GEO-COAT Webinar: Material characterisation and testing of coatings for corrosion challenges in high-temperature geothermal power production

The Geo-Coat consortium invites you to its 2nd webinar on mitigating the corrosion challenges in aggressive geothermal environments – “Material characterisation and testing of coatings for corrosion challenges in high-temperature geothermal power production” on 21st October, 13:00 UK time

Materials used in high-temperature geothermal wells and equipment that are in direct contact with the geothermal fluid can be subjected to corrosion, which can result in high costs associated with materials, labour, and production efficiency of the well. The corrosion aggressiveness of geothermal fluids depends on the chemical composition and physical character of the fluid, e.g., acidity (pH) and the exploitation parameters such as temperature, pressure, and flow rate. The main corrosive agents in the geothermal fluid are the dissolved gasses H2S, CO2 and chloride ions. In some geothermal systems, HCl gas is present, and condensation and re-boiling can cause localised enrichment of hydrochloric acid and, consequently, severe corrosion of materials in the systems. Various components and equipment used in the production of geothermal power from high-temperature geothermal fields can experience different corrosion attacks as well as wear and erosion.

An overview of tribological and corrosion laboratory tests and microstructural analysis will be presented for different novel coatings systems developed for various components of the high-temperature geothermal power production system. Following a discussion on what future development of coating materials is needed for the advancement, safe operation, and increased efficiency of geothermal power production in the world.
