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.

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.

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.

2. GN shear pump. Shear pump is not so commonly used as centrifugal pump. They are only used for shearing some special chemicals which are needed for large horsepower oil and gas drilling rigs.
3. Submersible Slurry pump. Submersible slurry pump’s applications in GN solids’ mud system and mud units are mainly those two: one is for centrifuge feeding in solids control systems like for the barite recovery and extra fine particle separation, or for the HDD mud recycling units, it is the second to none choice for transfer slurry from the mud pit to the mud system.
4. Vacuum pump. GN series vacuum pumps are the newest member among GN pumps. But it gained highest attention ever since its birth. Comparing with other pumps, the most obvious difference is that it has no motor. It is fully air driven and has less limitation for the solids size. In practice, it could handle material with particle size only a bit smaller than it’s pipeline diameter.
