In addition to catalytic oxidation and adsorption at activated carbon, we offer another method for the purification of waste air and exhaust gases: waste air scrubbing. Thus we cover a wide spectrum of contaminants with the most different chemical and physical characteristics.

Depending on the kind of application, we employ different types of devices, e.g. packed columns, spray towers, compact and horizontal scrubbers. For the pre-cooling of process gases, we use appropriate quenchers.

Waste air scrubbing involves the removal of contaminants or potential recyclables from polluted gas streams through physical or chemical processes caused by appropriate washing liquids.

• ammoniac, acrylonitrile, aldehydes, aerosoles, alcohols
• hydrogen chloride
• hydrocarbons and phenole
• hydrosulphide and odourous substances
• sulphure dioxide, dust etc.

We supply ready-to-operate complete plants, equipped with a switching system, metering unit and control system.
