Abstract

It is generally accepted that nitrogen oxides, together with sulphur dioxide, are the main cause for the phenomenon of acid precipitation and its destructive effects on man's ecosystem. For example, EC Directive 88/609 specifies the maximum content of nitrogen oxides in flue gases from large scale power stations at 200 mg/m3. As these low concentrations cannot be obtained by primary measures alone, special processes are required for the removal of nitrogen oxides (denoxing processes). In order to develop a regenerative denoxing process based on the absorption of NO in aqueous solutions of Fe(II)EDTA, investigations were carried out concerning the equilibrium thermodynamics of this reaction. The present study is based on 35 experiments which cover a temperature range from 4 to 90 C.
