Abstract
Corrosion rate results from a 720 hours exposure period to geothermal brine acidified to pH4 are discussed in this paper. The corrosion tests were performed in a four stage flash system so that results obtained at different temperatures could be compared. Carbon steel and alternate construction materials were used as test specimens. Results indicate that carbon steel corrodes excessively (more than 50 mils/year) at temperatures above 150°C. Alternate construction materials (alloy steels) may be utilized under these conditions.
