Abstract
Systems and methods for evaluating the corrosion risk in operations with equipment for the handling an acid gas-containing solutes, e.g., an amine unit for the removal of acid gases such as HS, CO, etc., are provided. Input parameter values corresponding to geometrical parameters of at least an equipment (or a portion of an equipment) susceptible to corrosion risk, operating parameters, fluid dynamic properties, and properties of the solute are received by the system. Based on the input values, the systems and methods derive a minimum pressure above which acid gas flashing occurs given the localized pressure drop, causing corrosion in the identified location. In one embodiment, the systems and methods provide an assessment correlating acid gas loadings with the corrosion risk.
