Aeromix™ scrubbers

  

Aeromix™ scrubbers are a unique low energy venturi design. Unlike most venturis, in the Aeromix the gas flows upwards through the venturi throat. The gas flow carries the scrubbing liquid upwards to the entrainment separator where it disengages and flows by gravity back to the liquid feed tank. From the liquid feed tank it flows by gravity back to the venturi throat.

  • No pump or spray nozzles are required
  • Gravity recirculation
  • Slurries to 30% w/w can be used
  • Low pressure drop of 1 to 2 kPa
  • Up to 99% efficiency on 2 micron particles

Fabric Filters    

Fabric Filters use an array of filter bags contained within a housing to filter out dusts and particles from a gas stream. Very low outlet loads of <10 mg/Nm3 can be achieved, including on very sub-micron particle sizes. Different bag materials and filter types are available to suit different applications and operating environments.

  • Reverse pulse
  • Reverse air
  • Shaker
  • Cartridge
  • Pre-assembled modules for small applications
  • Bag lengths to 8 metres for large applications

Flue Gas Scrubbing Systems Spray tower gas absorption using a slurry for the absorption of acid gases. Simple, non fouling design.
Wet/Dry Scrubbing Systems   The scrubbing agent in the form of a slurry is injected into a spray drier/absorber using patented two fluid nozzle technology. The finely atomised liquid absorbs acid gases whilst the heat of the gas evaporates the droplets. The flue gas then passes through a fabric filter or electrostatic precipitator where the dried reaction products and other solid particles are collected.
Dry/Dry Scrubbing Systems   A dry absorbent is injected into the gas stream in an upflow dry reaction chamber. Acid gas is absorbed in the reactor. A fabric filter is then used to collect the reacted reagent and other particles present.
Cyclones and Multiclones   Multiclones consist of a number of cyclones arranged and operated in parallel, contained within a housing providing a common gas inlet and gas outlet to the cyclone array. Smaller cyclone diameters result in higher particle removal efficiency. Thus a multiclone system has a higher efficiency than a single cyclone for a given application.
Electrostatic Precipitators (ESP’s)  

ESP’s use electrical forces to move particles out of the gas stream and onto collector plates or tubes. A high voltage applied to electrodes induces an electrical charge on the particles, causing them to migrate to the collector surfaces.

  • Rigid discharge electrode precipitator with magnetic impulse rapping
  • World’s largest ESP on a coal fired boiler
