GN 30 INCH BOLW CENTRIFUGE ON JOBSITE

Like among the GN Solids Control’s centrifuge models, the fixed speed 14 inch diameter bowl GNLW363 series centrifuges and GNLW452 decanter centrifuge with 18 inch diameter bowl are widely used for the oil and gas drilling solids control systems for the barite recovery. The VFD controlled GNLW363G, GNLW453 and GNLW553 series decanter centrifuges are used for the drilling cuttings waste management when working with a GN high G drying shaker or a GN Vertical cuttings dryer which are respectively for WBM and OBM and drilling fluids treatment projects, when working together with a chemical dosing system. GNLW223 and GNLW224 decanter centrifuges are mostly used for the diamond drilling projects and some projects with small treating capacities.
GNLW764 decanter centrifuge is a newly designed decanter centrifuge with a 30 inch big bowl, and a length bowl ratio as large as 4. It is specially designed for the big TBM projects, working after the shale shaker and desander plant. In some clients’ jobsite, there are 2 parallel desander units, each including one GNZS594 shale shaker and a GNZS594-2S12N mud cleaner. All fluids after treated by the 2 desander unit are transferred to the giant decanter centrifuge. On inlet of decanter centrifuge, there is a set of GNDW2000 Dewatering unit, it is used for chemical dosing for the centrifuge. It has 3 chambers for adding different chemicals for flocculating the extra fine particles into bigger ones, in order to be separated out by the centrifuge. Although after flocculation, the decanter centrifuge’s treating capacity is greatly reduced, GNLW764 could still handle a large capacity upto 90 cbm per hour.
Except for the giant centrifuge, other sections of the system are all designed into 20 ft containers. Even the shaker and mud cleaner are in frames with container corners. It is easy for transportation and layout.
