Causes of Tube Heater (Finned Tube) Damage in the Production of Butyl Alcohol and Methanol Synthesis

Resumo

Reasons are studied for breakdown and failure of tubular coil elements (finned tubes) designed for heating a production medium with flue gas heat before entering reaction columns. An analysis of cases of abnormal and emergency situations shows that cases of finned tube damage and breakdown occur predominantly due to infringement of operating regimes, changes in material properties during operation, and irregularities of the tube manufacturing process.
