The CDS-GasunieTM Cyclone Scrubber can be used for separation of liquids (water, hydrocarbon, glycol, etc.) from gases (natural gas and other), for the protection of downstream equipment (compressors, gas turbines, flow meters, etc.). Solid particles (dust, sand, etc.) will also be removed, making the scrubber suitable for use as a gas wellhead separator.

Operating Principle

The optimised blade geometry brings the combined phase into rotation. The resulting centrifugal force moves the liquid and solid particles towards the vessel wall, where they form a liquid film flowing downwards to the bottom of the vessel. The gas exits the vessel through the central pipe connected to the gas outlet nozzle. The baffles in the bottom of the vessel stop the rotation of the liquid, and the blocking plate prevents liquids from being entrained with the gas. In this way it is ensured, that no gas carry under or liquid carry over can occur.

Advantages

• Small size and weight as a result of high allowable gas load factor. Therefore especially attractive for offshore applications.
• Maintenance friendly: No small channels or downcomer pipes. Low fouling tendency.
• Excellent slug handling capabilities.
• High turndown.
• Available as retrofit package.
• Over 200 references in a wide variety of applications.
