Electrochemistry and corrosion behavior of different steels in ethanol-brine solutions Conference Paper uri icon


  • The increased use of denaturated and blended ethanol mixtures for different gasoline grades adversely affects the corrosion behavior of container materials in transportation applications. The transportation of Ethanol involves the use of steel storage tanks and loading/unloading racks prior to the blending process. The delivery of this bio-fuel mixture should take into consideration the integrity and reliability of the structures delivering this oxygenating additive. The impurities that are present in the blended ethanolic solutions, such as oxygen, chloride, water, and other chemical agents may either initiate or increase the steel corrosion rate, which makes the corrosion behavior of ferrous materials an important factor in the safe delivery or storage of this new vital blended fuel. This paper presents the results of the interfacial and kinetic studies of the dissolution process relevant to the corrosion of different steels (mainly APIX65 pipeline steel and AISI/SAE-Stainless Steel 416) exposed to the synergetic action of two impurities in ethanol, such as water and chloride. 2009 by NACE International.
