Several experiences with the use of titanium heat exchangers in refining processes are summarized. These involve distillation column overhead condensers in atmospheric crude distilling units, fluid catalytic cracking units, delayed coking units, and sour water strippers. The causes of problems are discussed. Needs for additional data are highlighted.
Corrosion under Insulation (CUI) and External Corrosion continue to be a major issue for Petrochemical facilities. Refineries have been investing in a CUI and External Corrosion inspection program. This paper details the methodology for addressing this damage and lessons learned throughout the implementation.
Experimental results and findings from a joint industry program entitled “Prediction and Assessment of Corrosion in Amine Solvents” conducted over the period from March 2003 to May 2007. An overview of experimental methods, observed results and trends, as well as comparison of predicted corrosion rates to refinery field data.
