Waste Air Purification
Our service portfolio is characterized by a wide range of different applications from VOC minimization, to the removal of smells and process optimizations. Starting with the analysis of the actual state, through to the erection of turn-key lines and the servicing of these.
Technologies
Biological Waste Gas Treatment:
Is used for low concentrated volume flow rates.
Chemical/Physical Waste Gas Treatment:
Compared to biological treatment for higher polutant concentration.
Catalytic Treatment:
For recovering sulfurous substances from waste gases in the form of highly concentrated sulfuric acid. At the same time it makes use of the ensuing process heat to produce steam.
Methods | Volume flow [m³/h] | Emission concentration [g/Nm³] |
|---|---|---|
 BIOGATSignificant reduction of H2S- and CS2-waste gas. | 1.000 bis > 300.000 | 0.1 to 1 |
 BRI - BIOREACTIONEfficient reduction of VOCs (such as methanol, formaldehyde), hydrogen sulphide, NH3 etc. | 1.000 bis > 300.000 | 0.1 to 0.5 |
 ScrubberReduces vapours and emissions of agressive chemicals. | 100 bis 100.000 | 0.1 to 50 |
 TOPSOE WSATo recover sulfurous substances from waste gases in the form of highly concentrated sulfuric acid. | 10.000 bis 100.000 | 1 to 15 |
 CS2 - CONDENSATIONRecovery of CS2 from the manufactoring of Viscose-staple fibres. | - | > 1000 |
