GN 3 Phase Decanter Centrifuge for Waste Oil Recovery

Keeping improving is the major feature of GN Solids Control, and this could be proved by the continuously issued new products in GN’s line sheet. Just shortly before, GN published the 3 phase decanter centrifuge on the official website to tell customers that GN is able to provide this type decanter centrifuge which is very popularly used for recovering the waste oil.

The slurry treated by the 3 phase decanter centrifuge is consisting of two kinds of immiscible liquid, always water and oil, and solid. The 3 phases need have different density so that the centrifuge could separate much easier, as all the horizontal decanter centrifuges are separating the phases by centrifugal force.

GN’s 3 phase decanter centrifuge structure is not big different with 2 phase model. The difference is how the liquids discharged out of the centrifuge. The solids in the slurry should have much higher density than the liquid, and then the solids could be easily separated out, which will increase the efficiency of the separation process. Higher density liquid will be discharged out under the pressure, while the light liquid will flow out from the liquid discharge ports at the bowl end face.

3 phase decanter centrifuge is mainly used in separation of oil sludge containing oil from refineries. Oil refineries have many holding tanks for oil need cleaned regularly, always the operator will used high pressure water to flush the bottom of the mud tank, and this type mixed slurry is the main source of the material treated by the 3 phase decanter centrifuge. Some other industries like food industry, edible oil production, biofuel production etc will also widely use 3 phase decanter centrifuge.

GN solids control now could provide the 3 phase centrifuge with bowl size of 14 inch, 18 inch and 22 inch. Any of your inquiry about other equipments such as shale shaker, mud agitator, mud gas separator , shear pump etc. is welcomed.
