The disc centrifuge flushing unit include a flushing tank, a water pump, the function as operation water and flushing water. The solids discharge unit include a solids collection box, solids discharge pump and pipeline connected to shaker tank.
   GN can design and produce standard oil sludge treatment system, GNOST-02C with 2m3/h treating capacity, GNOST-05A with 5m3/h treating capacity, GNOST-15A with 15m3/h treating capacity. Also we can produce customized oil sludge treatment system as per client’s requirement. If you need a oil sludge treatment solution, pls contact with GN solids.

As a tank cleaning unit manufacturer in China, GN produced automatic tank cleaning system mainly consist of 3 components, tank cleaning unit, buffer tank, inclined plate clarifier (IPC).

The general working process is as below:
The high pressure centrifugal pump transfer the clean water from buffer tank to tank cleaning unit to clean the mud tank. GN provide automatic flushing gun to clean the mud tank, which can be designed as skid mounted with frame for offshore drilling application. According to client’s requirement, we can design 1 unit flushing gun or 2 units of flushing gun according to client’s requirement.
The suction pump transfer the washed water from mud tank through the strainer ( to filter the coarse solids bigger than 2mm), then through the static mixer to inclined plate clarifier. In the meantime, the chemical dosing unit supply chemical to the static mixer with the washed water to improve the separation efficiency in the inclined plate clarifier.
The inclined plate clarifier separate the settled solids out and the treated water will overflow to buffer tank. The membrane pump will take out the settled solids from IPC to waste box.
The whole tank cleaning unit can be controlled by the explosion proof control panel on the skid.
After long time operation, the solids control system mud tank need to be cleaned due to the accumulated solids on the tank bottom, which will influence the mud density, to keep the drilling fluids balancing, tank cleaning unit is necessary to be applied.
Except for tank cleaning unit, GN solids control also produced oil sludge separation unit to treat oil tank bottom oil sludge for oil recovery, solids discharge and water treatment. If you need mud tank cleaning machine, tank cleaning slurry treatment unit, oil sludge treatment system, pls contact with GN sales engineer.

Recently one complete set of automatic mud tank cleaning unit are ready for shipment for offshore drilling platform to our international client. The automatic mud tank cleaning unit consist of the modular below:

1. Automatic Flushing Gun , 2 sets of automatic flushing gun are installed on one skid with lifting frame for offshore lifting application.
2. Mud Suction Unit, the peristaltic type pump sucked the sludge from tank bottom, it can be widely used to suck the sludge with either coarse solids or fine solids, weather with high content or not.
3. Mud Clarify Unit, it is also called inclined plate classifier, it is a equipment to separate the solids which can be transferred by the bottom installed screw conveyor to waste storage box. By using chemical dosing unit to add flocculants, the fine solids can be separated out easily.
4. Mud Storage and Transfer Unit, the treated water is storage in the mud storage tank, the water can be reused in the circulation system for tank cleaning by transfer pump.
5. Waste Cuttings Box, the discharged solids from mud clarify unit will be discharged into waste storage box, when it is full, it will be dumped by crane or forklift.
   Why need to use automatic mud tank cleaning unit for offshore drilling platform?
   After long time operation, fine solids will accumulate in the tank bottom, which need to be cleaned. The traditional method to clean mud tank will take 5 hours with 4 workers, it is a time and labor cost consumption cleaning method. GN automatic mud tank cleaning unit will make the cleaning much easily, reduce the labor cost and reduce the cleaning time. GN produced automatic tank cleaning unit can be widely used for drilling mud tank cleaning by using high pressure flushing nozzles. If you need more information, pls contact with GN solids sales.

As one of the shale shaker and decanter centrifuge manufacturer in China, GN solids control have some shale shaker and decanter centrifuge in stock for fast delivery to meet client’s requirement. The stocked items list is as below:

1. Shale shaker GNZS595F, 8 units, the shaker screen size is 585 x 1165mm, 5pcs shaker screens, the shaker screen dimension is interchangeable with GNZS594F shale shaker.

Recently one unit of mini solids vacuum pump and mini decanter centrifuge are ready for shipment for international customer. The mini solids vacuum pump is used for tank cleaning application, the mini decanter centrifuge is used for solids liquid separation.
GN solids control can produce vacuum pump with different flow rate, we have GNSP-40B, GNSP-20B, GNSP-10B for option, also we have GNSP-05B as Mini bilge cleaning sludge vacuum pump. The technical specification is as below:

Max flow rate is 5m3/h for clear water, inlet and outlet size is 2 inch and air intake hose size is 1 inch, the vacuum degree is 85Kpa/25 inch HG( Mercury Column), the discharge head is 80m and pressure is 116PSI. The max horizontal discharge distance is 500m. The max solids content is 80%, and max solids size allowed to be sucked is 30mm.The pressure required is 550 ~ 690 Kpa and air demand is 4.3 m3/min ( 150 CFM). The mini vacuum pump can be used for the cleaning of residual waste inside the cabin and the transportation of loose materials. The higher flow rate vacuum pump can be used to transfer drilling waste, oil waste, crude oil tank bottom cleaning sludge, oil sludge, sand, contaminated soil and other sludge, especially it is 100% air operated pump which can be safely used in electricity limited area.

The mini decanter centrifuge with 9 inch centrifuge bowl, we have different models for different applications. GNLW223D baby decanter centrifuge with bowl length 26.4 inch, it can be widely used for diamond core drilling waste water treatment. If the user need a higher treating capacity and need the discharged water more clear, they can select a longer bowl length 36.4 inch, GNLW224ET-VFD.
