Oil and gas drilling, refinery, and crude oil production will all generate a large number of oil sludge waste.The oil sludge waste generated from drilling, refinery and crude oil production have complex composition, which may cause serious pollution to the surrounding environment and wasted resources. As this reasons, it is essential and necessary to treat the oil sludge waste, to reduce and minimize the waste in order to protect our environment.

GN Solids Control utilizes heating washing technology with chemical enhancing system to treat the oil sludge from oil and gas drilling and refineries. 2-phase / 3-phase decanter centrifuge and 2-phase / 3-phase disc centrifuge are used in GN oil sludge treatment system.  The major function of GN oil sludge treatment system is to reduce the solids and liquid waste volume before enter into superior processing equipment.

The water recovered from GN oil sludge system can be reused in the separation system, or use the water for injection. But the water cannot be discharged into environment. They need further slurry separation treatment before discharge. The recovered oil can be sold to refinery companies. The solids can be used as construction field material, like to to make bricks for road construction.

With suitable chemical dosing, below is the major parameters of soil, oil and water after separation from GN oil sludge separation system:

The Oil on Solids Discharged from Decanter Centrifuge is around 1-3%. The solids waste volume is greatly reduced, clients can send the solids waste to TDU company to treat. The cost will be much lower than you buy a TDU. As the cost of TDU and its operation cost is greatly high. Besides TUD, the clients can also use Biodegradation technology to further reduce OOC to 0.5% or less.

Recovery Oil from 3 phase centrifuge BS&W is around 2-3%. Clients can sell it to refinery company.

Oil Content in recovery water from 3 phase centrifuge is 1000-3000PPM. The recovered water can be reused for premixing tank inside the treatment system.
You can add a Water Treatment system to reach 50-100PPM (Oil Content, Water after treatment unit). Or you send the water to slurry treatment company to treat for you.
