Tank cleaning unit and oil waste separation system

As the manufacturer of tank cleaning unit and oil waste separation system in China, GN solids control has designed and produced customized tank cleaning unit and oil waste treatment system for our client.


GN automatic tank cleaning unit is a closed loop system to clean the mud tank , oil tank, chemical tank and slurry tanks. GN tank cleaning unit can supply fresh water to the high pressure tank cleaning machine/nozzle which is mounted inside the tank to be cleaned. By the tank cleaning continuous process, it will minimize the water consumption and manpower. The high pressure pump is installed on the one skid tank cleaning unit which is used to supply the fresh water to the high pressure cleaning nozzle. We have two different design for the tank cleaning unit, one is the one skid design, all the components are installed on one skid for convenient transportation; the other one is the 3 skid design, it is composed of suction and discharged skid, treatment skid, storage skid, each skid with DNV lifting frame for operation at offshore rig platform. We can provide CNEX, ATEX and IEC EX as per project requirement.


After treated by the tank cleaning unit, the fluids can be treated by three phase decanter centrifuge separation system for oil, water, solids separation, the treated water can be also supplied to the high pressure cleaning machine, the oil can be recovery and the solids for final disposal. The three phase decanter centrifuge GNLW364 is designed for solids liquid liquid separation, with capacity 5m3/h. The max speed is 3964rpm and max G force 3200G. The screw propeller is protected by tungsten carbide tiles for longer working life. The mud distribution nozzle is protected by tungsten carbide inserts.

Automatic tank cleaning system

GN automatic tank cleaning system is a set of automatic tank cleaning system designed and manufactured customized according to client’s requirement. It is a closed-loop system used for continuous cleaning of mud tanks, oil tanks, and chemical tanks.


This automatic tank cleaning system supplies clean water to the vertical pipeline pump installed next to the mud tank, and the industrial hose pump feed the sewage back to the tank cleaning system for purification. The clean water is supplied to the vertical pipeline pump for continued circulation, thereby minimizing water consumption and labor costs.
The processing capacity of this system is up to 30m3/h which can operate continuously. It consists of three parts: mud tank, walkway guardrail, manifold assembly. The inlet is equipped with GN made filter, which can effectively avoid the damage caused by large particle solids to the hose pump, thereby improving system stability and service life.
The working principal of GN automatic tank cleaning system is as below:
Firstly, the tank bottom mud is sucked by the pump through the filter by the industrial hose pump, then discharged into the inclined plate clarifier through the static mixer in the discharge manifold of the hose pump. Through the dosing pump, the chemicals are sent into the static mixer and fully mixed with the mud.
Secondly the mixed mud is settled in the inclined plate clarifier, the solid is extracted by the diaphragm pump and discharged into the skip; The liquid overflows into the mud tank from the outlet of the inclined plate clarifier, pumped out by the vertical high-pressure pump, and discharged into the automatic spraying device for cleaning. Then, it is sucked back into the purification system by the industrial hose pump for further processing.
