In CO2 corrosion, precipitation of iron carbonate can significantly reduce the corrosion rate of the underlying steel. Precipitation rate depends on a reliable calculation of the iron carbonate solubility limit. The open literature does not provide an expression for iron carbonate solubility that covers a wide enough range of parameters. In this study a Unified iron carbonate solubility (K-sp in mol(2)/L-2) expression is developed based on the literature data: logK(sp) = -59.3498 - 0.041377T(k) - 2.1963/T-k + 24.5724 log(T-k) + 2.518l(0.5) - 0.657l which accounts for both temperature and ionic strength effects. The predictions made with this unified equation agree well with the published experimental data. (C) 2009 Published by Elsevier Ltd.
