Two Big Bowl Mud Dewatering Centrifuge Units to South America

Each year, GN manufactures and sells 200+ sets of decanter centrifuges, and more than half of this number would be sold to the oil and gas industry. They are always used for oil and gas driling solids control, drilling waste management, drilling mud dewatering and oily sludge treatment.

Centrifuges are used in above mentioned facilities because of the decanter centrifuges’ characters. As the decanter centrifuges’ working principle, by means of the high speed rotating of the centrifuge bowl and the different rotating speed between the bowl and the centrifuge propeller, the solids phase and liquid phase would be separated to each port. A centrifuge’s ideal cutting point is between 2 to 5 microns.

Also as a solution provider for separating works, GN Solids Control can also design a turnkey solution for clients. Here is one of a recent project GN provided to a client in South America. The client purchased 2 sets of following:

1.Big bowl decanter centrifuge GNLW654. GNLW654 is one of the large centrifuges of GN Centrifuge family, but not the largest model. GN offers centrifuges from 9 inch diameter bowl to 30 inch diameter bowl. And the length diameter ratio can be made as 3 or 4. For electric control panels, GN use VFD control panels with smart control.
Dewatering unit with a 6000L capacity for flocculation.

2.A dewatering unit for chemical dosing, As mentioned, the ideal cutting point of a decanter centrifuge is from 2 to 5 microns. When there are particles too large for the centrifuges, there should be some other equipment for pre-treatment before the centrifuge, for example, a shaker. But when the particles are too small, we use a dewatering unit to add polymerinto the material to flocculate the particles into larger ones in order to be chosen out by a centrifuge.

3. A telescopic stand for each centrifuge.

4. Screw pump for decanter centrifuge feeding.
