Demonstration of the reliability of electrochemical methods for corrosion surveys in geothermy

Abstract

Electrochemical measurements for determination of corrosion velocity have been used in an experimental loop, placed in derivation on the exchanger of the geothermal plant of Fontainebleau (France). During several months, bench-scale experiments have been realized with untreated geothermal fluid with / without corrosion inhibitors on ring shaped samples separated by isolating rings. Redox potential, polarizing resistance and electrochemical impedance have been measured on the materials constituting the metallic rings (steel, stainless steel, Hastelloy C276, titanium). 9 Refs., 35 Figs., 4 Tabs.
