Carbonate Stress Corrosion Cracking of Carbon Steel in Refinery FCC Main Fractionator Overhead Systems

Intergranular cracking and faiulure of carbon steel piping and vessels of FCC Main Fraqctionator overhead systems in NH3-H2S-CO2- containing environments is attributed to carbonate stress corrosion cracking. From plant water sampling program, cracking is correlated with water chemistry, open circuit potential and pH.
