    Effect of calcium carbonate on low carbon steel corrosion .

    Low carbon steel corrosion was investigated over time in CO 2-rich brine with and without CaCO 3.. The average corrosion rate was lower in presence of CaCO 3.. The scales were thinner and more porous in case of adding CaCO 3.. A mixed carbonate (Fe x Ca 1−x CO 3) is formed with CaCO 3.. The Fe x Ca 1−x CO 3 scales exhibited lower E corr and I corr, and higher anodic polarization resistance.

    However, calcium carbonate is more likely to affect the flavor than potassium carbonate, and may take a few months to fully precipitate. One-quarter ounce (about 4 teaspoons) of calcium carbonate reduces acidity in one gallon by about 0.25%. Foaming may occur because of the production of CO2. Do not use more than one ounce per gallon.
