The alternatives described at the regenerative thermal and catalytic post-combustion also applies to this technique.
The advantages of regenerative catalytic post-combustion are: No problems with corrosion of the exchanger Homogenization of the gas flow in the bed Energy recuperation far pushed through Relatively lower functioning costs More compactly than thermal oxidation Lower oxidation temperature so that less support fuel is necessary Low NOx production; approximately 20 - 30% of the NOx at thermal post-combustion CO are destroyed with the other components High constant and reliable performances possible By the low temperature less heat insulation has been required than
at thermal post-combustion More lower fire risk with respect to thermal oxidation
The disadvantages are: More lower output for VOC disposal than thermal oxidation System are sensitive for changes in energy-input of the gas Risk of dioxin shaping connections chlorinated at presence of All catalysts are liable to catalyst far grants and polluting
substances. Substance must be removed for post-combustion Deactivated catalyst can be regenerated not but must be removed. High investment costs Can hide the ceramic beds At discontinue functioning must be again warmed up the bed every
time Large scope and weight Much maintenance of moving parts
In most of the cases thermal regenerative system are placed instead of
catalytic since the thermal output is already very high. A catalytic system is in comparison more expensive.
