IECEX Explosion Proof VFD Decanter Centrifuge for Middle East Client

One batch of IEC explosion proof VFD decanter centrifuge are ready for shipment to Middle East, including VFD decanter centrifuge, VFD control panel, feeding pump and telescopic skid package.


Except for VFD decanter centrifuge, GN solids control also produce high speed decanter centrifuge, middle speed decanter centrifuge and fully hydraulic drive decanter centrifuge. Not only two phase decanter centrifuge, we also produce three phase decanter centrifuge. It can be applied for oil and gas drilling solids control system and drilling waste management system, oil sludge treatment system, also it can be used for HDD tailing slurry separation, mining slurry separation, construction engineering mud cleaning and other waste water treatment.
GN decanter centrifuge features including:


1. The bowl main parts are made by centrifugal casting and made of duplex stainless steel SS2304, superior to the performance of SS 314 and SS316.
2. The main material of the screw assy is duplex stainless steel SS2304, superior to the performance of SS314 and SS316L.
3. The screw propeller is protected by tungsten carbide tiles and it is replaceable, the working life is much longer than hard facing wear resistant coating layer.
4. The slag discharge port is protected by replaceable hard alloy sleeve.
5. The liquid outlet is also protected by replaceable hard alloy sleeve.
6. The SKF high quality bearing ensure the reliable operation and long service life.
7. The bearing lubrication system is applied for big model decanter centrifuges, such as 22 inch, 30 inch bowl diameter decanter centrifuge, it can meet the requirement of heavy load and high speed operation, which can improve the service life of bearings.
8. Planetary gearbox with large transmission torque, smaller size, stable operation and easy maintenance.
If you need a good performance and high quality VFD decanter centrifuge, pls contact with GN solids control.

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.

Drilling Cuttings Vertical Dryer System for Middle East Client

Recently one set of drilling cuttings vertical dryer system are ready for delivery to Middle East Client, the client just finished inspection before delivery to inspect the fitting and performance of the vertical cuttings dryer system.


The vertical cuttings dryer system consists of the equipments as below:
1. Vertical cuttings dryer GNCD930G
2. VFD decanter centrifuge GNLW363D-VFD
3. Screw conveyor 2 sets, one as flushing pump of vertical cuttings dryer, one as feeding pump of decanter centrifuge, their control is inside the control panel of vertical cuttings dryer and decanter centrifuge. The decanter centrifuge VFD control panel
4. Screw conveyor, to transfer the drilling cuttings to vertical dryer system continuously. GN produced screw conveyor have been widely used to transfer drilling cuttings, waste sludge with high solids content but less moisture, industrial waste, etc. materials in the world. GN screw conveyor with each section standard length of 12ft, we can make it with different numbers of sections for different transfer length, as 12 ft with 1 section, 24 ft with 2 sections, 36ft with 3 sections, 48ft with 4 sections. There are sealing rubber between sections and fastened with bolts. The connecting shaft between the middle section and the adjacent blade shaft should be securely fastened with bolts, and the blades at both ends of the hinge bearing should have continuity. When the screw conveyor is installed slantly, GN produced telescopic bracket can be used for angle adjustment. The closed plate cover or grating cover can be selected as requirement.
5. Telescopic skid for decanter centrifuge and vertical cuttings dryer on one skid, for convenient transportation and operation. The telescopic skid can be made as integral skid or separate skid according to the site’s requirement.
