Oil Sludge treatment equipments manufacturer in China

Oil sludge treatment equipments, Solids control equipments and drilling cuttings treatment equipments are major equipments produced by GN Solids Control. We can design and produce customized oil sludge treatment system and equipments as client’s requirement. Generally, GN oil sludge treatment system is to use chemicals to wash the oil sludge by heating to 60-70 C degree.


After treatment, the user will get required oil, water and solids. The recycled water will be reused in the circulation system, the recycled oil will be sold or for other use, the discharged solids will be send for final disposal or to further treatment unit.
The oil sludge from crude oil tank cleaning, refinery plant waste oil sludge, drilling waste sludge can be treated by the oil sludge treatment system, including sludge vacuum pump, pre-mixing & heating module, chemical dosing unit, coarse solids separation module, 2 phase decanter centrifuge separation module, 3 phase centrifuge separation module. The major equipments including: Double deck shale shaker, vacuum pump, 2 phase decanter centrifuge, 3 phase decanter centrifuge, screw pump, submersible slurry pump, mud tank with heating lines and accessories.


When using the vacuum pump to pick up the oil sludge from waste pit, an air compressor is used to supply air for the operation, it is a 100% air operated pump without electricity. The discharge horizontal distance is 500 ~1000m, if the outlet pipe size is bigger than inlet pipe size, the transfer distance will be sacrificed. The vertical picking up depth is less than 3m, the clear water picking up depth is up to 9vmeters.
We have GNOST-02C, GNOST-05A, GNOST-15A with 2m3/h, 5m3/h, 15m3/h capacity for option. If you need to get high quality oil and water, lower operation cost and maintenance cost, simple operation, less oil on the discharged solids, pls contact with GN sales engineer.

Two Sets GNOST-05C GN Oil Sludge Treatment System for Overseas Client

Recently 2 sets of GNOST-05C oil sludge treatment system are ready for delivery. The oil sludge treatment system is customized design as per client’s requirement, including pre-mixing tank module, chemical dosing unit, three phase decanter centrifuge separation module and three phase disc centrifuge separation module.


The pre-mixing tank module is used to receive the oil sludge from picking up pump, supply heating steam to the pipelines inside mud tank to heat the oil sludge up to 60 ~70°C, add proper chemicals and the mud agitator will mix it continuously, the screw pump will transfer the well mixed oil sludge to 3 phase decanter centrifuge separation module together with chemical dosing unit.


The 3 phase decanter centrifuge module consist of 3 phase decanter centrifuge, mud agitator, water collection tank, oil catching tank, to get discharged water, oil and separated solids.


The 3 phase disc centrifuge separation module consists of 3 phase disc separator, oil buffer tank with oil pump, water buffer tank with water pump, the oily fluids is feed to three phase disc separator to get clear water, oil and few solids. The separation result of 3 phase decanter centrifuge and 3 phase disc centrifuge is different to meet different client’s treatment requirement, the maintenance cost and operation procedure is also different.
GN solids control have 3 models standard oil sludge treatment system with 1m3/h, 5m3/h and 15 m3/h treating capacity, which can be used to treat refinery oil tank bottom cleaning oil sludge treatment, drilling waste treatment, oily waste water treatment, we can also provide customized modules oil sludge treatment according to different projects. Except for oil sludge treatment system, GN also design and produce water based drilling cuttings treatment and oil based drilling cuttings treatment system, if you need a drilling waste management solution, pls contact with GN solids sales.

Double Deck shale shaker and cuttings dryer for Africa drilling company

One set of double deck shale shaker and one set of vertical cuttings dryer are ready for shipment to Africa for drilling cuttings treatment system.
The double deck shale shaker will be applied as high G force drying shaker to separate the coarse solids, it can be used for both water based drilling cuttings and oil based drilling cuttings. The anti splash cover on the top to prevent the drilling mud from splashing. The top layer and bottom layer total 6pcs shaker screens are composite material frame for longer working life and better separation performance.


The vertical cuttings dryer is ideal equipment to be used for oil based drilling cuttings treatment, after treatment, the oil content on the cuttings is below 5%, the fluids will flow to an intermediate tank, then feed the fluids to decanter centrifuge for further treatment, the fine solids will be separated out by decanter centrifuge, the fluids can be reused for drilling. Before treated by decanter centrifuge, the fluids can be treated by drying shaker to reduce solids content, it will increase the decanter centrifuge treating capacity and performance, also it can prevent the centrifuge bowl from damaged by the high solids content.


GN standard drilling waste management system GNCM-40A is consist of VFD decanter centrifuge, vertical cuttings dryer, flushing pump, centrifuge feeding screw pump, fluids collection tank, skid, electric control system, accessories. The compact design with small footprint is loaded into standard container.
Except for drying shaker and vertical cuttings dryer, GN solids control also produce drilling waste treatment decanter centrifuge, including high speed decanter centrifuge, VFD decanter centrifuge, Fully Hydraulic Drive decanter centrifuge, we provide different explosion proof standard for option, IEC EX, ATEX, CNEX.
