AbstractTreating steam condensate systems with neutralizing and filming amines has been commonplace in industry for several decades. Refinery steam and condensate systems are often considered “tough to treat” due to their complex configuration and uses of the steam – direct injection in furnaces and distillation towers flash-steam reboilers high alkalinity make-up water sources multiple opportunities to introduce hydrocarbon contaminants and several other factors – requiring extra attention to maintain good system protection while minimizing impact on the process. Specifically improper selection and application of steam neutralizing amines can contribute to salt-induced fouling and corrosion in crude overhead systems. In response technology development in the areas of amine performance modelling neutralizing amine selection and the use of volatile filming corrosion inhibitors facilitates steam system protection and avoids process system salting. This paper will discuss design application and benefits of utilizing an integrated approach to develop programs to both protect the steam system and avoid negative impact to the refinery process. Several refinery case studies will be included.

Key words: Corrosion, Reboiler, Condensate, Boiler Water Treatment, Polyamine, Low-Salt Amines
