The paper summarizes the results of analysis and field measurements performed for assessing the water corrosivity in a geothermal plant. Corrosion rates were measured on carbon steel, in an aqueduct used for conveying CO2 containing water with moderate salinity, from production wells to reinjection wells in order to sustain vapor production of the geothermal field. The results were collected under different operating conditions. The corrosion rate was evaluated by means of linear polarization tests and weight loss tests as a function of flow rate, pressure, temperature, pH, oxygen and carbon dioxide content. The experimental results were discussed by considering models available in literature for predicting CO2 corrosion.

Abstract
The paper summarizes the results of analysis and field measurements performed for assessing the water corrosivity in a geothermal plant. Corrosion rates were measured on carbon steel, in an aqueduct used for conveying CO2 containing water with moderate salinity, from production wells to reinjection wells in order to sustain vapor production of the geothermal field. The results were collected under different operating conditions. The corrosion rate was evaluated by means of linear polarization tests and weight loss tests as a function of flow rate, pressure, temperature, pH, oxygen and carbon dioxide content. The experimental results were discussed by considering models available in literature for predicting CO2 corrosion.Pubblicazioni consigliate
