GN’s engineer just finished the commissioning in West Africa for 4 units GNLW363 centrifuge. Besides the centrifuge, this customer also ordered the screw pump and screw conveyor from GN Solids Control.
All most all the countries within the territory of West Africa or near the Gulf of Guinea have rich oil reserves. It is proven that the oil reserves at gulf of Guinea have more than 80 billion BBL, which accounts for about 10% of the world’s total reserves. In past several years, a large percent of the world’s oil production increase belongs to Africa.
GN solids control has established contact with many oil industry customers coming from the West Africa countries. Some of the customers already placed order to GN even repeated orders.
Applications of GN Decanter Centrifuge
GN’s decanter centrifuge could be used for various applications, from primary solids control system barite recovery to ultra fine solids separation to drilling waste cuttings management, then to dewatering unit system. Barite recover always need a centrifuge with RPM 1600 to 2000, GN has a model of GNLW452 is especially for solids control barite recovery. Some of the drilling contractors would also equip one unit high speed centrifuge after the GNLW452 for ultra fine solids control separation.
GN could provide centrifuge with both fixed speed control panel and VFD control panel. Just like this West Africa customer, they bought GNLW363G-VFD for their waste cuttings management. GN’s VFD control panel for centrifuge could be designed as 3 various frequencies for main and back drive on centrifuge, and the third VFD is for the feeding pump. With the VFD control panel, GN’s largest model of centrifuge GNLW553 would be used as dewatering centrifuge for waster base drilling fluids colloidal size particles separation. By using VFD panel, the user could adjust the feeding rate and RPM according to specified slurry material and working conditions. Comparing with the fixed speed model, the VFD model has a more wide application.
