This week, a package of oil sludge treatment system was departed to an oil field service company in China. The unit will be used to recovery oil sludge from oil base drilling cuttings. The oil sludge treatment system including below items:
1) 2 phase decanter centrifuge. Material fed to 2 phase decanter centrifuge must be with solids content Less 20% and Particle Size less than 20mm.
2) 3 phase disc centrifuge. The solid phase material entering the three phase disc separator usually shall be reduced the solid content to less than 3% and the solid particles to less than 400 micrometers by the decanter centrifuge, then the three-phase disc separator can achieve the best effect.


3) Transfer pumps
4) Dewatering chemical dosing system with dosing pumps and automatic control system
5) Transfer tank and holding tanks for mud recovery and mud transfer.

The project is for processing oil and solid wastes in sludge storage tanks. After the oily sludge wastes have been pre-treated. After the oil sludge wastes have been treated by sieving, sand washing, demulsify, and finely screened, they have now achieved reductions and preliminary separation. After that, the oily sludge will be treated for three-phase separation.

Two phase decanter centrifuge and three phase disc centrifuge is used in the three phase separation process. After three phase centrifuge separation, the final outputs are soil, oil and water.

Chemical dosing system is used before 2 phase and 3 phase centrifuge separation to help for the removal of as more fine solids as possible.

Besides 2 phase decanter centrifuge, 3 phase disc centrifuge and chemical dosing sytem, GN Solids Control also offers other oil sludge treatment and transfer equipment, like 3 phase decanter centrifuge, high G drying shale shaker, mud cleaner, Vertical cuttings dryer, Drilling Cuttings Solidification Unit, Thermal Desorption Unit (TDU), oil water separator, sludge vacuum pump, screw conveyor, etc…
