Equilibrium conditions for the construction of the Pourbaix diagrams for iron-chromium alloys in lithium bromide absorption machines [Dataset]

Abstract

The dataset contains the data that have been obtained during the calculation of the equilibrium conditions used for the construction of the Pourbaix diagrams for iron-chromium alloys in the absence of and in the presence of lithium bromide (LiBr)/water (H2O) solutions with high concentrations (400-992 g/L) to simulate the aggressive conditions in the LiBr absorption machines. Equilibrium conditions for electrochemical and chemical reactions are calculated. The activity values of aqueous species considered are 10^–6, 10^–4, 10^–2 and 10^0. The bromide ion activities are 15.61, 194.77, 650.06 and 2042.65 and the water activities are 0.715, 0.358, 0.216 and 0.118, corresponding respectively to LiBr/H2O concentrations of 400, 700, 850 and 992 g/L at 25 ºC.
