51317--9596-Carbonate SCC Experiences in Unusual Locations

Picture for Carbonate SCC Experiences in Unusual Locations
Available for download

Cases where alkaline-carbonate stress corrosion cracking (ACSCC) occurred, including a cold wall Fluid Catalytic Cracking (FCC) Unit regenerator and a mercaptan oxidation unit. This paper discusses work done to monitor on-going ACSCC risks through sour water sampling, chemical analysis, and ionic modeling.

Typically alkaline carbonate stress corrosion cracking (ACSCC) is associated with fluid catalytic cracking unit (FCCU) sour water streams. While it has been recognized that ACSCC risks exist outside FCC sour water services there have been few published cases of ACSCC in other locations. This paper highlights several cases where ACSCC occurred in atypical locations including a cold wall FCC regenerator sour water stripper (SWS) pumparound SWS ammonia acid gas knockout and a mercaptan oxidation unit. These unusual failure locations highlight the need for a fundamental understanding of the ACSCC mechanism. This paper discusses work done to monitor on-going ACSCC risks through sour water sampling chemical analysis and ionic modeling.

As a result of a Carbonate Stress Corrosion Cracking (CSCC) event at one refinery an investigation was made into the cause and mitigation of CSCC. This paper outlines the information obtained and the development of tools that could be utilized by other refinery fluidized catalytic cracker units (FCCU's) to better assess risk of CSCC.

This paper provides an introduction on carbonate cracking and Los Angeles refinery’s recent experience with this corrosion mechanism. Also included in this paper is the methodology used for developing a risk assessment for equipment and piping susceptible to carbonate stress corrosion cracking in a fluid catalytic cracking unit (FCCU) gas plant.

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

Product Number: 51390-90206-SG
Author: J.H. Kmetz, D.J. Truax
Publication Date: 1990
$20.00

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.
