This week, GN Solid Control completed the manufacture of two sets of vertical cuttings drying system. The cuttings drying system will soon be shipped to customers in China domestic market.

Vertical cuttings drying system is mostly used to treat oil base mud and oil base mud drilling cuttings. The whole system is mainly composed of cuttings drying module and fine particle removal module. Each module has a key core separation device to treat the drill cuttings.

1) Vertical Cuttings drying module

Vertical cuttings dryer is the key equipment of cuttings drying module. Usually, drill cuttings are fed into the drill cuttings drying device by vacuum pump or screw conveyer. Under the action of centrifugal force, the oil will be separated from the drilling cuttings, goes through the screen opening of screen basket, and enter the collecting tank. Regarding the opening sizes of the drying screen, GN Solids Control offers 3 sizes for option: 250 microns, 350 misrcons and 500 microns, which can be used to dry cuttings of different sizes. GN Solids Control advanced design vertical cuttings dryer is equipped with a flushing system and an air knife system for cleaning the mud collecting trough and screen to avoid blockage.

2) Fine Particle Removal Module
High speed decanter centrifuge is the key equipment of this module. The liquid effluent discharged by the dryer will be pumped to a high speed decanter centrifuge for further treatment to remove fine particles in drilling fluid. In order to ensure the performance of centrifuge, the high-speed operation, the protection of vulnerable parts and the use of materials are considered in the manufacturing process of crown solid control. Long time operation and less maintenance ensure the efficiency and economic benefits of the equipment.

In the cuttings drying system, mud tanks are used to hold equipment and collect and store drilling fluids. Cuttings discharged from the drying device and centrifuge into the dryer can be conveyed through the screw conveyor device, which is widely used to transport solid materials.

GN oily sludge treatment system for Asia project

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.
