Review and Survey of Alkaline Carbonate Stress Corrosion Cracking in Refinery Sour Waters

Explores the trend of the increasing number of reported incidents of alkaline carbonate stress corrosion cracking (ACSCC) since the year 2000. Includes information on where ACSCC has occurred in process equipment in petroleum refining service; the refining community and current theories on the conditions and mitigation techniques that may have an impact on this type of damage; analytical and inspection techniques that have been used to address the issue; as well as results of a 2006 industry-wide survey on ACSCC that provides data from three process groups fluidized catalytic cracking units (FCCUs), sour water strippers (SWSs), and cokers.
