The effects of oil viscosity on sweet corrosion in multiphase oil/water/gas horizontal pipelines
- Ohio Univ., Athens, OH (United States)
Experiments were carried out in a 10 cm I.D., three phase oil/water/gas horizontal Plexiglass pipeline. Mixtures of salt water with oils of viscosities 2 cp and 96 cp ranging from 0% to 100% off were used for the liquid phase with carbon dioxide as the gas phase. Results indicate that, for both full pipe flow and slug flow, at each water percentage up to approximately 60%, the corrosion rate increased with off viscosity at each flow condition. Above 60% water, the corrosion rate decreased rapidly to negligible values. In slug flow, the corrosion rate increased with increase in Froude number. This may be attributed to presence of gas at the bottom of the pipe and the higher pressure drops across the slug front at each Froude number.
