The CDS SpiraFlow™ cyclone provides a high degree of separation of fine droplets and foam even at high operating pressures. It can be positioned vertically or horizontally within a vessel and due to its high capacity is ideal for the revamping of existing vessels. For new build applications the vessel size with these internals can be substantially reduced leading to considerable vessel cost and weight savings. The SpiraFlowTM cyclone is very efficient with increasing pressure and low surface tension liquids.  

 

Operating Principle

The mist enters the cyclone and flows through the swirl element causing an intense gas rotation. The droplets are separated by the subsequent centrifugal action and are coalesced into a liquid film on the cyclone inner wall. This liquid film is purged out of the cyclone by combination of the rotating flow and the secondary gas flow. This secondary flow is then recombined with the main flow through a pipe leading to the centre of the cyclone.

Operating Characteristics

Separates all mist droplets > 5µm (Atmospheric Conditions)
