7.4 Techniques to consider in the determination of BAT7.4.1 Minimisation of NO x formationDescriptionChapter7NO x loads in exhaust gases from the digestion of phosphate rock can be minimised by aselection of proper operating conditions, e.g. temperature control and correct ratio of rockphosphate/acid. If the digestion temperature is too high, NO x is formed excessively. NO xformation can also be reduced by using phosphate rock with low contents of organic compoundsand ferrous salts.Achieved environmental benefitsMinimisation of NO x formation. An example is reported by [78, German UBA, 2001]:NO x emission using Florida rock (IMC): about 425 mg/m 3NO x emission using Russian rock (Kola):
