Centrifuges are quite popular in separation industries, in oil and gas solids control, in drilling cuttings waste management, and in oily sludge separation projects. It is perfect solution for separating out particles from 2 microns to 5 microns. The centrifuges are playing more and more important role. But still, it is more difficult to operate the centrifuge well and let the centrifuge to work more efficiently.

GN HIGH SPEED CENTRIFUGE WITH SKID

GN HIGH SPEED CENTRIFUGE WITH SKID

There are some suggestions to help improving the centrifuges’ performance:
1. Before using the decanter centrifuge, make sure the material which enters the centrifuge are not so big for the centrifuges, in order to avoid blocking of centrifuges. For instance, a high speed centrifuge is capable to separate out particles from 2 microns to 5 microns. In practice, particles no larger than 2mm could enter the centrifuges. So it is suggested to use a shaker unit before the centrifuge.
2. How about when the particles are too small? When there are so many extra fine particles, it would be difficult for the centrifuge to separate the particles out. In this case, a chemical dosing unit is invited before the centrifuge. By adding flocculant into the material, the extra particles flocculate into bigger ones in order to be separated by centrifuge.
3. If the material is of too high viscosity, some polymers fed by the chemical dosing unit into the material, to lower down the viscosity. Then the separation result would be much enhanced.
4. Confirm the material content before choosing a suitable bowl rotating speed and a suitable differential speed. The material content information includes: solids content percentage, the distribution of each particle size, and etc. Such information helps the operator to adjust the centrifuge parameters.
GN Solids Control is quite professional in centrifuge design and manufacturing, GN centrifuge sizes range from 9 inch bowl to 30 inch bowl. Pls contact GN for consultancy.

Although during the past 2 years, the waste management and environment protection proposals GN produced are occupying larger and larger share of all GN products, the traditional application GN Solids Control has been professional in has not lost it’s advantages. Recently, just when the oil and gas industry is picking up, GN’s international market is coming up again and a UAE client just purchased a 350GMP mud recycling system from GN Solids Control.
GNMS series mud recycling systems are one of the best seller products among all GN products, during those years, especially the 500 GPM mud recycling systems. In some jobsite, the 350 GPM mud system could serve as 500GPM mud recycling system, too.
This mud recycling system is combined by 2 phase separation equipment, plus a mixing unit. Depending on the limited space request on client’s jobsite, and also taking into consideration the transportation, the desander cones are not used in this system. For the first 2 level of separation, GN designed a double deck shaker, the lower shaker deck is served as shale shaker, with coarse meshes, .while the upper deck shaker is under the desilter cones, playing as the drying shaker for desilters.

On the other side of the tank, there is a mixing hopper, which is a common component of a mud recycling system for HDD projects. It is used to add and mix some necessary chemicals into the drilling mud.
Each year, GN Solids Control produces tens of mud recycling unit to the non-oil and gas industries, mostly for HDD, CBM, Water well drilling, TBM and Piling. All such mud systems could be grouped into 2:
1. Self-contained mud recycling systems with larger mud capacity and a mixing unit. Those systems, in application, are mostly used for HDD, CBM and etc. Normally, clients use a slurry pump to transfer mud from mud pit to this system and use mud pumps to suck out mud from the system.
2. Compact mud unit, without a mixing unit, mostly used for piling and TBM.

The service companies or project contractors are always very strict on choosing equipment manufacturers, because a good manufacturer is not only about the image and reputation, the more important thing is, the good performance of the equipment. Like for the oil and gas drilling, working on the rig means continuously operating and any unexpected failure comes at big cost.
In many projects which are in need of separation works, the shale shakers play a very important role. For example, in oil and gas drilling solids control projects, the shale shaker take over more than half of separating work, and in HDD or TBM projects, a shaker is always the first or even only separation step, even in drilling cuttings waste management projects, a high-G shaker with a 8.0G force are head in the queue.

GN NEW ORDER FOR SOLIDS CONTROL EQUIPMENT

GNZJ series shale shakers have following features:
1. High G force to ensure a good performance and good separation results. With Italy brand Oli as professional vibrating motors, GN shale shakers could reach a G force up to 7.5, and according to the jobsite condition, this G force is adjustable.
2. A strong structure of shaker deck made of stainless steel, instead of normal steel. Only a strong structure could endure the high G force vibration. That’s why GN shale shakers have a longer service life.
3. API RP 13C shaker screens with composite material frame. GN now make all its frame screens with composite material frames, it has a longer service life than steel frame ones, and the conductance is much larger. With same screen area, the unblocked area is much larger than steel frame ones.
Those above mentioned are only several features and advantages of GN shale shaker and shaker screens, since space here is limited, if you need more information about GN company and products, welcome to visit our website or contact us by email, telephone or fax directly.

In most of countries in the world, environment protection is very important for all industries with very strict laws. For the drilling projects, the separation standard is evens more. That’s why, GN became one of the most well-known brands during past years and its adjacent countries for the ideal separation solutions in oil and gas drilling industries and other drilling projects like HDD, TBM and etc, and even for the construction works.

Per experiences and calculated data, the drilling liquid occupies in any well drilling is between 4 percentage to 10 percentages, no matter in onshore drillings or offshore drillings. Considering its effects on the drilling operation performance, which occupies nearly 50 percentages, the drilling fluid is quite vital to the drilling.

GN Waste Management Equipment

That’s why, a professional drilling manager has to have a professional team for the drilling mud services, or find a qualified drilling fluid service company. In practice, drilling companies or drilling contractors always focus on drilling work, and employing a subcontractor for the solids control system. Each drilling rig has eight systems connected to each other, among which, the solids control system is comparably independent. An expertized drilling fluid company has the right personnel and suitable equipment, and more important, they know how to treat the fluid well.

A professional oil service companies provide following services:
1. Solids control equipment and services. The solids control systems help to treat the drilling fluid directly from the well mouth. It contains three or four phases for separation, including the shale shaker as the first phase, the desander cones as the second phase, the desilter cones as the third. Some include the decanter centrifuge as the forth one. In most solids control systems, there are mixing unit for adding more chemicals into the fluid when necessary.
2. Drilling cuttings waste management systems, in some countries, this part is also regarded as a part of solids control, because this is also for treating the solids from the drilling fluid. Those systems always contains the vertical cuttings dryer, the high G drying shaker and the decanter centrifuge.
3. Drilling fluid waste management, it is the further treatment for the drilling fluid. As the fluid has been used for a long time, this system uses some chemicals to flocculate the extra fine particles into larger ones before being separated out by a decanter centrifuge.
As one of the leading manufacturers of solids control and waste management, GN Solids Control has been providing lots of oil service companies in the world for all above mentioned systems and equipment. For more information or a formal quotation, welcome to contact GN directly.
