GN oil sludge system is to use chemical to wash the oil sludge with heat to temperature of 60-70 degree. After washing the sludge wil be pump to GN sepeartion equipment to do solid and liquid separtion. The recycled water can be reused in the washing process, and the oil is clean enough to sell to the refinery company, the solids contain less than 2% oil which can be sent to biodegradation or thermal unit for final disposal if needed.

Recently GN have completed a small oil sludge system, It will be sent to oversea customers soon. GN have 2 different model, namely GNOST-05C and GNOST-15C for the oil sludge system according to diggerent handling capacity. The GNOST-05C is an advanced oil sludge treatment system designed for efficient and effective processing of oil sludge. It utilizes cutting-edge technology to separate oil, water, and solids, ensuring compliance with environmental standards.

The oil sludge system is meticulously engineered with a GNLW364FT decanter centrifuge, a chemical dosing system, and a mud feed screw pump, all housed within standard containers for enhanced transportation efficiency and ease of installation. This innovative packaging approach significantly boosts the maintainability and protection of the equipment, ensuring a long service life and minimal downtime.

Treatment Processes

heating and Pre-mixing module

There is a pre-mixing tank for the preparation of the material and then heat the material to 60-70 degree.

Screening module 

There is vibration screen in this module, in order to remove the corase particle there, and feed in the fine particule to the next module directly.

Chemical dosing unit

add some polymer here to help the decanter to make the solid and liquid separation more efficient.

Decanter centifuge module 

The material will be feed in the 2-phase decanter centifuge at first to do the solid liquid sepation, and then the separated liquid will be feed into the 3-phase decanter centrifuge to get the oil-water-solid separation.

The working principle of solid vacuum pump is mainly powered by compressed air, using vacuum suction loading and pneumatic positive pressure to convey materials. Crown's solid vacuum pumps are powered entirely by compressed air and are capable of conveying solid particles, powdered materials, slurries, highly concentrated sludge, oil-containing sludge, mineral slurries, and other bulk materials, etc.

The working principle of solid vacuum pump can be divided into the following steps:

Suction process: In the suction process, the volume inside the pump chamber increases, forming a low-pressure area, making the external solid material is sucked into the pump chamber.
Compression process: as the pump chamber volume decreases, the material is compressed, the pressure gradually increases.
Exhaust process: when the pressure in the pump chamber reaches a certain level, the material is discharged out of the pump through the exhaust port, completing a working cycle.


The main application areas of solid vacuum pumps include:

Conveying solid particles and powder materials: it is suitable for conveying all kinds of solid particles and powder materials, such as mineral slurry and high concentration sludge.
Environmental protection field: in sewage treatment and sludge treatment, solid vacuum pumps can effectively transport oily sludge and other bulk materials.
Industrial production: in the production process of chemical, food, pharmaceutical and other industries, solid vacuum pumps are used for material conveying and loading to improve production efficiency
