Chapter 44.4.17 Minimisation of NO x emissionsDescriptionThe formation of NO x has to be considered in the following cases:• burning of sulphur or gases containing sulphur at higher temperatures• decomposition of spent acids• roasting sulphidic ores and pyrite.NO x levels can be minimised by applying low NO x burners.Achieved environmental benefits• for sulphur burning, NO x levels of 20 mg/Nm 3 can be achieved.Cross-media effectsNone believed likely.Operational dataNo specific information provided.ApplicabilityGenerally applicable.EconomicsNo specific data provided.Driving force for implementationLower emissions of NO x and product quality.References to literature and example plants[57, Austrian UBA, 2001]202 Large Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers
Chapter 44.4.18 Treatment of waste watersDescriptionWaste water streams arise mainly from wet scrubbing, in particular from the cleaning ofmetallurgical tail gases, from cleaning pyrite roasting gases and from cleaning gases from spentacid regeneration.Waste waters are treated by sedimentation, filtration/decantation to remove solids. The wastewaters might require neutralisation before discharge.Achieved environmental benefits• lower waste water emission levels.Cross-media effectsNone believed likely.Operational dataNo specific information provided.ApplicabilityGenerally applicable.EconomicsNo specific information provided.Driving force for implementationLower waste water emission levels.References to literature and example plants[57, Austrian UBA, 2001, 58, TAK-S, 2003]Large Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers 203
