The augers are also called the screw conveyors, they are used in GN drilling cuttings waste management system as a matching equipment alongside with vertical cuttings dryers and decanter centrifuges.
In some rig sites, it is requested by the law that for each drilling rig, there must be a set of drilling cuttings waste management system, and totally in the rig site, there should be at least 2 augers: first one is below the discharge chutes of shale shakers, desander cones and desilter cones, that is used to collect the cuttings. Second one is used as a sloping angle to transfer the cuttings from the first one to the vertical cuttings dryer. In a word, the augers could be positioned sloping or horizontal for different destinations. In a word, GNSC screw conveyors could work in a group or singly, and they could be used for mixing, allocating, dewatering, discharging and etc.

gn augers

As an essential part of a waste management system, in order to well match the other equipment and easy for transportation and locating, all GN screw conveyor models are designed in same length sections, each of 12 ft. And they are of different diameters for providing different transferring capacities. There are 10 inch diameters, 12 inch diameters, 14 inch diameters and 16 inch diameters. In this condition, most of spare parts are interchangeable, which reduced the spare parts cost and enhanced the convenience for the end users. GNSC series screw conveyors are using the wear proof material for a obviously longer service life than its peers’.
GNSC series screw conveyors are not only used in the drilling cuttings waste management systems, they are also quite widely used in construction, chemical, power plants, coal mining and other industries. In some customized conditions, GN could also add the insolation layer to the augers to keep the temperature at a certain range.

After being developed from a solids control manufacturer and focusing on only high quality product manufacturing, GN Solids Control has become more like a separation professional and their salesroom is more and more occupied by some more widely used separation equipment which are suitable for more industries covering the oil and gas solids control, waste management, oily sludge separation, mining, TBM, HDD, food industry and also waste water separation.
Decanter centrifuge is quite an important equipment for the separation work. For example, a middle speed centrifuge could separate out particles from 5 to 8 microns like the expensive barite in the drilling mud, while a high speed decanter centrifuge could separate out the cuttings from 2 to 5 microns. With help of a chemical dosing system, the even smaller particles could be separated out together with a flocculation unit.

GN Hydraulic centrifuge

Comparing with other separation equipment, a centrifuge has many advantages like continuous operation, easy for maintenance and requesting less chemical components to be invited. GN has a full range of decanter centrifuges with different sizes, including 9 inch diameter bowl, with length-diameter ratio of 3 and 4 ( long or longer), 14 inch diameter bowl, 18 inch diameter bowl and 22 inch ones, they all have models of 3 or 4 as length-diameter ratios. And GN also has 30 inch diameter bowl decanter centrifuge, with a bowl length- diameter up to 4.
Among all those models, the 14 inch bowl models are most popular and economic, which are suitable for many applications. And for this model, GN has also hydraulic control model for option. Recently, one set of hydraulic decanter centrifuge will be shipped to an oversea customer, and it will be used for a big oil drilling company. Meanwhile, some more decanter centrifuges are being built for a safe stock and delivery to clients.

Just not long ago, GN Solids Control who owns are quite professional R&D team in solids control industry, has developed and got patented of a series of ViST Vacuum Shakers. It would be a new page of solids control industry, because the ViST vacuum shaker will greatly reduce the drilling cutting proportion and enhance the treating performance during solids control.
Here is the working video of GN ViST Vacuum Shaker.
Here are the main parameters of GN ViST vacuum shaker:
1. Pressure of air source: 0.7-1.0 Mpa, equal to 100 to 150 psi
2. Air consumption: 4.5 cbm/min, equal to 160CFM
3. Matching shaker quantity: 2 or 3 sets
4. Suitable mud: all types of mud including SBM, OBM and WBM
5. Mud recycling ratio: 30 to 50 percentage
6. Mud temperature from minus 15 degrees to 85 degrees centigrade
7. Control type: automatic pneumatic control
8. No electrical power needed

