Main Objective

The Colorado School of Mines (CSM), in association with the National Institute of Standards & Technology (NIST), proposes a three-year research program to measure the effect of concentration and temperature of ethanol in fuel blends on microbiological and caustic corrosion of high strength steels used in handling and transportation. The project will also determine tested solutions for identified corrosion problems while transporting ethanol-fuel blends.

Public Abstract

The Colorado School of Mines (CSM), in association with the National Institute of Standards & Technology (NIST), University of Colorado, Steel Tank Institute, XcelEnergy, El Paso Corporation, Merrick and Company, and British Petroleum will team for a three-year research program to measure the effect of concentration (including oxygen and other gaseous products) and temperature of ethanol in fuel blends on microbiological and stress corrosion cracking of pipeline steels used in storage and transportation. The project will also determine tested solutions for identified corrosion problems while transporting ethanol-fuel blends. The proposed work will include corrosion, microbiological influenced corrosion, and ethanol stress corrosion cracking efforts.
