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.
