CIPPE 2017 oil show is coming in March, next month, in Beijing, Capital of China. This is the largest oil show, with same reputation to OTC and ADIPEC.  Most client from South America, Latin America and North America will attend OTC; most client from Europe, Africa, Middle East will attend ADIPEC, and most client from Asia, Australia will attend CIPPE. Each oil show will cover about one thirds of the client in the world.

GN team in CIPPE 2016

Every year, GN Solids Control will show some news things to clients. This year, the most shining product should be the huge bowl centrifuge – 30inch bowl size, with max. treating capacity 800gpm. The bowl length is 132inch, and the ration of bowl length and bowl diameter is 4.2 to 1. With the design, client can handle huge volume mud with only one unit, smaller footprint equipment. With the professional design, the big bowl centrifuge is very fine for Tunnel Boring Project Mud Cleaning, Dredging Slurry Separation, and Municipal Sewage Sludge in Purification Plants, Industry Waste Water Treatment.

Another star product should be thermal desorption unit. TDU is key equipment to treat the oil based mud drilling cuttings, as last step the lower down the OOC to 0.3%. As per the government regulations, TDU is necessary equipment to treat the OBM cuttings.

The correct process should be: use the vertical cuttings dryer first to recover the useful based mud and return it back to drilling; the solids discharged into mud skip and transport every mud skip to mud plant with TDU, and use the TDU to burn the OBM cuttings, to make the final product environmental friendly.

If you are interested with solids control equipment, or you plan to China for the CIPPE oil show, pls send email to;  we can arrange car for you and offer necessary assistance.

GN Solids Control can provide various models Decanter Centrifuge, from mini size centrifuge to big bowl big volume centrifuge. The centrifuge is two phase separation centrifuge, which can be applied to oil drilling mud treatment, HDD drilling mud recycling, CBM drilling mud cleaning, Diamond drilling mud treatment, mining project etc.

As the beginning of New Year 2017, GN different model centrifuges are on sale, to celebrate the New Year and to feedback bonus to old clients.

1) 9inch mini size centrifuge for sale:

This centrifuge is very small size, which can be used for diamond drilling/mining project. The treating capacity is only 3-6m3/h, means 10gpm to 20gpm capacity. The bowl speed can reach up to 3800RPM, and we have both fixed speed option and variable speed option.

2) 14inch middle size centrifuge for sale – The most popular centrifuge model for oil drilling solids control

14inch centrifuge is the most popular centrifuge for solids control, mud weight reduce / barite recovery. Given the bowl size and treating capacity, GNLW363CG is equivalent to Swaco 518 / Derrick DE1000. In one project in 2015, GN sold over 30sets GNLW363CG decanter centrifuge to North Africa market. The centrifuge is still working very well for the drilling operation.

3) 18inch bowl centrifuge

We have one middle speed centrifuge with 18inch bowl size- GNLW452

and one high speed centrifuge with 18inch bowl size- GNLW453-VFD. GNLW452 is economic model specially for barite recovery. And GNLW453 is generally used for solids control/waste management. They have different application position.

4) 22inch big bowl big volume centrifuge

Big bowl big volume centrifuge can work for fast drilling, but generally the client prefer to middle size centrifuge for easier operation, and flexible application. And the client can buy more sets middle speed centrifuge to achieve big volume mud treatment.

We also have 30inch bowl size centrifuge, hydraulic centrifuge for sale. If you are in need of any them, pls let us know freely.


Shaker screen size is accurately defined by API size, it is range of separation points. But many client ask price of shaker screen in mesh number. How can we conversion the mesh number to API size? Different shaker screen have different calculation method. GN screen API size and separation points, pls check from GN website:

If you need more information, pls contact us freely.

Africa is not only good market for gold and jewelry, but also good market for energy, oil & gas drilling. As part of energy equipment company, GN Solids Control support the oil drilling market with mud treatment equipment.  Recently, we have one big project from Egypt; the client require about 30 thousand pcs of shaker screen. We submit all required documents, including shaker screen quotation, shaker screen brochure, GN company presentation, GN company API certificate and other certificate list etc.

Except for shaker screen, we also exported lots of other solids control equipment to Africa.

1) During 2013 to 2014, we exporting over 20 sets decanter centrifuges to Nigeria, with over 10 sets shale shaker, 3 sets vertical cuttings dryer.

The decanter centrifuge is mainly used for oil drilling solids control mud system. Usually, the client will match two sets centrifuge for one rig. One high speed centrifuge to remove the fine solids – cut down mud weight; the other middle speed centrifuge to remove big solids – recover the barite; GN can offer both fixed speed centrifuge or variable speed centrifuge for option.

Vertical cuttings dryer is used for OBM drilling waste treatment, dry the cuttings, recover the valuable base oil mud and return it back to active mud system for reuse.

2) In 2015, we also export over 30 sets centrifuge to Algeria, the client use the centrifuge for solids control, same function as mentioned above.
