Packed Bed Filter

Packed Bed Filter

For more than 20 years now, this has been the major technology in the ceramic industry and is known there as the best available technology for selective non-catalytic gas and solid reactions.

Furthermore, the packed bed filter technology can be used in certain plants for separating particles and organic components from flue gases released by waste-to-energy plants.

Almost any reactive or catalytically effective material with sufficient flowability can be used as filter granulate for absorbing specific gaseous pollutants.

In the Babcock Noell packed bed filtering plant, the reaction between the adsorbent, usually calcium carbonate (limestone) and the pollutants (mainly HF, SOx and HCl) in the flue gas, takes place in the reaction zone where the flue gases continuously pass through the adsorbent sinking due to gravity.

The Babcock Noell packed bed filtering plants are suitable for gas temperatures of up to 450° C and, therefore, are very efficient in reducing HF, SOx and HCl emissions in flue gases.
