Chapter 1010.4 Techniques to consider in the determination of BAT• for product cooling, see Section 7.4.5• for recycling of warm air, see Sections 7.4.6• concerning granulation recycle, see Sections 7.4.7.10.4.1 Avoiding diffuse emissions from curingDescriptionIn direct granulation, the product is not stored for curing, hence less diffuse emissions occur.However, direct granulation requires reactive phosphate rock and might cause losses of plantavailable P 2 O 5 due to the incomplete reaction.Achieved environmental benefits• direct granulation is a measure to reduce the potential for diffuse emissions from curing.Cross-media effectsDirect granulation might cause losses of plant available P 2 O 5 .Operational dataNo information provided.ApplicabilityDirect granulation requires reactive phosphate rock to reduce the amount of not plant availableP 2 O 5 . In the case of indirect granulation, the curing section can be designed as an indoor systemand the vent from the curing can be connected to a scrubber system or to the granulation section.EconomicsNo specific information provided.Driving force for implementationCost savings.References to literature and example plants[52, infoMil, 2001, 154, TWG on LVIC-AAF, 2006], Donauchemie394 Large Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers
