Iron Corrosion Inhibition in Acidic, Highly Saline Geothermal Water

摘要

An effective inhibitor of iron corrosion in acidic(pH 3.7), highly saline (ca. 150 g/l) thermal groundwater fromWest-Lithuania aquifers was found. The inhibition mixture studiedconsisted of a siliconorganic compound and diethylene ether.Corrosion rates were determined at different inhibitorconcentration, solution pH, immersion time, and solutiontemperature. A degree of protection of up to 90 percent wasobserved when additive concentration reached ca. 0.3 g/l. Thecorrosion inhibition was predominantly due to the hindering of theanodic half-reaction.
