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.
