Recently, a full set of vertical cuttings dryer system is finished and under running testing. After running test in the factory, the system will be packed and shipped to a Chinese domestic market to treat oil base mud and cuttings.

GN Solids Control is specialized in drilling waste management equipment. All GN drilling waste management equipment are specially design with higher material standard for anti-abrasive and reliable servicers. GN cost higher than other solids control companies, so GN equipment price is higher than other Chinese suppliers, who mostly used the same standard solids control equipment for waste management.

The system the client choosing is GN portable1-skid cuttings drying system for oil based mud and cuttings. The system can be used on rig site or off rig site.

GN 1-skid vertical cuttings dryer system includes below processing units:
1) A set of vertical cuttings dryer GNCD930C is used to dry the cuttings. The vertical cuttings dryer is complete with flush screw pump and telescopic skid. After the VG dryer separation, the oil on cuttings can be reduced to 5% less.
2) A set of decanter centrifuge unit. It is complete with screw feeding pump and a small holding tank. The decanter centrifuge can remove ultrafine solids less than 2 ~ 5 microns.

The flow line processing line of the vertical cuttings dryer unit is normally as below:
1) While the cuttings drying system used at rig site, screw conveyors are used under shale shakers and mud cleaner to collect drill cuttings and transfer to vertical cuttings dryer.
2) After separated by the vertical cuttings dryer, the dryer solids discharged fall down to an inclined screw conveyor and transferred out. The recovered drilling fluids is too heavy to be reused for drilling, so decanter centrifuge is used after it to remove the ultrafine solids and reduce the mud weight.

GN Solids Control oil sludge treatment system is mainly used to recover valuable oil in the sludge, and the sludge treatment process can generate greater economic benefits. At the same time, the emission of harmful substances has been greatly reduced. Recently, GN Solid Control completed the manufacture of a full set sludge treatment system. The system is currently undergoing final assembly and factory testing and will be shipped to a waste management customer in Asia.

The working principle of the sludge treatment system is oil, water and solids three-phase separation. Therefore, GN Solids Control sludge treatment system is mainly composed of three parts: coarse particle separation unit, fine particle separation unit and oil-water separation unit.
The coarse shaker screen is used to remove large particulate solids from the sludge. Before feeding the shale shaker, the operator needs to dilute the sludge with solids content less than 20% for pump transfer.

GN Solids Control oily sludge treatment system has a sludge vacuum pump, which is ideal for sludge transport. The shale shaker is located on a canister that collects liquid through the vibrating screen. A mud agitator is installed in the tank to prevent solid precipitation.

A decanter centrifuge is used for fine particle separation. GN Solid Control is capable of providing 9 to 30 inch decanter centrifuges. The feed pump draws sludge from the tank under the shaker screen and feeds it to the centrifuge. During the separation process, the fine solids are removed, and the oil-water mixture is discharged to further separate the three phases.

GN Solid Control uses a disc centrifuge for oil, water and very little solids separation. Disc centrifuges can operate at higher speeds, allowing oil and water to be separated. Depending on the customer’s working conditions and use, a chemical dosing device is required to help remove oil from the solids.
According to different material handling requirements, GN Solid Control has designed three types of sludge treatment systems: GNOST-01A, GNOST-05A and GNOST-15A. For more information on sludge handling systems, please feel free to contact GN Solids Control.

The helical bevel gear reducer mud agitator is a popular design for drilling mud recycling and mixing systems. It is a kind of heavy duty mud agitator. The mud agitator can be used for the shale shaker tanks, mud mixing tanks, mud storage tanks, intermediate tanks, suctions tanks, pill tanks, etc…

The helical bevel mud agitator adapts Gleason quasi-hyperbolic gear reducer. The helical bevel gear reducer is equipped with hard tooth surface. It is large loading capacity, low noise, long service life and high efficiency.

There is another kind of gearbox for agitators: it is worn and gear agitator. Compared with worn and gear reducer mud agitator, the helical bevel reducer agitator is more heavy duty and reliable, its torque is nearly double than the worn and gear agitator, so the helical bevel agitator can adapts a stronger performance with a smaller motor to reduce power. But the cost of helical bevel agitator is much higher than the worm and gear reducer agitator.

So when you compare mud agitator quotation from different suppliers, please specially payment attention of the technical description on the reducer types.

GN Solids Control can offer both helical bevel mud agitator and worn and gearbox mud agitator with different motor powers. Clients can choose the suitable type per his mud condition and the budget of the project. Or clients can contact GN sales manager to recommend you the suitable type for his project.
