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.

GN Solids Control will attend 2024 ADIPEC oil exhibition

GN solids control will attend 2024 ADIPEC oil exhibition, the exhibition information is as below:
Exhibition Name: ADIPEC 2024
Exhibition Time : 4 – 7 November, 2024.
Location: ADNEC (Abu Dhabi National Exhibition Center), Abu Dhabi
Booth No.: Hall 10, Stand #10453


What equipments/ technology will be showed at ADIPEC 2024?
GN Fully Hydraulic Drive decanter centrifuge: In the past years, GN already provided a large quantity of FHD decanter centrifuge in Middle East area for different projects, like drilling fluids treatment, drilling cuttings treatment, dewatering unit and other solids liquid separation system.
The hydraulic bowl and scroll drive system drives both of the hydraulic motor ROTODIFF and the bowl from hydraulic pump by two hydraulic oil circuits. The heavy duty FHD decanter centrifuge can be used in high ambient temperature area such as Middle East area and Africa with higher performance, the compact design with proper lifting frame can meet user’s lifting requirement with lifting certificate for offshore projects. GNLW363D-FHD is the most popular model fully hydraulic drive decanter centrifuge, with bowl size 14 inch, bowl length 50 inch, the bowl speed is up to 3600rpm, and the differential speed is 10~60 rpm.


GN solids vacuum pump: it is an ideal pump to transfer different materials, such as drilling waste, drilling cuttings, drilling fluids, waste, solids, various sludge, oil sludge, etc. It can be used freely for hazardous area application since it is 100% air operated pump, no need electricity. The horizontal discharge distance is up to 1000m, the suction distance is up to 50m, the transferred solids size is maximum 50mm or 75mm, the sludge solids content is up to 80%. It required an air compressor to supply air for operation.


Welcome to visit GN at ADIPEC 2024 for more technology and solutions for solids control & drilling waste.

Mini Shale Shaker and Decanter Centrifuge for International Diamond Core Drilling

One batch of mini shale shaker and mini decanter centrifuge are ready for delivery for diamond core drilling project. It is the core equipments for the diamond core drilling solids removal unit.


A complete solids removal unit consists of shale shaker, decanter centrifuge, centrifuge feeding pump, mixing hopper, mixing pump, mud gun( agitator), compact design mud tank and accessories. The function of the solids removal unit (SRU) is a closed loop fluids treatment system to recycle the water for mineral and diamond core drilling, the purpose is to reduce the water consumption, reduce the environmental impact, improve the drilling efficiency.
According to different drilling conditions, we have 2 models of mini centrifuge for option, GNLW223 is a standard mini decanter centrifuge with max bowl speed 4500rpm and max G force up to 2492G. We can also provide variable frequency drive for this centrifuge for smaller current in start if need. GNLW224-VFD is a high configuration variable speed mini decanter centrifuge with max bowl speed 5000rpm. Both of GNLW223 and GNLW224-VFD centrifuge with bowl diameter 9 inch, the bowl length is different, the client can select it according to their actual requirement.


GNZS752 is a 2 panel mini shale shaker, to separate the coarse solids from the diamond core drilling waste water, it can greatly improve the separation efficiency of mini decanter centrifuge, and protect the centrifuge screw. Without the mini shaker, the centrifuge bowl will be blocked frequently and damage very fast. GN mini centrifuge bowl screw propeller is protected by tungsten carbide tiles for longer working life, especially when the solids content is high in the waste water, it will improve the centrifuge working life greatly.
If you need a mini shale shake and mini decanter centrifuge or complete solids removal unit for core drilling, pls contact with GN solids control.

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.
