Abstract Details

2024, Doctor of Philosophy (PhD), Ohio University, Chemical Engineering (Engineering and Technology).
Oil refineries must adapt to unfamiliar crude oil chemistries originating from modern unconventional oil resources. Additionally, they face statutory requirements to co-process acidic bio-oils with ordinary crude oils. This results in exotic crude chemistries which can aggravate concerns for naphthenic acid and sulfidation corrosion related failures, amongst other processing challenges. Therefore, a reliable corrosion prediction tool becomes indispensable for oil refineries to ensure the safety and integrity of processing/distillation units while refining these unconventional oils. For the construction of such a corrosion prediction model, the reaction mechanisms of both naphthenic acid and sulfidation corrosion are further deciphered in this dissertation research. Associated kinetic equations are modeled to calculate the rates of the proposed elementary steps. These elementary rate equations are combined using mass conservation principles to obtain equations for overall corrosion rates. The derived corrosion rate equations capture the trends of experimental corrosion rates with respect to time, temperature, and concentrations of corrosive species. The phenomenological coefficients of the kinetic equations are derived from experimental and literature data. A computer program consisting of the derived kinetic equations has been built for the prediction of refinery corrosion. Simulations of the corrosion rates with respect to system parameters have been demonstrated.
