Chapter 44.4.13 Maintaining heat exchanger efficiencyDescriptionThe efficiency of heat exchangers is affected after years of operation by build-up of dirt andcorrosion. Maintenance of internal or external heat exchangers ensures that heat is removedefficiently from the converter and, hence, enables optimum catalyst activity. Where heatexchangers cannot be cleaned, replacement has to be considered.Achieved environmental benefits• contributes optimum catalyst activity.Cross-media effectsNone believed likely.Operational dataNo specific information provided.ApplicabilityGenerally applicable.EconomicsNo specific information provided.Driving force for implementationIntegrated measure to minimise SO 2 emissions.References to literature and example plants[17, 2nd TWG meeting, 2004]Large Volume Inorganic Chemicals – Ammonia, Acids and Fertilisers 193
