Abstract

This study investigated the kinetics of CaCO₃ precipitation in the presence of Fe²⁺ at 70°C under anoxic conditions (1M NaCl, pH 6.00–6.03) using a flow-through system with carbon steel surfaces. The primary objectives were to assess the effect of varying Fe²⁺ concentrations on CaCO₃ precipitation rates, explore solid solution formation, and evaluate the role of mild steel corrosion in scale development. Findings indicated that Fe²⁺ had minimal influence on the precipitation rate but increased CaCO₃ solubility. Evidence suggests the formation of a CaxFe_1-xCO₃ solid solution. This study provides valuable insights into carbonate precipitation mechanisms in CO₂ corrosion, contributing to improved industrial scale management.
