Description
CO2 corrosion analysis using the de Waard-Milliams correlation. Calculates corrosion rate, severity classification, inhibited rate, and required corrosion allowance for carbon steel pipelines.
Parameters:
- P: Total pressure (psia)
- yCO2: CO2 mole fraction in gas (0-1)
- T: Temperature (°F)
- inhibitor_eff: Inhibitor efficiency (0-1)
- design_life: Design life (years)
