AQUAFIL Engineering has long experiences and several long term clients that are using continuously the mist eliminator systems for different applications.

AQUAFIL Engineering builds units for the following industries :

  • Plastics
  • Textiles
  • Rubber
  • Synthetic Fibers
  • Chlorine
  • Cellulose & Paper
  • Phosphoric Acid
  • Fertilizer
  • Nitric Acid
  • Metal
  • Sulphuric Acid
  • Others

There are many different production processes that generate fine organic aerosols and mists, e.g.

  • Extrusion, injection moulding, blowing, etc.
  • Coating of textiles, metals, papers, etc.
  • Thermofixation of textiles.

In the nylon production plants of the AQUAFIL Group at the spinning and casting die heads, monomers and oligomers are sucked off and led to the AQUAFIL Engineering mist eliminator. Several waste gas streams can be combined to one stream with a central mist eliminator. The cleaned air leaves the plant and the separated products return to the plant.

In all these cases, hydrocarbons are evaporated that condense in the atmosphere and generate fine mists with a high light scattering effect and therefore high opacity. Pollution control regulations in Germany forbid emission concentrations of more than 20mg/m3 for these products. With a mist eliminator plant designed by AQUAFIL Engineering you can easily reach the required concentrations. We can guarantee, because of our experiences, which separation efficiency will be realized in our separators under given conditions. However, sometimes it is advisable to carry out a test on site. Therefore we have a number of pilot plants available that carry out realistic tests in partial flow with a capacity up to 2500m3/h.

The basic components of this process are the AQUAFIL Engineering mist eliminators. These are filter cartridges, which are made of a dense-packed layer of special glass fiber. The filter candles are available in standard dimensions of 600mm diameter and 1500 resp. 3000 mm length. Nevertheless also customized lengths, diameters and special constructions can be delivered.

For organic mist the 3000 mm cartridge has an average capacity of 2500m3/h at a pressure drop of 300 daPa. In case of higher volumes more than one cartridge is used.
