Abstract:

Pipeline companies have a keen interest in assessing the feasibility of transporting fuel grade ethanol (FGE) and ethanol blends in existing pipelines. A 2003 survey of industry, reported in API Technical Report 939-D (2nd edition), indicates that stress corrosion cracking (SCC) has been observed primarily in user terminals exposed to ethanol products, but not in ethanol producer tanks, rail/tank car/shipping transportation, nor end-user systems (e.g., gas tanks). More recently, a short segment of pipeline transporting FGE in North America was reported to have suffered SCC. In contrast, Brazil, which has transported anhydrous and hydrous ethanol for many years, has not reported any SCC in their pipeline system. At present, there is an incomplete understanding of why the occurrence of SCC differs so significantly in different parts of the supply chain. Monitoring some of the factors that affect SCC, dissolved oxygen and corrosion potential, may lead to a better understanding of SCC risks.
