It is mainly used to treat the oil sludge coming from oilfield drilling cuttings, refinery oily waste and oil storage tank bottom sludge. Oil sludge treatment system is one of the separation solutions GN promoted in recent years. It is mainly used to treat the oil sludge coming from oilfield drilling cuttings, refinery oily waste and oil storage tank bottom sludge. 

GN has three standard models of the oil sludge treatment system per the treating capacity 1-2, 5-10, and 15 cubic meters per hour. The pictures showing is one of the GNOST-05A manufactured for a domestic client from oilfield. 

GN oil sludge treatment system is mainly consisting of below modules.
1. Premixing Module – this module includes mixing tank, agitators and transfer pump. The oil sludge is firstly put into the tank for diluting to make the sludge more flow able for easy treatment by subsequent module. Water and chemical will be added into the tank, with heating system increasing the temperature, the emulsified oil will take off from the solid to become the demulsified oil. 

2. Coarse Screen Separation Module – one unit high G force shaker is the critical equipment in this module. The coarse solids will be removed out by the mesh screen. To prevent the sludge spraying, the shake unit should be properly covered.   
3. 3-Phase Separation Module – this module is combined with decanter centrifuge package and vertical disc centrifuge package. The decanter is used to remove large percent of solid in sludge to reduce the solids content. The effluence will then fed to the disc centrifuge for fine oil, water and ultrafine solids separation. 

4. Chemical Dosing Unit – GN is able to provide the containerized chemical dosing unit to distribute the chemical to every module in the system. The containerized design make the module is easy for transportation. 

GN has already accumulated rich experience in making this type oil sludge treatment system. Plenty of case studies from home and abroad are available to share for reference. For more information on GN oil sludge treatment equipment, please feel free to contact.
