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

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.

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.

GN Solids Control is one of the leading brands for solids control and waste management system, and second to none ranks among Chinese manufacturers in this industry. A lot of worldwide famous oil companies and oil drilling companies are using GN equipment and comprehensive solutions, including SINOPEC, CNPC and COSL. Recently, GN delivered main equipment for 2 sets of drilling cuttings waste management systems for CNPC.

GN BIG BOWL CENTRIFUGE FOR CNPC

Drilling cuttings are solids discharge from the drilling rig solids controls system, from the shakers, desander and desilters. After the solids control system’s first 3 phases separating, the drilling fluids are returned back to the system without the solids particle. But the separated-out particles are still too wet. For one thing, it is a waste for valuable drilling fluid. Secondly, it could damage to the environment if disposed directly. That’s why it is not only necessary but also mandatory to do some further treatment for the drilling cuttings.
GN Solids Control has zero discharge solutions for both WBM and OBM. And this order, combining the vertical cuttings dryer and decanter centrifuge, is for the oil based mud. A vertical cuttings dryer is specially designed for the oil based mud separation. GNCD930 series vertical cuttings dryers could dry the drilling cuttings to reach OOC value to 5%. The vertical cuttings dryer is running as the drying step of a washing machine. The vertical cuttings dryer is equipped with a screen basket with certain mesh number. Fluids pass the mesh and collected, while cuttings are stopped by mesh and falls down.
GNLW series decanter centrifuges with VFD control panels are used after the vertical cuttings dryer to remove the particles from 2 to 5 microns from the liquid. Most common model is GNLW363CG-VFD, a medium sized centrifuge with a high rotating speed. But for bigger treating capacity, GN has GNLW453C-VFD and GNLW553-VFD available, both of high rotating speed while bowl sizes are respectively 18 inch and 22 inch. In this project, clients chose GNLW453C-VFD.
Pls contact GN for more information.

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.
