Corrosion in Fuel/Natural Seawater Environments

Abstract

Experiments were designed to evaluate corrosion-related consequences of storing/transporting petroleum and alternative fuels in contact with natural seawater. Fuels included petroleum JP-5, camelina derived JP-5, petroleum F-76, algal derived F-76, and mixtures of the petroleum-based and alternative fuels. Corrosion rates were estimated from polarization resistance measurements and corrosion was measured by weight loss. Corrosion attack morphology and corrosion products were analyzed by three-dimensional profilometry, environmental scanning microscopy, and energy dispersive spectroscopy. Alternative fuels stimulated sulfide production in seawater indicating that the alternative fuels were more biodegradable than their petroleum-based counterparts. Chlorides and sulfides could be detected in all corrosion products when seawater was present. Weight loss did not correlate with instantaneous corrosion rates or with dissolved sulfide concentrations in the seawater.
