Last week, GN Solids Control has finished the test of a 3 phase decanter centrifuge. The 3 -phase decanter centrifuge will be shipped to an Africa client for tank cleaning slurry treatment.

Besides to treat the oil slurry comes from tank cleaning, GN Solids Control 3-phase centrifuge is widely used for oil recovery or for dewatering treatment. Clients can use the 3 phase decanter centrifuge to treat oil sludge from drilling, drilling refinery, or from industries.

Centrifuge is a high speed separation equipment. The rotating speed is normally up to 3000rpm or more, and the G force is also great. They are used for fine solids separation. The feeding slurry for 3-phase decanter centrifuge should meet the standard that the solids content should less than 10%. And particle size should be less than 2mm. Otherwise it may block the decanter centrifuge or even wearing out the centrifuge faster. Some time, in order to help for the settle down of the fine solids, clients will use chemical dosing for flocculation.

Normally, clients want to know the oil recovery efficiency before they invest to buy the 3 phase decanter centrifuge. The situation in most job site is that, the oil, water and solids percentage is not fixed. Ihe rate is changeable per various source or various rigs. GN Solids Control tell clients that, after 3 phase decanter centrifuge, the oil content in water is less than 15. The oil content in solids is less than 2%. The operator can calculate the oil recovery percentage based on the original oil & water percentage before feeding into 3-pahse decanter centrifuge.

Except for 3-phase decanter centrifuge, GN Solids Control is capable to make various sizes of 2-phase decanter centrifuge, and various sizes of disc centrifuge. The 2-phase decanter centrifuge is widely used in oil and gas drilling, HDD drilling and water well drilling to recover the barite, and for the fine solids separation. The dis centrifuge is 3 phase separation, it is popular useds for oil sludge separation and and industry separation.
