oil sludge treatment system

One set of oil sludge treatment system is ready for shipment for one client in China. The technical configuration for GN oil sludge treatment system is as below:


1) Pre-mixing tank modular: including mud tank, heating lines inside mud tank, handrails, walkway, pipelines, stairs, etc. Submersible slurry pump as feeding pump of shale shaker, mud agitator to mix the oil sludge after heating and chemical jetting process, liquid level meter and electric control system.
2) Coarse shaker modular: including mud tank with heating lines, shale shaker installed on the shaker tank with internal spray system and sealing cover, mud agitator to mix the oil sludge, liquid level meter, and mud tank accessories with lightings, electric control system.


3) Centrifuge modular: including decanter centrifuge with feeding pump, 3 phase centrifuge with flushing pump, decanter centrifuge installed on the mud tank to separate solids from fluids, the clean fluids flow to 3 phase centrifuge to separate oil from water, the pure oil is recovered and flow to buffer tank with liquid level meter. The pure water is flow to buffer tank with liquid level meter, it can be pumped to water storage tank automatically or back to the circulation to reuse.
4) Chemical dosing system to add chemicals in premixing tank and centrifuge package modular, all the accessories are installed in the container for convenient shipment and better production.


We have 3 standard models oil sludge treatment system for option, with 1m3/h, 5m3/h, 15m3/h, we can also design customized oil sludge treatment system for our clients. Our engineer will fly to client’s jobsite for first time installation and commissioning and training the client’s engineer.
Except for oil sludge separation system, we also produce automatical tank cleaning system, waste water treatment unit,oil water separator, slant plate clarifier. And we have vacuum pump to feed the water to the oil sludge separation system.

Recently 1 set of oil sludge treatment plant is almost ready for shipment to Asia client, it is under testing in our facility before shipment. The treating capacity for oil sludge separation is 5 m3/h. We also have standard or customized designed oil sludge separation system with 1 m3/h and 15m3/h for option.


The general working process is as below:
GN sludge vacuum pump transfer the oil sludge from the waste pit/pond to the pre-mixing modular, the pre-mixing tank equipped with heating lines which can heat the oil sludge to increase the flowability of the oil sludge and increase the separation efficiency of the shale shaker, decanter centrifuge. By adding the chemicals, it will also increase the efficiency of the further process steps. 2 mud agitator and one submersible slurry pump are installed on the pre-mixing tank with electric control system.
Then the pre-treatment oil sludge is transferred to the shale shaker to separate the coarse solids by the submersible slurry pump, it also reduces the solids content of the oil sludge so that the centrifuge could separate the fine solids easily. The shaker screen is specially made with big opening to separate coarse solids to protect the decanter centrifuge.
The screw pump feed the oil sludge to the decanter centrifuge, the discharged fluids is flow to the 3 phase centrifuge to separate the oil and water. The clean water and pure oil is flow to the buffer tank , which will be pumped to the oil storage tank and water storage tank. The water can be used for the circulation again.
The 20ft container loading dewatering unit will be used when necessary with decanter centrifuge, the chemical jetting is to make the oil mixture easily separated by the decanter centrifuge.
If you need a customized solution for waste oil sludge treatment, pls contact with GN sales for more information.

Last week, GN finished production of 2 m3/h oil sludge separation system for USA client, this week, we finished production for 15 m3/h oil sludge treatment system for Europe client, this is the repeat order for this client, they bought one unit of 1 m3/h compact design oil sludge separation system for the same project. They are satisfied with the separation result, so repeat order for a bigger treating capacity system.
The configuration of the containerized 15m3/h oil sludge separation system:
1) Premixing tank: The sludge vacuum pump transfer the oil sludge from the waste pit to the pre- mixing tank, which is equipped with heating line inside the tank around, and the mud agitator installed on the tank to agitate the oil sludge to prevent the solids from accumulation in the tank bottom. The system will be used in cold weather area, we put them in the container to keep the equipments warm.


2) Shale shaker tank, to separate coarse solids from the oil sludge, this is to protect the decanter centrifuge, coarse solids will wear the centrifuge screw very quickly, GN decanter centrifuge screw is made of stainless steel 304 by heating, the flights are protected by tungsten carbide tiles, it is fixed by special glue and bolts.


3) Decanter centrifuge modular: With one unit of 22 inch bowl decanter centrifuge installed inside the 40ft container, the screw pump is installed on the centrifuge skid, the screw conveyor is installed under the centrifuge solids discharge port to transfer the solids outside the centrifuge container.

One unit of 1m3/h oil sludge treatment system testing unit is shipped to Europe recently, this is for client’s urgent requirement, later the 15m3/h oil sludge separation system will be shipped next month for the same client.


The client has visited GN factory in Beijing twice, after factory inspection and business negotiation, they placed order for the 15 m3 oil sludge treatment system, and also the 1 m3/h oil sludge separation system for urgent purpose.
To check the working video of the 1m3/h oil sludge separation unit, pls check our website:

The main components of the system including:
1) 2 panel shale shaker to separate coarse solids from the oil sludge in case of any coarse solids will damage the decanter centrifuge
2) 2 phase mini decanter centrifuge to separate the fine solids maximumly from the oil sludge by mixing with chemicals, with fluids collection box
3) 3 phase disc centrifuge to separate the oil from water to get pure oil and pure water
4) Oil storage tank and water storage tank
5) Pre mixing tank with mud agitator, heating lines
6) Chemical dosing system
7) Shale shaker fluids storage tank with heating lines
8) Shale shaker feeding pump
9) Decanter centrifuge feeding pump
10) Tank skid for the all equipments

The system is originally produced to show at CIPPE oil exhibition, after the exhibition, we shipped the testing unit to a domestic client for testing their oil sludge treatment, they use the proper chemical jetting and get the satisfied result, then we shipped the unit back to our factory for cleaning, and prepare to test in other client’s jobsite.
