Optimisation Of Ammonia Injection For An
Efficient Nitric Oxide Reduction
Author(s)

Abstract
Dry flue gas cleaning systems using activated coke as a catalyst reduce sulphur
dioxide and nitric oxide emissions. The sulphur dioxide reduction in this system
has an efficiency of over 98%. Therefore, the main purpose is the optimisation of
the NOx reduction process by means of ammonia injection optimisation. Such a
flue gas cleaning system is currently in operation at the Industriepark Hoechst
site in Germany. This paper shows the analysis of the ammonia load on activated
coke and denitrification experiments in laboratory scale under variation of
different parameters. The results of the ammonia loading tests show a relation
between temperature and loading capacity. The tests were driven for
temperatures between 110 and 469°C. The denitrification tests pointed out that
the highest efficiency is obtained with the activated coke loaded at the highest
temperature at 469°C.
Keywords: ammonia, activated coke, nitric oxides, denitrification, dry flue gas
cleaning, adsorption.
