GN Solids Control provides turnkey solutions for oil and gas drilling mud treating, includes solids control, waste management and oil sludge treating. Last week, GN Solids Control delivered one large oil sludge treating system to a Chinese oil site.
GN Solids Control Oil Sludge Treating Systems are largely used to treat oil sludge from oil tank bottom, drill cuttings from oil site, oil sludge from refinery plant etc. Basically, any high density or large viscosity oil sludge can be treated by GN Oil Sludge Treating System.
This oil sludge system provided to that Chinese customer is a 15 m3/h treating system. It includes the following main treating equipment:
GN Pre-mixing unit is a pre-treating equipment. Mud agitator is fixed on the top of the mud tank, which also fixed with hot pipes along with the tank. Oil sludge is diluted in the pre-mixing unit first. Chemicals need also to be added in order to increase the flow-ability of the oil sludge.
2.Shaker Treating Unit
After treated by GN pre-mixing unit, oil sludge is feed into GN shaker treating unit by using a submersible pump. Shaker eliminate those larger solids/particles larger than one hundred microns. To protect the shaker screens from blocking, GN shale shake is fixed with spraying lines and anti-spraying cover.
3.Decanter Centrifuge (2 phase)
GN decanter centrifuge is a finer separating equipment. Solids larger 2 microns can be eliminated. After treated by GN decanter centrifuge, solids with oil is less than 3%.
4.Disc-Centrifuge (3 phase)
Disc-centrifuge is a 3 phase treating unit, it separate oil, solids and water. Recovery oil BS&W (base sediment and water) is less than 3%. And oil in the recovered water is less than 500~1000 ppm.
5.Chemical Dosing Unit
In order to have a better treating performance, a chemical dosing unit is used. It provides chemical to pre-mixing unit, shaker unit and decanter centrifuge unit.
