NOx Absorption


Since NOx is one of the most harmful substances to human beings, a strict policy to avoid emissions into the atmosphere is mandatory.

Pfaudler has developed several technologies to recover NOx as nitric acid and purify waste gas to such a degree that it can be released into the atmosphere, depending on local regulations and the client’s ability to treat it further:

  1. atmospheric absorption with or without chemical additives
  2. low pressure absorption with or without chemical additives
  3. high pressure absorption

Nitrous gases are oxidized using atmospheric air and absorbed in process water.

The effluent gas complies with all environmental standards for most applications without additional treatment.

We can provide a customized solution tailored to your individual needs.

As an “end-of-pipe“ solution, Pfaudler also provides catalytic oxidation and reduction systems.
