22inch big bowl decanter centrifuges unit for Kuwait Oil Sludge Treatment Company

As a manufacturer of decanter centrifuge unit manufacturer in China, GN solids control can design and produce different size decanter centrifuge, including 9 inch centrifuge, 14 inch centrifuge, 18 inch centrifuge, 22 inch big bowl decanter centrifuge, 25 inch centrifuge, 30 inch decanter centrifuge. Except for two phase separation decanter centrifuge, GN solids also produce 3 phase separation decanter centrifuge for solids, oil and water. The decanter centrifuge applications including drilling rig solids control system, drilling cuttings treatment system, oil sludge treatment system, dewatering unit, waste water treatment system, mining tailings treatment and construction slurry cleaning, etc.


We have 2 models of 22 inch big bowl decanter centrifuge, GNLW553-VFD and GNLW554-VFD. The bowl diameter is 22 inch (550mm), The bowl length is 71 inch (1800mm) or 91 inch (2310mm). The designed capacity is 500gpm, the typical capacity is 400gpm. The max bowl speed is 3000rpm, the typical bowl speed is 2500rpm, the max G force is 2719G, the typical G force is 1888G. The bowl speed and differential speed can be adjustable by VFD control panel operation.
The oil sludge is a mixture of oil, water, and solid contaminants that can result from oil spills, tank cleaning, or oil production processes. Proper treatment and disposal of oil sludge are critical to mitigate environmental damage and recover valuable resources.


GN oil sludge treatment system working process is as below:
The vacuum pump pick up the oil sludge or contaminated soil from waste pit and discharge to pre-mixing tank, by adding chemicals, heating and agitating in the pre-mixing tank to improve the separation efficiency of the further separation equipments. After screening module, the treated fluids will be feed to big bowl decanter centrifuge to separate to solids and liquids ( oil water mixture), working with chemical dosing unit and heating if need.

Solids Control Decanter Centrifuge unit for Europe Drilling Company

Recently one package of solids control decanter centrifuge unit are ready for delivery to Europe Drilling company. The decanter centrifuge unit consists of VFD decanter centrifuge, telescopic skid, feeding pump and other accessories, like hoses, valves, pipes, control panel, etc.


The decanter centrifuge is a 14 inch bowl variable frequency drive decanter centrifuge, with bowl length 50 inch, the max speed is up to 3900rpm with max G force 3063G. The bowl main material is duplex stainless steel 2304, the other components are made of stainless steel SS316L, the bearing is from SKF brand, the screw is made of stainless steel with tungsten carbide tiles for longer working life. The solids discharge port and fluids outlet are all protected by tungsten alloy which is interchangeable. The positive pressurized VFD control panel can be widely used for different drilling conditions, including high temperature area, cold area, etc. The VFD drive is from ABB, YASKAWA, the main components are from Omron, Siemens, Schneider, etc. brand for easy source of replacement.


Additionally, we can make customized design for lifting frame of the decanter centrifuge, VFD control panel and telescopic skid to be utilized for offshore and onshore projects. The telescopic skid is also customized for onshore and offshore projects, it depends on the space at the rig site.
As one of the solids control decanter centrifuge manufacturer in China, GN solids can provide different explosion proof standard decanter centrifuge with different size for their applications, we have ATEX, IEC EX, CNEX for option, we can produce 9 inch bowl mini centrifuge, 14 inch and 18 inch bowl solids control decanter centrifuge, 22 inch big bowl big volume centrifuge and 30 inch bowl decanter centrifuge. We can also provide 3 phase decanter centrifuge for oil, water, solids separation for oil waste treatment and oil sludge separation system.
