oil sludge treatment system

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.

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.
