Chemical process
Climate change and climate protection are playing an increasingly important role. Therefore the various business units of the chemical industry have committed themselves to reducing emissions, for instance ("Responsible Care").
Based on the example of a residue combustion plant in a chemical company, dusts featuring difficult cleaning properties are removed from the system. A filtering precipitator is used for waste gas dust removal.
