Solinox process for the catalytic reduction of nitrogen oxides in flue gases

In the Solinox process, nitrogen oxides are subjected to catalytic reactions with NH//3. The mechanism of the selective catalytic reduction (SCR) is considered in detail, with attention also being paid to avoidance of undesired side reactions (such as NH//3 oxidation and formation of NH//4HSO//4). Measured results from a pilot plant are given for a number of operating cases. Essential design parameters for future plants are presented.
