Free water in CO2 transport pipelines significantly increases corrosion risks, potentially leading to loss of containment within a year. Emitters typically dehydrate CO2 to prevent water dropout; however, operational upsets can introduce free water. This paper presents a comprehensive model that integrates thermodynamic and hydraulic simulators to predict water dropout locations, accumulation, and evaporation times. Such a model can support offline engineering studies and online operations, including corrosion risk estimation for corrosion models by providing corrosion estimates (Virtual Corrosion Coupons). The model's accuracy in predicting water behavior offers valuable insights for pipeline integrity management.
