Cyclones are used for the pre-dedusting of waste gases with high dust load; Dry electrostatic precipitators HESP) are used for the dedusting of waste gases in the non-ferrous metallurgy, the iron and steel industry and the glass industry and for FCC units in refineries. Dry ESPs can reach high dedusting efficiencies of more than 99, 9%

For efficient removal of mists and dusts from airstreams. Units can include a series of liquid sprays in the gas inlet manifold. Wet cyclones are ideal for air streams with particulates or where solids deposition is possible. Being large and open, they cannot clog or block, and are easily cleaned. USES • Mist elimination for venturi scrubbers. • Particulate collection in fertiliser applications. • Particulate collection from driers. • Conditioning of air stream for biofilter.

Venturi scrubbers for a broad range of applications scrubbing gases with particulate loadings and soluble gases. They are particularly effective in the sub micron range. Manufactured under licence to Verantis of the USA. The main capture process is inertial impaction; the air stream and scrubbing liquid are accelerated through a throat and the resulting turbulence results in solid particles impacting scrubbing liquid particles, and capture results. Long throat venturi scrubbers provide removal efficiencies in excess of 99% when removing solid and liquid particles of 0.1 to 5 microns from corrosive gas streams. The venturi throat size is selected to achieve the design velocity and pressure drop for optimal mixing contact.

Wet Scrubbers are effective air pollution control devices for removing particles and/or gases from industrial exhaust streams. Wet scrubbers operate by introducing the dirty gas stream with a scrubbing liquid – typically water. Particulate or gases are collected in the scrubbing liquid. Wet scrubbers are generally the most appropriate air pollution control device for collecting both particulate and gas in a single system..

High-velocity cyclonice scrubbers are a traditional and well-known method for removing fine dust particles from industrial air streams. Venturi scrubbers, (including ejector venturis and eductor venturis), are often installed to remove fine particles from volatile, hazardous or corrosive gas streams, or gas streams containing solid materials that are difficult to handle. They have been widely used throughout the chemical industry for decades. The collection efficiency and return-on investment realized with venturi scrubbers are equal, in most cases, to that of a baghouse or electrostatic precipitator. Venturi scrubbers have a somewhat lower performance efficiency, and (due to their use of high-pressure fans and other factors) a significantly higher operating cost, than a Cloud Chamber Scrubber.
