Abstract Details

2013, Doctor of Philosophy (PhD), Ohio University, Chemical Engineering (Engineering and Technology).
Understanding the mechanisms that lead to localized corrosion in oil and gas pipeline is of great interest to corrosion engineers worldwide. The objective of this study is to examine the phenomena of localized corrosion in upstream oil and gas industry pipelines which operate under slightly sour conditions due to an H2S/CO2 environment. Experimental studies have been carried out to identify the parameters with the most influence on the likelihood of localized corrosion. It is shown that the solution bulk pH, concentrations of carbonates, concentration of sulfides, and the ionic strength of the solution are the major factors for localized corrosion. The flow temperature, and saturation values for both iron sulfide and iron carbonate were also identified as important parameters affecting the corrosion process. The experimental data were then analyzed and used to develop a correlation to relate these parameters to the likelihood of localized corrosion in mild steel pipelines.
