Laboratory exposure testing of carbon steel to water from different regions of the United States, with varying chemistries and chloride content. The results of chemical analyses conducted in the laboratory, including elemental analysis by SEM/EDS and analysis by x-ray diffraction are correlated to water chemistry.
A major fire in a Reactor Effluent Air Cooler (REAC) of the Hydrocracker Unit (HCU). Visual inspection was made on the failed portion. Metallurgical investigation, macrostructural and microstructural analysis, Scanning Electron Microscopy, and Energy Dispersive x-ray Spectroscopy was conducted on the failed air cooler.
