Effect of Ethanol Blends and Batching Operations on Stress Corrosion Cracking of Carbon Steel

This project categorizes ethanol blends into three categories: blends that can be transported in existing pipelines without significant modification of the system and operations (Category 1), blends that require significant modifications (Category 2), and blends that cannot be transported in existing pipelines, but could be moved in specially designed systems (Category 3). The project develops data necessary to make engineering assessments of the feasibility of transporting fuel-grade ethanol (FGE) and FGE blends in existing pipelines in a batching or dedicated mode. The project determines the stress corrosion cracking susceptibility of steels in ethanol from different sources. The project develops an understanding of the factors that cause source to source to variation in the potency of ethanol towards corrosion and stress corrosion and cracking (SCC). The project identifies parameters that can be used to determine the degree of potency of a given source of ethanol in causing SCC for transportability decisions.
