Catalytic incineration in the chemical industry
Ion exchanger resins for water softening are produced at a chemical production site. During the various production steps, a large number of inorganic and organic pollutants are released that are then collected in the exhaust air and need to be cleaned to comply with the strict statutory regulations.
Challenge
- Different inorganic and organic pollutants in the exhaust air
- High safety standard in the chemical industry
Solution
- Multi-level exhaust air treatment
- Catalytic incineration for reduction of the organic pollutants
- DeNOx level for denitrification
- Absorption of the inorganic pollutants
- Two-level heat recovery
Period
- Commissioned September 2006
Facts about the project
- Volume flow of exhaust air 12,000 Nm³/h from the ion exchanger production
- Solvent concentration of exhaust air is a mean max. 2 g/Nm³
- Various hydrocarbons, nitrogen oxides, inorganic compounds
