Polypropylene as regenerable absorber for PCDD/F emission control.
A new method for the PCDD/F reduction in exhaust gases of incineration plants is based on the property of polypropylene (PP) of interacting with PCDD/F to a variable degree depending on the temperature. After having been loaded with PCDD/F at approx. 80 degrees C, the PP absorber material can be regenerated by a temperature increase of about 50 degrees C. Hence, PP can be applied in a closed cycle as a thermally regenerable PCDD/F separator without an additional waste flow being generated. The setup of the pilot plant and the first results achieved shall be described.
