A busy year always seems more quickly than usual, just like year 2017 for GN Solids Control. Since the decline of the crude oil prices from late Year 2014, it has been winter for all related industries and a tough time for all drilling companies. But, still, there are opportunities and gains for the ones who are ready to provide the clients with high quality products at reasonable prices.


When there are landmarks on each year, then the year will become remembered easily, as the year 2017 for GN Solids Control.Look back upon the past years from year 2017, GN has gained many achievements. As a privately owned company, they are not easy to achieve those goals.
Year 2017:
March, 2017 in Beijing, CIPPE, GN Solids Control showed a fully hydraulic decanter centrifuge of 14 inch diameter bowl at CIPPE Oil Show. But the glary of the fully hydraulic centrifuge was shadowed by the GNLW764-VFD Decanter centrifuge which has a 30 inch giant bowl and a large length diameter ratio up to 4.
May, 2017, GN new screen producing line was put into use, and all frame screens were upgraded with the composite material frame and SS316 mesh cloths. And full range of GN screen models has been tested to comply with API RP 13C, with large conductance and unblocked area. GN Screens are receiving perfect feedback from jobsite tests among all end users.
September, 2017, GN’s vacuum pumps are receiving good feedback from clients’ jobsites, and GN executed a tougher test in factory with low liquidate material on GN 1st generation vacuum pump. The result was satisfactory. It means, the problem for drilling cuttings transferring is solved, and the vacuum pump could handle material with solids content up to 80%.
We believe, GN will do better in Year 2018. We will see.

Each year, GN Solids Control produces around 150 sets of decanter centrifuges, a certain number among those are used for flocculation systems together with some chemical dosing systems. In some countries and regions, it is compulsive to have a set of flocculation unit and a decanter centrifuge alongside of the drilling rig, in order to treat the drilling fluids on time. And the after treated drilling fluids could flow back to the drilling system.

GN Standard Chemical Dosing Unit’s model is GNDW2000, which is designed in a standard 20ft container. It is easy for transportation and even suitable for hot or cold conditions. Inside the container, GNDW2000 chemical dosing system includes:

1. Three chamber polymer powder mixing unit, with a 2000L/hr treating capacity.
The three chamber tank has a total volume of 2000 liters. It is divided into 3 chambers for different functions: the first chamber is used for mixing the chemicals. After chemicals are added into the tank via a hopper, the small agitator is used to evenly mix the chemical into the water. Second chamber is for the polymer to dissolve. It need some time to dissolve before being added to the drilling mud. Normally it need 45 minutes. The third chamber is for storage. The ready dissolved fluid is in this chamber, waiting for pumped out by the dosing pump.
2. GNDW2000 Unit is using high standard material. The 3 chamber tank is made of stainless still. Besides being used as polymer dosing unit, it could be used for adjusting PH value also, by adding different components.
3. GN dewatering unit is a continuous working system with automatic functions. There are three level meters in this system for monitoring the levels and allow the system and operator to give suitable adjustment.

GN Solids Control is a famous brand who started from solids control equipment manufacturing, and now also professional in separation solution provider in nearly all fields including the oil gas drilling projects, HDD projects, TBM works, piling, water well drilling, drilling cuttings treatment, drilling fluids treatment and other industrial separation works.

GN EQUIPMENT WORKING VIDEOS
But still, among all the applications GN Solids Control’s products are used for, the traditional solids control system and equipment still occupies a large ratio among all GN’s products of each year, especially for the high standard clients, GN Solids Control is still their favorite and reliable supplier. For example, the Asian and Parcific market, like in Australia, New Zealand and India, where their standards are even higher than the USA and Europe.
In Australia, there are some special and difficult to reach standards, including the electric cable connections and layout, the tank surface treatment, the material choosing and even stair positioning. But GN Solids Control has rich experiences in working with Australia and New Zealand and also is well known by those clients. That’s why, during the past years, GN Solids Control has sold to Australia more than 30 sets of mud systems, not including the single equipment like decanter centrifuges and vertical cuttings dryers.

GN RECENT PROJECT NEWS
India is also a special market, India has talent management team and also brilliant engineers, they set up a high standard for their equipment, especially in oil and gas industries. For example, the shale shaker material, they always request the stainless steel as the material of the shaker frame. Although there are local solids control manufacturers in local India, still, clients are coming to GN for the suitable models and solutions. Even in Middle East, the management from big Middle East countries who are Indians prefer to choose GN Solids Control as manufacturer.

Recently, GN has produced for 2 different clients who worked for similar projects, with following equipment and solutions:
1. GN big bowl 22 inch diameter decanter centrifuges.
2. GN chemical dosing unit
3. GN standard containers.

GN CONTAINERIZED CENTRIFUGE AND DEWATERING

GN has been providing this design for many years, and the technology is quite mature:
1. GNDU2000 Chemical dosing unit. GN has been providing the chemical dosing unit or so called the dewatering unit for many years, since some of GN clients are using GN centrifuges as dewatering centrifuges and prefer GN to make compact design for them. A chemical dosing unit is used to treat the material by some chemical methods, for example, to add some material to reduce the viscosity of material, or to flocculate the extra fine particles into larger ones, which are suitable for centrifuge use.
2. GNLW553C-VFD decanter centrifuge is a big bowl decanter centrifuge with a treating capacity up t to 90 cbm per hour, and the rotating speed could reach 3000 rpm. It is quite suitable for drilling liquid management, especially being used together with chemical dosing system. Normally, the centrifuge treating capacity for material after flocculation would be greatly reduced, that’s why a big bowl centrifuge with a large treating capacity is always used for this application.
3. 20 ft containers for housing the centrifuge and chemical dosing system, which is quite popular design. For one thing, it is more convenient and easy to transport the system when the main equipment are in standard containers. Secondly, the containers give a shield to the equipment, providing a suitable temperature and clean condition. Thirdly, the 2 sets of 20 ft containers could be put one under another, in this way, less room to be occupied.
In this design, GN engineers designed the round shaped ladders for the upper located container with the big bowl decanter centrifuge, when transporting, the ladder could be put into the container.

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.

Ever since GN Solids Control started manufacturing for solids control equipment, in order to control the screen quality for GN’s own brand shakers, GN has invested in a screen factory. As the rapid development of GN Solids Control, just in early year 2017, GN Solids Control has invested in a new screen producing line with automatic screen producing facilities and upgraded all screen models for GN shakers.

Previously, nearly all frame screens are made of steel frames, and most producing procedures are manual. But with the new screen producing line, following improvements were achieved:
1. For welding the screen frames, GN is using an automatic welding robot to ensure the precise positioning of every point.
2. GN is choosing the highest quality fiber glass as the plastic component in order to ensure the high temperature resistance of screens.
3. Stainless steel material as screen mesh for longer screen service life.
4. Ideal screen mesh configurations as per API RP 13C standard, and higher conductance at same API number.

As both the producing cost and material cost are higher for composite material frames than steel frame screens, why GN and GN clients prefer composite material frame ones?
1. The composite material frame screens could be storage for longer time than the steel frame ones. Per GN experiences, after storage for 2 years, most of steel frame screens would lose much characters, but composite material frame ones could be storage at least 5 years without losing any performance.
2. Comparing with steel frame screens, the composite material frame occupies smaller screen area, so the useful area is larger, by more than 10%.
3. Composite material frame screens are repairable. With GN Special made screen plugs, the composite material frame screens could be underuse with up to 10% surface broken.

Now GN is holding big promotion on screens, pls contact GN for more information.
