decanter centrifuge

Recently GN Company supplied one set of Oil Sludge Treatment System for Asia client recently, with Model GNOST-05A, capability 5 m3/h.

The Oil Sludge generally is from Oil Tank, Refinery Plant, or Drilling Rig. GN Company’s system can be used for recollecting Oil, Water and Solids separately, with achieving result as follow, Oil Content in Solid < 2%, Solis & Water Content in Oil < 3%, and Oil Content in Water is 500~1000 PPM.

The main procedure is as below,
1. Premixing oil sludge with chemical and heating water.
2. Removing Coarse Solids (bigger than 100um) by Shaker.
3. Removing find solids (less than 10um) by Decanter Centrifuge.
4. Separating Oil, Water and little ultra-fine Solid by a Disc Centrifuge (vertical).

GN Oil Slugdge Treament system also provide chemical dosing module, pump, transferring pipeline and other accessories.

GN Company focus on manufacturing Industrial Separation & Conveying equipment for 11 years, including Decanter Centrifuge, Sludge/Solids Vacuum Pump, Screw Conveyor, etc.

Based on advanced manufacturing capability, GN can offer Turnkey Solution for Industrial Wastewater & Sewage Treatment, Oil Sludge Treatment, etc.

GN Company now has two factories under operation, and a third one under manufacturing now, with more than 100, 000 square meters totally, and supplying equipment to more than 75 countries.

Welcome to contact GN Company for technical specifications, working video and sales reference about our Oil Sludge Treatment System.

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.

A Middle East client ordered some Fully Hydraulic Driven (FHD) Decanter Centrifuges from GN Company, with centrifuge feeding pump.

Fully Hydraulic Driven Centrifuge is driven by Hydraulic Pump with two units of hydraulic oil circuits, one for Bowl drive system, one for Scroll drive system.

GN Company can manufacture and supply FHD centrifuge with bowl diameter from 9 ~30 inch, and provide professional Centrifuge Feeding Pump with 10~90 m3/h, 4~22 Kw.

Decanter Centrifuge

GN worked together with the reputable centrifuge hydraulic driving system manufacturer from Switzerland for developing this fully hydraulic system, in order to reach the requirement for high standard from the international market and the high-class market in China.

GN FHD Decanter Centrifuge has advantages as follow,

1. Centrifuge, Hydraulic Driving System, and Control System is installed in one skid, and it can be easy for rigging up.

2. Operator can control centrifuge with PLC system, which is easy, smart, and with safety protection.

3. The bowl and scroll is processed by high precision CNC machine and balanced by advanced balancing machine. Performance is stable and maintenance is less. Centrifugal casting technology makes the bowl material much denser to avoid bubble.

 

GN Decanter Centrifuge can be widely used for industries as below,

Environmental & Wastewater Treatment
