The treating capacity is 360m3/h, separation cut point is 30μm, the effective tank volume is 24m3, total power is 164KW, the shipping dimension is L6058×W2438×H3115mm, it can be shipped by bulk cargo vessel, the gross weight is 23000 kgs. The GNTBM-360 Slurry Separation Plant consists of 2pcs of 16 inch desander cone, 8pcs of 6 inches desilter cone, with desander desilter feeding pump 75KW, the desander cleaner is GNZS1536-2A with lower deck screen area 5.4m2, upper deck screen area 5.4m2, the deck angle is±3 °.The mud tank size is same with 20ft container size, the equipments on top of the mud tank with lifting frame for convenient lifting and installation. The walkway and guardrail around the mud tank for convenient operation, the control panel is installed for easy operation for people stand on the ground.


The working process is as below:
The transfer pump feed the slurry to the double deck shale shaker lower deck through the coarse screening inlet pipe, to remove the coarse solids from the slurry. The built in #1 slurry pump transfer the slurry separated by coarse screening to desander cone, the clean mud flow out from the overflow port, the cuttings is discharged from the desander drop in apex, and fall on the upper deck of the double deck shale shaker to recover more useful fluids. The built in #2 slurry pump feed the clean mud to desilter cone, the clean fluids flows out from the desilter upper part, and overflows to the storage tank outside the system, which can be reused for the TBM machine. The solids particles will be dried and collected for disposal.

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.

3 Phase Decanter Centrifuge for oil water separation to China ES Company

One unit of three phase decanter centrifuge is ready for delivery to China Environmental Science company for oil water separation.
The three phase decanter centrifuge working principal is as below:


The solids, oil and water with different gravity, so the generated centrifugal force is different. The solids with largest specific gravity will generate highest centrifugal force, the next is the heavy phase liquid ( water) and the light phase liquid (oil). Due to different centrifugal force, one solid layer and two liquid layer are formed. The solids to be pushed out by the screw, the liquids are separated out from their respective nozzles, the solids oil water separation can be achieved.


GN three phase decanter centrifuge is designed for oil water solids separation under 24 hours continuous working and easy operation & maintenance. The main components including centrifuge driving system, decanter bowl, screw inside the bow, centrifuge skid and VFD control panel.
The 3 phase decanter centrifuge is installed on the mud tank or on the telescopic skid with feeding pump, it has been widely used for oil sludge treatment system. The oil sludge can not be feed into the three phase decanter centrifuge directly, the sludge vacuum pump will pick up the oil sludge from waste pit to the pre-mixing tank, with chemical jetting, heating and agitating, the submersible slurry pump will suck from the pre-mixing tank to shale shaker module to separate the coarse solids and reduce solids content, the fluids discharged from shale shaker will be feed to two phase decanter centrifuge with proper chemicals for fine solids separation. The liquid treated by the 2 phase decanter centrifuge can be feed to three phase decanter centrifuge for oil water separation by adding proper chemicals.
