Materials Testing at the Vernal, Utah Tar Sands Liquefaction Site

摘要

General corrosion and U-bend and C-ring stress corrosion specimens were exposed in the product line at the Laramie Energy Technology Center's Vernal, Utah in situ tar sands liquefaction site. This test utilized steam injection to liquefy the entrapped bitumen which was then pumped to storage tanks. General corrosion resulting from exposure to these particular test conditions was negligible, with only the ferritic-steel specimens showing measurable corrosion. There was no indication of severe localized attack in the form of pitting or intergranular corrosion, no indication of stress corrosion cracking on any of the materials exposed, nor indication of any mineral particles in the product which would serve as a source of erosion.
