What products will be showed at CIPPE exhibition?
1. The 4th generation Fully Hydraulic Drive decanter centrifuge, GN produced fully hydraulic drive decanter centrifuge have been widely used for onshore and offshore drilling fluids treatment. GN FHD decanter centrifuge can be used in high temperature for heavy duty mud with flexible bowl and differential speed. We can design and produce lifting frame and lifting pad which is comply with DNV 2.7/1 certificate to meet the offshore lifting requirement. ATEX explosion proof standard will be applied for class 1 div. 1 application. The hydraulic bowl and scroll drive system drives both the hydraulic motor ROTODIFF and the bowl of a decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits. The bowl material is made of duplex stainless steel SS2304 from centrifugal casting, the screw material is stainless steel 304, and the screw propeller is protected by tungsten carbide tiles for longer working life.


2. The lastest K Version brand new offshore oil and gas drilling fluids shale shaker
3. The lastest G version brand new three phase decanter centrifuge
4. Other solids control equipments: vertical cuttings dryer, big bowl decanter centrifuge, mud cleaner, screw conveyor, solids transfer vacuum pump
5. Drilling fluids shale shaker screens
We look forward to meeting you at CIPPE 2025 and having an in-depth discussion on the future development of the solids control industry. And we are just 1.5 hours drive from the exhibition hall, welcome to visit us after CIPPE.

GNZS752K Mini Shale Shaker for Brazil Company

Recently one batch of GNZS752K mini shale shaker are ready for shipment to Brazil company. The reference treating capacity is 200gpm, 2ea 1.0KW vibration motor drived the shale shaker, the G force is up to 7.5G, which is adjustable. The deck angle is +2°, it is not adjustable. The screen area is 1.35m2, installed 2pcs of composite material frame shaker screens. We can provide CNEX, ATEX, IEC EX explosion proof standard for option. We can offer both API RP13C standard shaker screen and slot screen to meet client’s different requirement. We have same model mini shale shakers widely used in Brazil for different applications.


The GNZS752K mini shale shaker consists of 2ea vibration motor, 2pcs shaker screens, electric control panel, skid, shaker basket, wedge, shock absorbing spring group, synchronous lifting mechanism, buffer tank, the anti splash device is for option.
The mini shale shaker can be used for oil and gas drilling mud solids control, oily sludge treatment system, HDD mud recycling unit, TBM slurry treatment, construction mud treatment, mining waste water treatment and other mud treatment.
The applications including:


Water well drilling
Geothermal drilling
Environmental drilling
Oil and gas drilling
Mining exploration
When you are considering a lower processing capacity instead of a big size shale shaker, and the budget is limited, GN mini shale shaker will be a good choice.
Except for mini shale shaker, GN also provide 3 panel shale shaker, 4 panel shale shaker, double deck shale shaker, tandem shale shaker for onshore and offshore oil and gas drilling, geothermal drilling and Horizontal Directional Drilling. Especially for the oil and gas offshore shale shaker, the features including higher flow rate capacity, various screen mesh size from API 20 to API 325, easy maintenance, corrosion resistant materials suitable for offshore environments, small footprint, compliance with offshore operation regulations.

22inch big bowl decanter centrifuges unit for Kuwait Oil Sludge Treatment Company

As a manufacturer of decanter centrifuge unit manufacturer in China, GN solids control can design and produce different size decanter centrifuge, including 9 inch centrifuge, 14 inch centrifuge, 18 inch centrifuge, 22 inch big bowl decanter centrifuge, 25 inch centrifuge, 30 inch decanter centrifuge. Except for two phase separation decanter centrifuge, GN solids also produce 3 phase separation decanter centrifuge for solids, oil and water. The decanter centrifuge applications including drilling rig solids control system, drilling cuttings treatment system, oil sludge treatment system, dewatering unit, waste water treatment system, mining tailings treatment and construction slurry cleaning, etc.


We have 2 models of 22 inch big bowl decanter centrifuge, GNLW553-VFD and GNLW554-VFD. The bowl diameter is 22 inch (550mm), The bowl length is 71 inch (1800mm) or 91 inch (2310mm). The designed capacity is 500gpm, the typical capacity is 400gpm. The max bowl speed is 3000rpm, the typical bowl speed is 2500rpm, the max G force is 2719G, the typical G force is 1888G. The bowl speed and differential speed can be adjustable by VFD control panel operation.
The oil sludge is a mixture of oil, water, and solid contaminants that can result from oil spills, tank cleaning, or oil production processes. Proper treatment and disposal of oil sludge are critical to mitigate environmental damage and recover valuable resources.


GN oil sludge treatment system working process is as below:
The vacuum pump pick up the oil sludge or contaminated soil from waste pit and discharge to pre-mixing tank, by adding chemicals, heating and agitating in the pre-mixing tank to improve the separation efficiency of the further separation equipments. After screening module, the treated fluids will be feed to big bowl decanter centrifuge to separate to solids and liquids ( oil water mixture), working with chemical dosing unit and heating if need.

Multiple sets of drilling rig mud tank systems have completed installation and commissioning work

Multiple sets of drilling rig mud tank systems have completed installation and commissioning work. The drilling rig mud tank system including shale shaker, desander, desilter/ mud cleaner, vacuum degasser, decanter centrifuge, trailer mounted mud tanks with tank accessories and roof cover, centrifugal pump, mud agitator, mud gun, etc.

As per client’s request, GN engineer will fly to client’s rig site to complete the installation and commissioning work. The installation and commissioning work including:
1. Functionality Check: Ensure that all components of the mud tank systems are functioning correctly. This includes mixing equipment, pumps, shakers, and other related machinery.
