GN 3 Phase Decanter Centrifuge for Waste Oil Recovery

Keeping improving is the major feature of GN Solids Control, and this could be proved by the continuously issued new products in GN’s line sheet. Just shortly before, GN published the 3 phase decanter centrifuge on the official website to tell customers that GN is able to provide this type decanter centrifuge which is very popularly used for recovering the waste oil.

The slurry treated by the 3 phase decanter centrifuge is consisting of two kinds of immiscible liquid, always water and oil, and solid. The 3 phases need have different density so that the centrifuge could separate much easier, as all the horizontal decanter centrifuges are separating the phases by centrifugal force.

GN’s 3 phase decanter centrifuge structure is not big different with 2 phase model. The difference is how the liquids discharged out of the centrifuge. The solids in the slurry should have much higher density than the liquid, and then the solids could be easily separated out, which will increase the efficiency of the separation process. Higher density liquid will be discharged out under the pressure, while the light liquid will flow out from the liquid discharge ports at the bowl end face.

3 phase decanter centrifuge is mainly used in separation of oil sludge containing oil from refineries. Oil refineries have many holding tanks for oil need cleaned regularly, always the operator will used high pressure water to flush the bottom of the mud tank, and this type mixed slurry is the main source of the material treated by the 3 phase decanter centrifuge. Some other industries like food industry, edible oil production, biofuel production etc will also widely use 3 phase decanter centrifuge.

GN solids control now could provide the 3 phase centrifuge with bowl size of 14 inch, 18 inch and 22 inch. Any of your inquiry about other equipments such as shale shaker, mud agitator, mud gas separator , shear pump etc. is welcomed.

HDD Mud Recycling System with Decanter Centrifuge

HDD drilling is short for horizontal directional drilling project, it is widely used for the pipeline work for the oil and gas transporting and etc. Normally, the drilling mud recycled from the HDD machine is to be reserved in a mud pit and the mud cleaning system, which is used to treat the mud to be next time use, treats the drilling mud from the pit and storage the well done mud in the tanks.

Equipment needed for the HDD mud recycling system:

In a traditional HDD mud recycling system, there arenormally 3 phase of separation equipmentincluding shale shaker, desander cones, desilter cones and mud mixing unit for adding new chemicals into the drilling mud, normally 2 jet mixing hoppers and mixing pumps. But now, as the environment demands and the cost pressure for the contractors are becoming more and more important, a lot of HDD contractors are taking decanter centrifuge into consideration in order to get better separation result and lower the mud weight.

What is the main function of the decanter centrifuge used for the HDD drilling mud system?

1.       The centrifuge helps to minimize the negative effect on the environment.

2.       The centrifuge helps to reduce the weight of mud.

3.       Centrifuge helps to lower down the total cost on mud.

GNLW452C or GNLW452C-VFD is a very suitable model of decanter centrifuge to be used for the HDD mud recycling system. It is big bowl centrifuge of 18 inch bowl diameter and the speed of 1800 RPM is efficient for the HDD works, in China, the largest HDD contractor CPP, always use GNLW452 in their mud cleaning systems.

The centrifuge feed pump could transfer the mud from the storage tank to the centrifuge and after the separation, the mud could directly fall back to the same tank, cycling like this helps to reduce the mud weight. Or, there could be another storage tank to collect the drilling fluid from the centrifuge.

Welcome to contact GN for more suggestion and learn more information about other equipment such as mud gas separator, shear pump, mud mixing system and drilling waste management equipment..

4-tank mud system for 750hp drilling computer

GN Solids Control is really a worldwide famous brand of mud solids control system, drilling waste management system, and also replacement shaker screens.

Soon, GN Solids Control Cina factory finished a mud system for a domestic job. It is a 4-tank mud system for 750hp drilling rigs.
1) The 4 mud tanks of the 750hp drilling mud system are the same sizing with 40ft container. And also the tanks are equipped with 3-runner oilfield skid. The oilfield skid is with 250mm at each tank ends. It makes the aquariums easy to movement at jobsites.
2) GN Solids Control equips 2 sets Solids control linear motion shale shaker separator for the system. The system is equipped with only two each 3-panel shale shaker, model GNZS703E. It is the hottest shaker models for coal and oil mud system from GN Solids Control.

3) Within this system, the clients pick 1 desander separator plus a desiler separator.
The desander model is GNZJ752-2S. Its equipped with 2 ea 10’’ desander cone. Each 10’’ desander cone is with greatest extent. 120 m3/h (528GPM) managing capacity.
The desilter cone model is GNZJ752-12N. It truly is equipped with 12 ea 4’’ desilter cone. Each 4’’ desilter cone is with utmost. 20 m3/h (88GPM) managing capacity. For totally 16 ea 4’’ desilter cone, the desilter handling ability can reach to 240m3/h (1056GPM).
4) The 4-tank mud system is equipped with some sort of middle speed decanter centrifuge to recovery the barite and reduces the mud weight. The centrifuge product is GNLW452. It is a the majority of cost-effective big bowl decanter centrifuge widely used in solids control mud systems intended for oil rigs.
5) As well as many mud agitators, mud guns, lights, and sends for the system.
6) This kind of clients choose a separate plane mud mixing system. Typically the jet mud mixing hopper and mixing pump along with control panel are all attached in a separate oil discipline design skid. It is easy to shift it and work to several mud tank systems.

The Primary Safe Unit ---- Mud Gas Separator

We're able to begin to see the mud gas separating set up in many drilling rig jobsite. Regarding to complicated geologic atmosphere of drilling site, mud gas separator can be used for separating the hazardous gas in the drilling liquids. Not just mud gas separator can be used for oil & gas drilling site, but it is also requested the deep mining drilling jobsite.

GN mud gas separator’s working principle

The drilling liquids/mud from lower hole adopts mud gas separator (poor boy degasser).Because of the gravity pressure; the mud drops lower around the 1000mm diameter vessel of poor boy degasser. Mud collides on buffer plate of pipe therefore the harmful gas is going to be relieved in the drilling liquids. Clearly, gas flows to the peak of 8 inch vent line that is associated with the flare igniter to lose out. Normally, flare ignition system is about 160 foot from the poor boy degasser to make sure the safe distance burning. Meanwhile, the mud would go lower and gathered at the end of mud gas separator, and subsequently flow towards the in to the solids control system including shale shaker, desander, desilter and decanter centrifuge etc

Why we decide GN mud gas separator?
