High speed decanter centrifuge for Oily sludge separation

GN Solids Control provides a specialized oily sludge separation system designed to reduce waste and maximize resource recovery through a combination of heating and chemical washing. With proper chemical dosing, the system achieves efficient separation results. After treatment by the decanter centrifuge, the oil content in discharged solids is typically reduced to around 1–3%, significantly minimizing environmental impact and disposal costs.

The system also incorporates a 3-phase decanter centrifuge for oil recovery. The recovered oil typically has a BS&W (Basic Sediment and Water) content of 2–3%, making it suitable for resale to refinery companies. To ensure optimal performance, the feed material entering the 3-phase centrifuge should contain less than 10% solids and have particle sizes smaller than 2 mm. If the sludge does not meet these conditions, a 2-phase decanter centrifuge is required beforehand to pre-process the material and remove excess solids.

In addition to oil recovery, the system also handles wastewater. The water discharged from the 3-phase centrifuge generally contains 1000–3000 ppm of residual oil. This recovered water can be reused within the treatment system itself, particularly in the premixing tank. For stricter environmental compliance, clients have the option to integrate an additional water treatment unit, reducing the oil content to 50–100 ppm. Alternatively, the water can be sent to a third-party slurry treatment company for further processing.

GN Solids Control does not supply the chemicals used in the process. Clients are responsible for selecting appropriate reagents based on the characteristics of their specific waste materials.

The system offers flexible feeding methods depending on sludge condition. For highly flowable sludge, a vacuum pump can be used to transfer material directly into the system. For thicker, dryer sludge collected at the bottom of pits, it is more effective to use an excavator for mixing and then transfer the material into a premixing tank prior to separation.

By combining efficient oil recovery, solids reduction, and wastewater reuse, GN’s oily sludge separation system provides a practical and cost-effective solution for environmental waste management.

High speed and low speed decanter centrifuge for drilling mud system

The GNLW363G is a 14-inch decanter centrifuge widely applied in the oil and gas drilling industry, known for its efficiency and versatility in handling drilling fluids. GN Solids Control provides this model with three different drive options to meet varied operational needs and budget requirements: a stable fixed-speed version, a fully hydraulic drive (FHD), and a variable frequency drive (VFD) for adjustable operation. This flexibility allows drilling operators to choose the most suitable configuration based on project demands, cost considerations, and site conditions.

One of the common challenges operators face is selecting the right centrifuge speed for their specific application. The speed of a centrifuge directly influences the separation efficiency, making it a critical factor in drilling mud treatment. To address this, GN Solids Control emphasizes the importance of understanding the role of centrifuges within a complete drilling mud system.

Typically, a full drilling mud system incorporates two centrifuges working in tandem, each serving a distinct function. The first is the low-speed centrifuge, which is primarily used to recover barite. In weighted drilling fluids, barite is added to increase mud density. By operating at a lower speed, this centrifuge selectively recovers barite particles from the mud, helping to maintain the required density while reducing mud weight and cutting down on material costs.

The second is the high-speed centrifuge, which becomes essential after the drilling system has been in circulation for a period of time. During extended operations, ultra-fine solids gradually accumulate in the drilling fluid. These particles are too fine to be removed by hydrocyclones. The high-speed centrifuge is specifically designed to remove these ultra-fine solids, preventing the mud weight from rising uncontrollably. The solids separated at this stage are discharged as waste, while the cleaned fluid is returned to the system for reuse.

By employing both low-speed and high-speed centrifuges, operators achieve optimal drilling fluid management. The GNLW363G, with its range of drive options and reliable design, provides a comprehensive solution for efficient solids control, improved mud quality, and cost-effective drilling operations.
