GN Separation recently supplied decanter centrifuges to an Asia-based drilling company to support its solids control and drilling fluid management operations. The delivery included 2 sets of GNLW363D-VFD centrifuges and 1 set of GNLW453D-VFD centrifuge. These units will be used on drilling sites to optimize the separation of solids from drilling mud, reduce waste, and improve overall fluid recycling.
About the Models
✅ GNLW363D-VFD
This is GN’s workhorse 14-inch bowl VFD-controlled decanter centrifuge. It is designed for fine solids separation in drilling fluids processing. The variable frequency drive (VFD) allows operators to adjust the bowl speed and differential speed, optimizing the separation cut point depending on the mud properties. Typical bowl speeds can reach up to 3200 RPM. The 363D-VFD is widely used in oil and gas drilling solids control systems, offering reliable performance even under high solids loading.
✅ GNLW453D-VFD
This is a 18-inch bowl VFD decanter centrifuge designed for higher capacity requirements. With a larger bowl diameter and longer beach, it can process higher flow rates while maintaining good separation efficiency. The VFD control allows flexible adjustment of operating parameters, making it suitable for different mud weights and drilling conditions.
Application in Drilling Operations
Drilling operations require precise solids control to maintain the quality of the drilling mud and reduce disposal costs. Decanter centrifuges are a critical component in modern solids control systems. They remove fine and ultra-fine solids that cannot be separated by shale shakers or desanders alone. By deploying GN’s VFD-controlled centrifuges, the drilling company can:
- Maintain optimal mud weight and properties
- Minimize dilution costs
- Reduce waste volume for disposal
- Improve overall drilling efficiency
Advantages of VFD-Controlled Centrifuges
Variable Frequency Drive (VFD) technology provides the flexibility to adapt centrifuge speed to different fluid conditions. Operators can slow down the bowl to reduce wear when handling lighter mud or increase speed for finer separation. The control panel also allows adjusting conveyor differential speed for better solids dryness.
Why GN Decanter Centrifuges?
GN Separation has years of experience manufacturing decanter centrifuges specifically for the oil and gas industry. Its centrifuges are designed for field conditions, offering robust construction, stainless steel bowls, tungsten carbide protection, and user-friendly controls. The VFD models are skid-mounted for easy integration into existing solids control systems.
By choosing GN’s GNLW363D-VFD and GNLW453D-VFD units, the Asia-based drilling company strengthens its solids control capability, ensuring better environmental compliance and lower operating costs on its drilling projects.
