Fume Scrubbers
Shivas
Shivas commitment to workplace safety extends to the environment also.Having removed hazardous fumes from industrial or laboratory processes, the safe capture of these can be achieved either by Carbon Filtration or Scrubbing. Scrubbing presents a large surface area of liquid to the gasses which are in turn absorbed into it. This provides a convenient method of disposal such as Effluent Plant for treatment, Containerisation or Neutralisation within the scrubber. Scrubbers are available in a number of different types such as the Pack Ring tower or the modern option of Vortex scrubbing as developed by SHIVAS. The advantage of the Vortex scrubber is its low maintenance requirement with few consumable components.
Counterflow separators
Shivas
Counter Flow fume scrubbers are designed for contaminants, which are difficult to absorb for all airflow requirements. The Counter Flow design offers advantages in the efficient and effective use of scrubbing solutions, as well as in a higher separator efficiency, especially for deep beds of packing. High removal efficiency is advantageous where the contaminants are highly offensive or have recovery value. In this design mist and separating solutions carry-over at high gas velocity is minimized by the use of dry packed bed mist eliminators.

Counter Flow separators are available with a variety of tower internals; each designed to achieve a maximum in efficiency at a minimum of cost. The separators are available with packed beds in height ranging from 1.2 metres to 6.0 metres. The choice between B and C Series separators must be based upon headroom required separating efficiency and future exhaust requirements. Series B separator internals may be modified so as to achieve separating efficiency equal to Series C separator.

Standard fume separators are packed with 50mm plastic tower fill, eg tellerettes give a higher target efficiency with mist and light dust problems.

Corrosive Resistant Construction from :
  • Polyvinyl chloride sheet (PVC)
  • Polypropylene sheet
  • Polyvinyl dene fluoride sheet (PVDF)
  • Polyethylene (PE)
Crossflow separators
Shivas
The series A fume scrubbers are designed for all airflow with gaseous contaminants, which are present in low concentration and/or are highly soluble in water. Series A separators offer an advantage as to low initial cost, low operation and maintenance cost and relatively high removal efficiency.

The Cross Flow design offers added advantages as to low water requirements, low-pressure drop and fan cost. In this design elimination and scrubbing solution carry-over is minimized by the back of the packed bed, which is operated dry. Efficiency of this design of internal corrugated walls prevents the gas and scrubbing solution from bypassing the packed beds.

  • Polyvinyl chloride sheet (PVC)
  • Polypropylene sheet
  • Polyvinyl dene fluoride sheet (PVDF)
  • Polyethylene (PE)
  • Fibreglass (FRP)
