Recently GN Company received inquiries from Vietnam, South Korea, Bengal, ect for Mud Recycling System for their projects, including Piling, HDD, etc.

GN Company focus on manufacturing Drilling Mud Solids Control Equipment & Mud Recycling System for 11 years, widely used for Bored Piling, Trenchless HDD project, TBM (Tunnel Boring Machine), Water Well Drilling/Diamond Drilling Project, with turnover reached more than 25 million dollars in 2018, and exporting to about 75 countries, including Canada, USA, Kuwait, UAE, Singapore, India, Pakistan, etc.

A brief introduction about GN Mud Recycling System,

Feeding Mud (by pump) into GN Mud Recycling System, firstly the mud would be entered into bottom layer screen of shale shaker through buffer box, and big/coarse particles would be separated out, while mud fluid would flow into mud storage tank through the bottom layer screen.

Then centrifugal pump would take mud from storage tank for feeding into Desander Cone. Solid and Liquid would be separated because of Centrifuge Pressure. So solid would be discharged to the upper shaker from outlet nipple of desander cone, for separating fine solids. While Clean Mud would enter into intermediary tank through desnader cone overflow pipe.

Recently GN Company finished production of 10 sets of Decanter Centrifuges, ordered by a client from Middle East Company.

The model this client ordered is GNLW363, with bowl diameter about 360 mm, bowl speed 0~3200 RPM, and G force 3063 G, widely used for Mud/Sludge Dewatering, thickening, and different types of liquids clarifying.

GN Decanter Centrifuge working procedure is as below,

feeding the Liquid/Sludge into the decanter centrifuge, and both screw conveyor (within Bowl) and Bowl would rotate at a high speed, but different rate.

The solid and liquid would come into Two Rings separately, named Solid Ring and Liquid Ring.

While liquid’s specific gravity would be less than solid, so Liquid Ring would be closed to the Central Axis, and the Solid Ring would be closed to Bowl.

Because of the different speed of Bowl and Screw Conveyor, so Solid would be pushed to Cone end, while Liquid would be pushed to other end.

GN is a professional manufacturer Decanter Centrifuge for 11 years, and supplying about 250 sets for International market every year, including USA, Canada, Netherlands, UK, Australia, UAE, China, etc.

GN can supply from 9 inch (220mm) to 30 inch (760mm), with bowl length and diameter ration up to 4.2, and adjustable G force is up to 3000G, to meet different requirements.

GN guarantees the goods for 14 Months after shipment or 12 months after commissioning whichever comes first.

CIPPE (China International Petroleum & Petrochemical Technology and Equipment Exhibition), OTC (The Offshore Technology Conference), and SPE Offshore Europe (OE) are the three biggest Petroleum Oil & Gas Exhibitions.
The CIPPE is the biggest Petroleum Show in Asia, an annual exhibition of petroleum and petrochemical industry, with exhibition space about 90,000 sqm, 1,800 exhibitors and over 117,000 professional visitors from 65 countries, including USA, Germany, UK, France, Canada, Italy, Russia, Korea etc.

CIPPE received great support from domestic oil giants such as CNPC, Sinopec Oil Engineering Machinery Company, CNOOC,  while some global reputable enterprises also participated in the exhibition.

GN Solids Control attended the CIPPE Beijing Show from March 27th~29th, 2019, and displayed our full product line-up, including Decanter Centrifuge, Shale Shaker, Screen, Pump (Centrifuge Pump & Vacuum Pump), Oil Sludge Treatment System, etc.

Decanter Centrifuge is mainly used for Solids and Liquid Separation, including the items as below,

Dewatering sludge/mud and suspensions
Thickening sludge or mud
Clarifying different type liquids
Classifying solids in a wet suspension by grain size
Separation of solids according to various densities

GN Decanter Centrifuge can be widely used for Drilling Mud Solids Control, HDD, TBM, Bored Piling, Mining Industry, Food and Beverage Industries.

GN Oil Sludge Treatment System can be widely used for waste oil sludge/sand from Raw Oil Tank, Refinery Plant, Drilling Site.

The treatment process is mainly as follow, firstly heating and chemical washing the oil sludge, secondly removing big size of solid by shale shaker, thirdly removing fine solids by decanter centrifuge, and fourthly separating water and oil.

The oil recovered from oil sludge can be sold to the refinery plant, as solid & water content in the oil is less than 3%.

Recently a farmer contacted our Houston office for help, as he has a big farm for growing up huge amount of Soybean, before he generally exported to outside American directly, now he prefer to do SPC, named Soybean Protein Concentration, that would brought him much more profit from Soybean Protein than exporting soybean directly.

He consulted with professional Lab in university for detailed SPC process, and what he wants from us is to do the separation job and concentration, as GN is a professional manufacturer of Decanter Centrifuge for 11 years.
