scope:

This guideline describes the state of the art of catalytic waste gas cleaning.

It serves as a basis for the choice of methods, design and operation as well as the ecological and economic evaluation of plants and catalysts for waste gas cleaning.

Questions related to the practical application of the methods have obtained top priority.

The theoretical fundamentals of the catalytic processes and process modelling are covered as regards their use for plant manufacturers and plant operators for the design and operation of catalysts and plants.

Questions regarding economical operation, plant safety and warranty are of particular importance in these guidelines.

Areas of application, for which a transferability is not always an option due to the experiences gathered here, generally require special application tests.

The guideline covers the application of the catalytic waste gas cleaning in stationary plants and processes only. The catalytic waste gas cleaning of flue gases of power plants is described in guideline VDI 3927 Part 1.

Oxidative methods and methods for catalytic reduction will be described in two following parts.

Examples and experiences of used plants are an important part of this guideline. In particular, statements about observed emission values of existing plants are made. The examples give an overview about the range and the basic conditions of the application and permit an evaluation of the transferability to new areas of application. Examples of catalytic dioxin damage are also given.
