Researchers address ethanol’s corrosive impact so that it can be piped in existing network [Registered]

One of the main disadvantages of ethanol is that because of its corrosive nature, it cannot be transported in existing pipeline network. Researchers from Ohio State University and Det Norske Veritas have addressed the means to overcoming this problem. “One of the most important concerns with regard to the integrity of pipelines and tanks is the propensity of ethanol at concentrations above 20 volume percent in gasoline to cause cracking of steel,” explains Narasi Sridhar, vice president, director of the materials program at Det Norske Veritas. “This phenomenon is called stress corrosion cracking.” The Pipeline Research Council International, a consortium…