Features and advantages of GN ViST Vacuum Shaker:
1. Wide application for all mud type including WBM, OBM and SBM.
2. It is suitable for both land rigs and offshore rigs, to enhance the working efficiency of the shake shakers, to recycle the drilling fluid to the most while discharge the cuttings to the least.
3. A ViST shaker could replace the drying shaker at a lower cost comparing with drying shaker.
4. Small footprint, even no extra space needed when added onto existing shakers, which is very important for offshore conditions.
5. Easy for installation for both GN’s own shakers and other brands’ shakers.
6. By using a ViST devise, the solids control shale shaker can use shaker screens with larger API number without leaking, in order to enhance the treating efficiency.
7. By discharging dryer cuttings, it would be easier for transport or discharge the drilling cuttings.
8. Easy to be operated by one operator only.

In the past CIPPE 2018 international oil exhibition which was held in Beijing last week, GN brought out some new products including a compact oily sludge separation unit. And this newly built oily sludge separation unit attracted many visitors.

GN AT CIPPE 2018

GN AT CIPPE 2018

GN Solids Control, ever since its establishment, always set its goal as China Intelligence. Each year, GN Solids Control’s R&D team make into reality some new designs and those are always proven to be practical and efficient. For example, in last year’s CIPPE, GN took to exhibition a 30 inch bowl decanter centrifuge and a fully hydraulic decanter centrifuge, and in this year, the 30 inch decanter centrifuge was soon put into use in a TBM project and was proved to be a success and good comments from client. This year, the new equipment GN brought to CIPPE 2018 including following:
1. Mini oily sludge separation system, including pre-heating step, chemical dosing step, shaker for separating the large particles, decanter centrifuge for separating our the fine particles and a three phase centrifuge for further separating the oil, water and solids. After those treatments, the OOC could reach 2%, solids and water in oil is less than 3% and oil in water is between 50-100 ppm. By using the pipelines and valves, the chemical could be dosed both before and after shaker, and the light material before entering the decanter centrifuge could by pass the centrifuge to reduce the burden of centrifuge.
2. Vacuum pump. Vacuum pump is not exactly a new product of the year, cause last year, GN already put it into use. But this year, GN improved it and gave it to jobsite for test. It is excellent. It could transfer even solids, with a small character to flow. That’s why it is called a solids pump with wide applications.
3. GN full range of shaker screens for GN own brand shakers and other famous brands. For the frame screens, GN already upgraded them into composite material frame ones, for the hook ones, GN is upgrading them now.
4. GN core products including shale shaker, vertical cuttings dryer and decanter centrifuges of big bowl and medium size.

Drilling waste management is one of the core system GN Solids Control produces, it includes the drilling cuttings separation and also the drilling fluids separation. Dewatering unit, which is also called chemical dosing unit is one of the important components of the drilling fluid treatment systems.

In some countries and regions, it is a must that a drilling rig must be accompanied with a dewatering unit and a dewatering centrifuge, for one thing, more drilling mud could be recycled, which means to reduce the cost and save money. For another thing, it is reducing the harmful components to be discharged to the soil or environment, it helps to protect the surroundings.

GN Solids Control has been providing the dewatering unit for many years, and the dewatering unit now are more and more widely used for different applications, such as:

1. Oil and gas drilling fluids separation. After being used for a certain time, there are more and more extra fine particles in the drilling fluids, even too fine to be separated out by a centrifuge. By adding some chemicals into the fluid, the extra fine particles flocculate into bigger ones to be separated out by centrifuge.

2. In TBM, Piling and other projects, when the slurry is of higher viscosity or need to be added with some chemicals, the dewatering unit is playing an important role, just as shown in the picture, the treatment was successful.

3. In oily sludge separation projects, the added chemicals helps to separate the oil from the cuttings, which greatly increase the efficiency of centrifuge and oil water separator.

GNLW Series decanter centrifuge, especially GNLW363G-VFD, GNLW553-VFD centrifuges are always ideal choice for working together with dewatering unit. Besides those models, GN also has centrifuges with bigger length-diameter ratio for clearer separation.
