Corrosion Chemistry

Understanding the corrosion tendency of oil sands-derived crudes starts with proper and accurate measurement of the acidic components of the crude. The new thermometric method for measuring TAN has shown promise for asphaltene containing crudes and it is soon expected to replace potentiometric method ASTM D664. Identification of corrosive naphthenic acids and sulphur species in bitumen and their interactions at high temperature is essential to identify the cause of corrosion and subsequently come up with proper mitigation strategy. Measuring corrosion rates using laboratory equipment is challenging at best. Developing methods and techniques to mimic refinery conditions must be included as part of the activities of all laboratories involved in petroleum research. The activities in corrosion studies include, but are not limited to:

  • Investigating the corrosivity of crudes in collaboration with CCQTA

  • NA speciation using FTICR mass in collaboration with Florida State University

  • Thermal chemistry of naphthenic acids

  • Comparing the reactivity of NA in different crudes
  • Sulphur speciation in collaboration with Florida State University and CCQTA
