Abstract Scope Asphaltenes are surface active molecules that lie within the aromatic composition group of petroleum. Asphaltene fouling and corrosion of petroleum handling equipment has caused much productivity and remediation loss to the oil and gas industry. At ambient temperatures, asphaltenes are proposed to coalesce into precipitates and adhere to surfaces. Asphaltenes can also build-up as multilayer foulants because of cohesive forces between the adhered asphaltenes and those in solution. At high temperatures, the asphaltene deposition mechanisms are less understood. Corrosion, especially sulfur-based is commonly observed during failure analysis of ruptured components. In this study, a combined x-ray photoelectron spectroscopy and transmission electron microscopy characterization has been used to study the link between asphaltene-driven corrosion and fouling at high temperatures (up to 350 °C). The results of this study can help extend the current models on asphaltene deposition to high temperatures where alternate deposition mechanisms become active.
