GN Oil Slurry Treating System

GN Solids Control has provided thousands of turn-key solutions to global customers. GN various separation treating equipment are widely used in solids and liquid separation, such as oil slurry treating, refinery plant slurry treating, oil tank bottom slurry treating.
This year, GN Solids Control has provided some sets oil slurry treating systems in Uganda, Kuwait, Canada and Qatar etc. GN Solids Control Oil Slurry treating systems are especially designed to treat high density and viscosity oil slurry: oil, water and solids can be separated out.
Solids discharged from GN oil slurry treating system only contains 1~2% oil; recovered oil only has less than 0.5% solids, while the recovered water is also less than 0.5% oil (by using gravity oil & water separator). If customer has higher demand on the recovered water, we also provide micro bubble oil & water separator. 20170704 Oil Sludge Treatment 2
GN Oil Slurry Treating System mainly includes the following treating components:
1. Pre-Mixing Tank
GN pre-mixing tank is used dilute the oil slurry by adding water and chemicals. Heating pipe around the tank is assembled in order to increase the liquidity. GN Solids also provides vacuum pump which can suck high density slurry from a mud pit within 10 m.
2. GN Coarse Shaker
GN coarse shaker is the first phase treating equipment, large solids are removed by choosing different size shaker screens, and sometimes opening mesh screens in stainless steel are also used. Here GN coarse shaker is covered with metal plate in order to keep the slurry from splashing. Flushing outlets also fixed on the shaker so screens don’t need to be disassembled for cleaning.
3. GN Decanter Centrifuge
Based on the treating volume, GN Solids provides 14inch centrifuge, 18inch centrifuge or 22inch centrifuge to treat different drilling slurry. 2 sets centrifuges may be used so solids can be removed twice.
4. GN 3 phase Separator
5. GN Flocculation Unit

GN Decanter Centrifuge Maintenance

GN Solids Control manufactures 9 inch, 14inch, 18inch and 20 inch decanter centrifuges. GN centrifuges are widely used for various solids and liquid separation areas, for example, industrial water, oil and gas drill cuttings, soil remediation, construction slurry etc.
All the workers must know how to operate centrifuge as different working parameters need to be adjusted which obviously affect the separating result. And know how to do some maintenance is also pretty important, here are 2 cases for reference:
1. The main motor belt alignment is not good. There is minor offset between the pulley on the gearbox and motor pulley. The motor pulley contacts the belt guard, because it is offset. Do you have any suggestion as to how we can fix this alignment?
Offset is a problem that we cannot ignore, as belt alignment will cause issues with the bearings or belts. This might happen when the centrifuge transported by long time transport without proper secure, but it’s very easy to adjust. Please check the following drawing for the motor position. Loose the 4 bolts (in red circle) under the main motor, and adjust the 2 bolts (in red rectangular) to adjust the position of the motor so you will have a better alignment.Decanter Centrifuge
2. We are having trouble locating a local supplier of SKF LGHP 2 grease for GN decanter centrifuge. Are there any other types of grease that are permitted to be used for the main bearings? Also, it seems like the greasing quantity is very high; about 270 grams for each bearing every 8 hours. The manual says that the grease amount should be 2/3 of the tank. Does this mean 2/3 of a 400 ml grease cartridge?
Some other grease can be used as long as they are suit for high speed working condition. Please DO make sure to use famous brands grease as the bearings are key components of the centrifuge.
Due to the high rotating speed of the bearing, the grease will lose a little every day, regularly lubricating helps to protect the SKF bearings. But I don’t think there is a large needing volume of the grease, only 25g and 86g for the small end and large end bearings, which is 111g for 2 bearings in every 8 hours. The reason amount is 1/3, which is also filled by our engineer when leave factory, you just need to add a little bit every day.

GN Mud Treating Systems for Eastern United States Customers

GN Solids Control designs and manufactures thousands of mud treating systems for global customers. GN Solids Control is especially good at manufacturing customized mud treating systems based on customers’ particular demands.
