Corrosion-Related Consequences of Biodiesel in Contact with Natural Seawater

Abstract

Experiments were designed to evaluate corrosion-related consequences of storing/transporting biodiesel in contact with natural seawater under anaerobic conditions. Coastal Key West, FL (KW) and Persian Gulf (PG) natural seawaters were used in these 60-day studies. The highest corrosion rates measured by electrochemical techniques were for unprotected carbon steel exposed to natural KW seawater with biodiesel addition. However, the deepest pits were measured in biodiesel with PG seawater. Microbial sulfide production was stimulated in both seawaters by the presence of biodiesel either as a separate phase or as a fuel-in-water emulsion. The presence of seawater influenced the chemistry of the biodiesel, contributing both sulfur and chloride.
