ waste water treatment.

14inch bowl high speed centrifuge, this model centrifuge is equivalent to SWACO 518 centrifuge / Derrick DE1000 centrifuge. Fixed speed centrifuge and variable speed is available per the client’s request

18inch bowl big volume centrifuge, this model centrifuge has two options: GNLW452 and GNLW453. The two option centrifuge is used differently. GNLW452 is very popular for HDD drilling, or for barite recovery; GNLW453 variable speed can be used for fast drilling

22inch bowl big capacity centrifuge, this is only GNLW553-VFD centrifuge for tunneling or other field fast drilling.

30inch bowl centrifuge is designed for industry application.

For oil drilling application mud weight control, we recommend fixed speed GNLW363CG 14inch bowl centrifuge for better option.

  • Firstly, fixed speed centrifuge is much easier for operation than variable speed centrifuge.
  • Secondly, we can offer 2700RPM bowl speed centrifuge, 3200RPM pulley with belt as backup.
  • Lastly, the fixed speed centrifuge is much better price than variable speed centrifuge.

Centrifuge feed pump, we recommend screw pump, positive displacement pump. The pump motor is controlled by the centrifuge control panel.

Telescopic skid is for option. The client can compare the price from GN, and local fabrication price.

Except for centrifuge, vertical cuttings dryer is another popular item for oil drilling waste management. The client needs it to recover the valuable oil based mud and return it back for drilling operation. We have two options: GNCD930 series cuttings dryer and GNCD730 series cuttings dryer. The client can choose the proper model per request.

201611-22-high-g-drying-shaker

1) High G dryer with collection tank beneath.

The High G dryer is GN 4 panel shale shaker with up to 8G vibration motor, and 4pcs composite material shaker screen. The high G force and longer deck can make the solids discharge much dryer, which is easier for transportation.  The clean mud will drop down to the beneath catch tank.

2) High speed decanter centrifuge with mud catch tank

The decanter centrifuge is GN 14inch high speed centrifuge, which is the most popular model for oil & gas drilling. The 14inch centrifuge is equivalent to Swaco 518 centrifuge or Derrick DE1000 centrifuge. Many client used Swaco/Derrick centrifuge before, and shift to GN after knowing GN strength and high quality of GN centrifuge.

The high speed centrifuge can be set to 3200RPM, which can separate 2-5microns fine solids. The clean drilling mud drop down to the catch tank below. Then, the screw pump will transfer the clean mud back to drilling active tanks for reuse.

Above equipment system is more proper for water based mud treatment. For oil based mud cuttings treatment, Vertical cuttings dryer will give much better performance. GN vertical cuttings dryer have been put into market for over 3 years. The separation  point is mainly depends on the screen basket, 0.25mm/0.35mm/0.5mm opening for options.

GN Solids Control solids liquid separation decanter centrifuge have been working for oil drilling many years. The stable working performance and reliable life time win good reputation for GN Solids Control. And now we just published three phase  centrifuge for solids, water and oil three phase separation.

3-Phase-Decanter-Centrifuge

14-inch-decanter-centrifuge

Except for decanter centrifuge and three phase centrifuge, GN main market is still in drilling waste management and solids control equipment.

GN drilling waste management equipment including: vertical cuttings dryer, waste centrifuge, solidification unit, fixation unit, thermal desorption unit, etc. Drilling Waste management equipment is used to treat the solids mixture discharged from shaker, recover valuable drilling fluids for reuse and reduce the waste need to be treated in following stages.

For water based mud, client normal choose High G drying shaker, decanter centrifuge and solidification unit. After treatment of solidification unit, the solids can be buried in cement ponds as final step. For oil based mud, client need to use vertical cuttings dryer, decanter centrifuge, thermal desorption unit. Thermal desorption unit can get cuttings solids with oil below 0.3%, this standard can meet the requirement of most country’s government protection policy. Compared with water based mud, OBM cuttings treatment cost is much higher both in equipment expense and operation cost.

GN Solids Control equipment including: shale shaker, mud cleaner, shaker screens, desander, desilter, decanter centrifuges, mud agitator, centrifugal pump, screw pump, mud tanks etc. GN Solids Control mud system can form a close loop mud circulation with drilling rig and mud pumps. After the mud ready for drilling, the mud pump will suck from the mud system and feeding for drilling rig. The mud from drilling rig flowline will go back to mud tank system for cleaning, adjusting and go back to mud pump. The mud tank system generally include four stage mud treatment and will remove particles in different size by different stage, shale shaker stage, desander stage, desilter stage and decanter centrifuge stage. Two phase separation centrifuge is mostly used in solids control system, very few clients choose three phase centrifuge.

As GN drilling waste management system is working well for Russia clients, this is the fourth containerized type drilling cuttings management system sent to Russia oil Service Company. Big Clients from Russia always prefer this containerized design that could make all equipment indoor, to avoid the cold surroundings and ensure the machinery running smoothly in cold weather. Operator could run the equipment inside, and this standard container type is also convenient for transportation by sea.

160520 Waste Management

Vertical cuttings dryer is one of the important equipment for waste cuttings management system. The waste slurry can be separated into much dryer solid discharges and recover liquid after treatment of cuttings dryer. The cuttings dryer unit in this project is 4th generation model dryer with normal RPM of 900, equipped with air knife system and flushing system for cleaning of screen and liquid discharge ring during equipment running. This can also be used to avoid block inside the cuttings dryer.160520 Vertical DryerVacuum cuttings pump is used to transfer the waste material into the vertical cuttings dryer. The advantage of using the Vacuum cuttings pump is less limitation to locate it and this type pump works very well for high density waste transportation. As backup, we also provide one set screw conveyor for feeding the cuttings dryer in case the cuttings pump not fit for some special cuttings. Another set Screw conveyor is also provided to install under the dryer unit to transfer the solid discharges out to the container.

After treatment of cuttings dryer, the recovered fluids need to go to centrifuge for further treatment. The high speed Decanter centrifuge with bowl speed up to 3200RPM separation points can be about 5-10microns. Centrifuge can separate much fine solids with bowl speed range 2700RPM to 3200RPM. We match variable speed VFD control panel for easier operation. With PLC touch screen, the operator can adjust the centrifuge bowl speed, differential speed and pump feed speed very easily.

Additional, there is waste cuttings skip to collect the cuttings coming from the conveyor. This cuttings skips is also design and made by GN Solids Control with cover for hazardous material further transportation.
