GN premium high standard high speed centrifuge is a perfect choice for drilling mud and drilling waste treatment. GN offer 14’’, 18’’ and 22’’ decanter centrifuge for drilling mud and drilling waste treatment. It can also be used for waste water treatment and other applications.

Some weeks ago, GN Solids Control company dispatched a batch of shipment for a middle east job site. There are high speed decanter centrifuge 14’’ and 18’’ included in the shipment.

Parameters of the 14’’ and 18’’ drilling waste decanter centrifuge for middle east jobsite:


1) All the centrifuges are made per international high standard. The centrifuge bowl is made from duplex stainless steel (SS2205) by centrifugal casting. It is more durable than SS316L or SS304.

2) All the centrifuges equipped with ATEX zone 1 standard explosion proof VFD control panel. The centrifuge VFD control panel is equipped with ATEX standard air conditional for cooling down. It is specially designed for the high temperature area, and especially suitable for the offshore drilling rigs in Middle East and Affric, where it is high temperature and with high humidity. The VFD control panel is controlled by PLC system for smart control. GN equipped touch screen and rod control board to double ensure the performance. Clients can choose suitable type per jobsite condition.

3) German brand NETZSCH pump have been equipped to feeding for the high speed centrifuges. All the screw pumps are with VFD control and controlled by the centrifuge VFD panel to get variable speed automatically.

4) The drilling mud and drilling waste decanter centrifuge will be put on a telescopic skid. Both the centrifuge feeding pump and the smart control panel is mounted on the same skid for compact design.

5) In order to cater for the offshore drilling rig lifting standard, all the centrifuges and telescopic skids is certified by DNV per DNV2.7-1 standard.

Russia is a very important market of GN. GN owns a good marketing share in Russia market. With the establishment of GN Solids Russia, there are more and more cooperation between GN group and Russia oilfield waste management companies.

Recently, a complete drilling waste management system has been dispatched for a Russia client. The system has been put in a 40ft container for fast moveable and also for keep warming the cold weather of Russia. It is not the first time for GN Solids Control company sent containerized system to Russia market. The system includes following equipment:

cuttings dyer

1) Containerized drilling cuttings vertical dryer system consist of one set of GNCD930 vertical cuttings dryer, catch tank, flushing pump and mud transfer pump.
2) Cuttings collection box for storage of drilling cuttings from the vertical cuttings dryer.
3) Feeding screw conveyor for transfer drilling cuttings from the oil drilling rig and sent to vertical cuttings dryer.
4) Drilling cuttings transfer pump for transfer drilling cuttings with more moisture.
5) Variable speed decanter centrifuge with feed pump for polishing the drilling mud recovered from the cuttings dryer.

Unlike the drilling waste management treatment, the wastewater separation request high bowl speed with lower differential speed (also called conveyer speed).

Why high differential speed (conveyer speed) cannot be used for wastewater treatment?

1) Firstly, the high differential speed (conveyer speed) will mix the fluids and the solids completely; the whole centrifuge will be like a mixing machine, rather than a separation machine.

2) Secondly, as there is normally the chemical used for wastewater treatment. The big differential speed (conveyer speed) may push the solids to the fluids outlet.

3) Furthermore, if there is chemicals dosed in the wastewater, it will generate foaming to the centrifuges.

So if your centrifuge faced above problems as above, you may need to consider reduce the differential speed (conveyer speed).

For GN design decanter centrifuge, the main drive motor driving centrifuge bowl through gearbox. The back drive motor driving propeller directly. And the gearbox ration is fixed for a centrifuge model. So how the differential speed (conveyer speed) of the decanter centrifuge can be reduced?

1) Firstly, as there is relationship between differential speed (conveyer speed), back drive motor, and gearbox ration, you can reduce the bowl speed to reduce the differential speed (conveyer speed).

With GN PLC smart control VFD decanter centrifuge, you can reduce the bowl speed directly on the VFD control panel.

For fixed speed centrifuge, you can change the centrifuge pulley and belt to reduce the differential speed (conveyer speed). It is the normal way for many professional mud service companies, as they are familiar with centrifuge running and maintenance. Fixed speed is lower cost.

For the new centrifuge users, PLC smart control VFD centrifuge is better.

2) With PLC smart control VFD centrifuge, the operator can also reduce the propeller speed through reduce the back drive motor speed. The differential speed (conveyer speed) can also be reduced in this way.

Option 2 Reduce the back drive motor speed is more recommended to reduce the differential speed (conveyer speed), in this case, the centrifuge can be running in high speed and lower differential speed (conveyer speed), it can get a better wastewater separation performance of the decanter centrifuge.

2016 is a big and import year for GN Solids Control. Although the economic environment is very bad and the low crude oil price have no good sign for recovery, but GN Solids Control keep growing and have deep business cooperation with more and more worldwide big companies.

April and May is a very busy month for GN people. Days ago, GN people finish their job for exhibition in Moscow Russia. 2016 Russia oil show MIOGE is a professional Exhibition hold in Moscow from April 18-21. It is the biggest exhibition in oil and gas field in Russia. Many neighbor country visitors come for the show.

GN Solids Russia, as GN Solids Control branch company in Russia, came for the show with following equipment. It helps the clients and visitor check GN equipment and quality on the exhibition.

1) GN takes a solids removing mud cleaner for the Moscow oil show. The mud cleaner is a 3-1 combination of shale shaker, desander and desilter. GN patend design make the desander separator high efficiency and very use friendly.

Firstly, the mud cleaner is very easy for screen changing with GN offered professional tools.

Secondly, a tool box on the machine makes the job more easy for the separator operators.

In another hand, the mud collection hopper under the desander desilter cones can be used as an under flow shale shaker. Operators no need to remove the hydrocyclone assembly and no need to amount a separate mud feeding box for the shaker.

2) GN Solids Russia takes a 14’’ high speed decanter centrifuge for the oil show. It is a VFD centrifuge with high speed for drilling waste management as well as for mud solids control and waste water treatment. GN Solids Control has some sets running in Baker Hughes jobsite and feedback well.

3) A vertical cuttings dryer is also come for the show. It is the 3rd generation vertical cuttings dryer especially design and made for OBM, SBM and WBM.

A mud cleaning system with a shale shaker tanks system and a mud cleaner system is ready for shipment. The system is a customized design per client’s special requirement. It is a 3-tank mud cleaning system for a middle east project. The 2-tank mud system will be service for HDD (horizontal directional drilling) rigs in middle east.

The HDD rig mud cleaning system is including below equipment:
