Exhibition location：Beijing, New China International Exhibition Center
GN Stand number：E2168

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.

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.
