Study of the corrosion of metals in liquids found in biorefineries and in ionic liquids

Abstract : Biorefineries of the future should be an essential tool for the bio-sourced economy. Understanding the corrosion phenomena in these new installations is essential due to economical and environmental potential aspects. Developing fast running screening tests to evaluate the corrosion rates of various compounds (organic acids or ionic liquids) potentially contributing to corrosive environments on various metals used in adavanced biorefinery pieces of equipment could be strategic to reduce investment and operational maintenance costs and also, increase safety and limit environmental impact from non controlled emissions. This study showed that the regulatory test Cl from CLP is not really adapted to the tested products. It showed that the classification of a product could be different due to experimental duration choice. The innovating IO-LI-TEC screening method could be adapted to study the corrosivity of ionic liquids. It was showed that the influence of impurities was significant. The use of the classical amperometry studies could be helpful to study the behavior of different metals in products from biorefineries.
