Decanter centrifuge is the most important equipment for drilling waste management field. It can be used for waste water treatment, slurry separation, oily sludge separation, etc…
Application of decanter centrifuge for waste management field
1) Decanter centrifuge can be used together with high G shale shaker to treat water base mud drilling cuttings. Water base drilling cuttings is treated by high G shale shaker, after shaker, goes to decanter centrifuge to separate the fine solids.
2) Decanter centrifuge can be used together with vertical cuttings dryer to treat oil base mud and synthetic based mud drilling cuttings.
Oil base mud and synthetic based mud drilling cuttings from tank bottom, shale shaker, desander desilter or offshore rig, are treated by vertical cuttings dryer first, after vertical cuttings dryer, goes to decanter centrifuge to separate the fine solids.
There are so many companies declared for decanter centrifuge manufacturing, but do you know how to choose the right decanter centrifuge and optimize the centrifuge performance?
Firstly, the reliable brand should be chose depends on the applications. For centrifuge brand section, you should check with the supplier, if their centrifuge have been used for the similar applications and the performance, or at least their reference on waste management field.
If their centrifuge mainly used for solids control mud system, most probably, it will not suits for waste management. As for waste management, the material is more critical, high solids content and high abrasion. If request the centrifuge should be very reliable on design (feeding port, solids discharge port, screw protection, control panel, etc…) and excellent on material choose.
Secondly, choose a suitable model per your application: high speed / high G force / big bowl / super high speed… There are so many design. You should choose the most suitable model per your material condition and the performance you want to get.
For example, if you want a normal system to do service, you want the system can treat more kinds of drilling cuttings, OBM, SBM, WBM, GNLW363CG-VFD decanter centrifuge should be suitable. It is a 14 in centrifuge with adjustable speed for different application.
Then, even for the same centrifuge model, the different fluids level height, bowl speed, conveyor speed, feeding capacity, jobsite layout, feeding type will affect the performance greatly. That is the reason why centrifuge request a professional operator together. Decanter centrifuge has high request on operators’ capability than solids control system. Many jobsite, they have good machine, but do not equipped with professional operator, so also problems.
GN Solids Control as China top manufacturer on decanter centrifuge, welcome you inquire more questions on centrifuge, and visit GN for the training of centrifuge.

Drilling waste management equipment for 2015 OTC oil show
1) 22 inch Big bowl decanter centrifuge, model GNLW553C-VFD
The centrifuge model is made per international high standard. It is a big bowl centrifuge specially designed for drilling waste management. The centrifuge is with a big bowl 22 inch dia. and 71 inch in length. As drilling waste management request higher standard equipment. With the specially design for drilling waste management field, this centrifuge performance excellent as well in solids control system.
Besides used for drilling waste management, GNLW553C-VFD is widely used for mud solids control system in rig site, especially in U.S and European, where the rig site do not use desander and desitler. All materials comes from shale shaker will enter into decanter centrifuge for treatment. Big bowl centrifuge with big capacity is suitable and necessary in these rig sites.
2) 14 inch high speed centrifuge, model GNLW363C-VFD
It is the most normal size decanter centrifuge. There are so many companies said they makes 14 inch decanter centrifuge. But it is not all of them can be used for drilling waste management. GN patent design with its excellent standard material makes its centrifuges has reliable performance while treating drilling cuttings.
3) Vertical cuttings dryer, model GNCD930D
It is the latest design vertical cuttings dryer from GN Solids Control. With good performance and feedback from worldwide jobsite. It is the most proper choice to for oil based cuttings.
Now good news is that, all above equipment is for sale. If you make orders, after the show, the ready equipment will be sent to you directly from GN Solids America Houston warehouse.

At the beginning of 2015, GN get an repeat order from one of our valuable clients with 32 units of drilling mud decanter centrifuge with 40 units of screw pumps, we shipped them in 2 batches, the first batch 16 units centrifuges are shipped before Chinese traditional Spring Festival, and the rest 16 units are shipped after we come back from the long holiday.
The centrifuge is utilized for fine solids separation at high speed and barite recovery with low speed, there are 2 ways to get them used in different speed:
1 equipped with variable frequency drive control panel, it can adjust from 0 to 3200rpm. It is a easy way for operator, but the VFD control panel cost a lot.
2 equipped with different size pulleys, when you need to use it for different speed, you can just replace the pulley, it is a economic way.
Not only for Solids Control,these decanter centrifuges can also be used for drilling cuttings treatment system, dewatering system, both for oil based drilling mud and water based drilling fluids. To check the performance of GN decanter centrifuge applied for water based drilling mud, pls check the video here: http://www.gnsolidscontrol.com/video/water-based-mud-decanter-centrifuge-argentina
To check the performance of GN centrifuge used for dewatering system, pls check the video here:
http://www.gnsolidscontrol.com/video/gn-solids-control-drilling-mud-dewatering-system-working-video
GN C version decanter centrifuge is the most advanced technology centrifuge after years of improvements, we make such improvements according to the user’s feedback and suggestion, the most obvious advantage of C version decanter centrifuge compared with B version is the screw and bowl design changes. We will show the updated version decanter centrifuge both at CIPPE 2015 oil show in Beijing, China and OTC 2015 ( world’s largest and most professional oil show) in Houston, TX, Pls contact our sales to make an appointment and visit our factory.

GN Solids Control is a specialized manufacturer for the drilling mud solids control and drilling waste cuttings equipment. The shale shaker is one of GN’s main products. For this main product, at this time all the model GN’s provided is the linear motion vibration mode. As per the requirement coming from different industry and the customer’s preference, GN’s shale shaker is classified by the treating capacity and application.
GN’s shale shaker is classified as 200GPM, 500GPM and 600GPM. The smallest model is always be used in the compact system for the job site with limited location area. GN’s 600GPM model could be used in both the common solids control and waste management system. When talking about the slurry feeding type of GN high G force drying shaker, there are 3 types used for different application. The 3 types of the feeder box are the top located design; back located design and hopper designed. For the top located design feeder box, the shale shaker is often proposed to use in the mud recycling system for the HDD projects. As the mud tank in HDD are always narrow, so there is no enough space of the tank surface to locate the shale shaker. In HDD project, the drilling mud are always fed to the shale shaker through the pump, the drilling mud come to the screen with very low pressure, so the drilling mud would come to the screen directly from the top located feeder box. While in the oil drilling projects, the drilling mud always comes out from the drilling hole with high pressure. Thus there will be a buffer box to reduce the high pressure of the drilling mud, the feeder box is designed like an “nâ€, and the drilling fluids need overflow into the shaker deck.
For the hopper design feeder box, it is specially used for drilling waste cuttings dryer system. As the waste cuttings are always very thick, and the fluidity is not as good as the drilling fluids. When delivered to the drying shaker by the screw conveyor, the waste cuttings have to get into the shaker via a large opening feeder box. For this type hopper, it is easy to let the cuttings get in and performance would be very well.
