Aminoacidic gases react in the sulfur production furnace; what are the main reactions that occur with NH3, and how can it be ensured that nitrogen oxides are not formed? I hope experts can give some advice
According to the explanations provided by the technicians at Dutch Duke Company, theory is quite consistent with practice. The decomposition of ammonia is based mainly on three reaction mechanisms. All three empirical reaction mechanisms require a sufficiently high reaction temperature (>1300°C) in order to completely decompose NH3. 2 NH3 + 3/2 O2 = N2 + 3 H2O (1) Combustion decomposition of ammonia; 2 NH3 = N2 + 3 H2 (2) Thermal decomposition of ammonia. H2S + 3/2 O2 = SO2 + H2O (3a) Reaction of ammonia with SO2; 2 NH3 + SO2 = N2 + 2 H2O + H2S (3b) Reaction of ammonia with SO2
2 NH3 + 3/2 O2 = N2 + 3 H2O – Combustion and decomposition of ammonia. 2 NH3 = N2 + 3 H2 – Thermal decomposition of ammonia (at high temperatures above 1250 degrees). 2 NH3 + SO2 = N2 + 2 H2O + H2S – Reaction of ammonia with SO2
2 NH3 = N2 + 3 H2 Thermal decomposition of ammonia: The decomposition of ammonia-containing gases is primarily considered to occur at temperatures above 1250 degrees. Whether complete decomposition is possible also depends on whether the gas velocity and distribution in the reactor are uniform.
