Tag: 3 phase decanter centrifuge

Oil Sludge treatment equipments manufacturer in China

Oil sludge treatment equipments, Solids control equipments and drilling cuttings treatment equipments are major equipments produced by GN Solids Control. We can design and produce customized oil sludge treatment system and equipments as client’s requirement. Generally, GN oil sludge treatment system is to use chemicals to wash the oil sludge by heating to 60-70 C degree.


After treatment, the user will get required oil, water and solids. The recycled water will be reused in the circulation system, the recycled oil will be sold or for other use, the discharged solids will be send for final disposal or to further treatment unit.
The oil sludge from crude oil tank cleaning, refinery plant waste oil sludge, drilling waste sludge can be treated by the oil sludge treatment system, including sludge vacuum pump, pre-mixing & heating module, chemical dosing unit, coarse solids separation module, 2 phase decanter centrifuge separation module, 3 phase centrifuge separation module. The major equipments including: Double deck shale shaker, vacuum pump, 2 phase decanter centrifuge, 3 phase decanter centrifuge, screw pump, submersible slurry pump, mud tank with heating lines and accessories.


When using the vacuum pump to pick up the oil sludge from waste pit, an air compressor is used to supply air for the operation, it is a 100% air operated pump without electricity. The discharge horizontal distance is 500 ~1000m, if the outlet pipe size is bigger than inlet pipe size, the transfer distance will be sacrificed. The vertical picking up depth is less than 3m, the clear water picking up depth is up to 9vmeters.
We have GNOST-02C, GNOST-05A, GNOST-15A with 2m3/h, 5m3/h, 15m3/h capacity for option. If you need to get high quality oil and water, lower operation cost and maintenance cost, simple operation, less oil on the discharged solids, pls contact with GN sales engineer.

3 Phase Decanter Centrifuge for oil water separation to China ES Company

One unit of three phase decanter centrifuge is ready for delivery to China Environmental Science company for oil water separation.
The three phase decanter centrifuge working principal is as below:


The solids, oil and water with different gravity, so the generated centrifugal force is different. The solids with largest specific gravity will generate highest centrifugal force, the next is the heavy phase liquid ( water) and the light phase liquid (oil). Due to different centrifugal force, one solid layer and two liquid layer are formed. The solids to be pushed out by the screw, the liquids are separated out from their respective nozzles, the solids oil water separation can be achieved.


GN three phase decanter centrifuge is designed for oil water solids separation under 24 hours continuous working and easy operation & maintenance. The main components including centrifuge driving system, decanter bowl, screw inside the bow, centrifuge skid and VFD control panel.
The 3 phase decanter centrifuge is installed on the mud tank or on the telescopic skid with feeding pump, it has been widely used for oil sludge treatment system. The oil sludge can not be feed into the three phase decanter centrifuge directly, the sludge vacuum pump will pick up the oil sludge from waste pit to the pre-mixing tank, with chemical jetting, heating and agitating, the submersible slurry pump will suck from the pre-mixing tank to shale shaker module to separate the coarse solids and reduce solids content, the fluids discharged from shale shaker will be feed to two phase decanter centrifuge with proper chemicals for fine solids separation. The liquid treated by the 2 phase decanter centrifuge can be feed to three phase decanter centrifuge for oil water separation by adding proper chemicals.

Fully Hydraulic Drive Decanter Centrifuge GNLW363D-FHD for Asia Customer

Recently 6 sets of fully hydraulic drive decanter centrifuge GNLW363D-FHD are ready for delivery for Asia customer.
The fully hydraulic drive decanter centrifuge model is GNLW363D-FHD, the technical configuration is as below:


Bowl size and bowl length is 14 inch by 50 inch, the max speed is up to 3600rpm, the max capacity is up to 200gpm, the main motor power is 45KW, the driving system is VISCOTHERM Fully Hydraulic Drive system. As a leading solids control decanter centrifuge manufacturer in China, GN solids control can produce different size and different type decanter centrifuge, as VFD decanter centrifuge, high speed decanter centrifuge, middle speed decanter centrifuge, Fully Hydraulic drive decanter centrifuge, 3 phase decanter centrifuge, 3 phase disc separator, etc. Especially for the FHD centrifuge, both of the bowl and scroll are drived by hydraulic motor ROTODIFF and hydraulic pump unit by two hydraulic oil circuits. The advantages to use the FHD decanter centrifuge is that it can be used in high temperature ambient for heavy duty with differential speed, compared with the VFD decanter centrifuge, the FHD centrifuge can work continuously without influence of the hot weather.


The features of GN decanter centrifuge:
1. The bowl material is made of duplex stainless steel 2304from centrifugal casting
2. The screw material is stainless steel SS304
3. Screw protection is interchangeable tungsten carbide tiles
4. The solids discharge port and mud distribution port is protected by tungsten carbide inserts
5. The bearing is SKF brand
6. The FHD brand is VISTOTHERM fully hydraulic drive system
7. The electric control is PLC smart control and the main components are ABB, Siemens, etc. famous brand
The fully hydraulic drive decanter centrifuge will be installed on the telescopic skid, feeding by variable speed screw pump, for more information of FHD centrifuge, pls contact with GN solids control.

GN will show Second Generation 3 Phase Decanter Centrifuge at 2024 CIPPE Exhibition

GN solids control is going to participate in CIPPE 2024 exhibition next week, we will show the second generation three phase decanter centrifuge during the show. If you are interested in the 3 phase decanter centrifuge and want to know more information, welcome to visit GN stand at CIPPE 2024.
The exhibition information is as below:


Exhibition Name: The 24th China International Petroleum & Petrochemical Technology and Equipment Exhibition（CIPPE 2024）
Exhibition time: 25th-27th, March, 2024,
GN Booth No.: E2168
After moving to the new 80000m2 new facility, GN introduced new advanced machines and technologies, to develop more new equipments with new technology, the 3 phase decanter centrifuge is also updated according to our experience with clients. The 3 phase decanter centrifuge is widely used for oil sludge separation projects to separate oil, water, solids. The separation is flexible for different liquid phase proportion. The operator can use the adjustable impeller to adjust the pond depth of the heavy liquid conveniently during working. An adjustment mechanism causes the position of the impeller to change.
