 GRRO: Tech Specs
The resulting dry material is discharged from the bottom of the cyclone with the water-entrained airflow exiting the top of the cyclone and passing through a scrubber to remove particulates, water particles and water-soluble compounds.
The Pre-Separation Cyclone uses air to agitate, separate and accelerate the material, further reducing the particle size and releasing water from the surface of the particles.
In general, a mixture of water vapor and air from the Separation Cyclone is discharged into the wet scrubber, which slows and cools the mixture.

 Flux Management White Paper
The gas passes through the condensing chamber in the lower section of the flux separation box (B) and is cooled by ambient air blown on the outside of the box (C, Photo 1).
These blowers spin the flux laden gas and cause the flux particles to separate from the main gas stream as in a cyclonic separator.
Much of the flux separation technology utilized in Generation 4.1 such as air to gas cooling, cyclonic separation, as well as gas recirculation into the cool zone are proven methods that have been used for many years on previous Heller flux management systems.

A concept has been formulated and developed of the formation of the Antarctic Intermediate Water (AAIW) due to the frictional decay of cyclonic eddies at the Subantarctic Front (SAAF) generated as a result of the separation of cyclonic meanders from this front.
A numerical model of this phenomenon has been formulated and calculations have been made using the model that illustrates the process of low-salinity water sinking from the surface layer to the intermediate layer due to eddy decay with a simultaneous isopycnal mixing of the eddy water with the surrounding water.
/sec, ten cyclonic eddies which are formed within a year in the Pacific sector of SAAF are enough to maintain a stable salt content of AAIW in the Pacific Ocean.
