Centrifugal Degasser

Dec 17, 2025

The centrifugal degasser (centrifugal vacuum degasser) is a high-efficiency degassing unit specifically developed for gas-cut drilling fluids. By utilizing the principle of centrifugal separation, the device rapidly isolates and discharges entrained gases from the drilling fluid, ensuring the stable operation of the circulation system. Typically installed downstream of the shale shakers, it is widely used in drilling mud treatment systems, solids control systems, and mud purification processes for trenchless engineering. The equipment not only restores mud density and maintains viscosity stability but also reduces drilling costs and enhances operational safety. Additionally, the centrifugal degasser can function as a high-power agitator, helping to maintain a homogeneous state of the mud during circulation.



Operational Process of Centrifugal Degasser
During operation, the centrifugal vacuum degasser generates powerful centrifugal force via rotating components, exponentially increasing the buoyancy force on gas bubbles to accelerate their rising and separation. Once the bubbles reach the liquid surface, the gas is rapidly released and further broken down by turbulent action. Subsequently, an integrated blower extracts the separated gas and discharges it into a safe zone or a flare system, achieving a high-efficiency and secure degassing operation.



Technical Advantages of Centrifugal Degasser
Compared to traditional vacuum degassers, the centrifugal model offers advantages such as a compact structure, flexible installation, and stable operation. The unit can be installed directly inside the mud tank without occupying additional tank-top space, making it ideal for drilling sites with space constraints. Its modular design integrates the centrifugal cylinder, filtration components, motor, and supports, facilitating easy maintenance and replacement.

Performance and Efficiency of Centrifugal Degasser
The centrifugal vacuum degasser is capable of handling high gas-cut conditions while maintaining high throughput, low energy consumption, and high efficiency. In continuous drilling operations, it significantly improves mud performance, prevents density anomalies caused by gas retention, and provides a more stable medium for the drilling pumps and downstream equipment.



Applications and Future Outlook
Currently, this equipment is widely deployed on onshore and offshore drilling platforms, geothermal wells, shale gas extraction projects, and horizontal directional drilling (HDD) operations. Its reliable performance and superior gas-liquid separation efficiency make it an indispensable component of modern mud circulation systems. Moving forward, with the advancement of automation and intelligent monitoring technologies, the centrifugal vacuum degasser will further enable real-time parameter adjustment and intelligent diagnostics, providing even more precise and efficient solutions for drilling fluid treatment.
