Catalyst Technology NOx
By using NOx catalyst impregnated filter elements, very compact combination modules can be provided for many applications. For applications where the combination may involve risks, a separate KAT module is installed directly behind the filter instead.
In these module units, catalyst poisons can be removed from the raw gas via entrained flow dry sorption at process temperature. This avoids the need for costly cooling and reheating of the gas as in gas scrubbing.
