| Summary: |
Transport from the C02 source to the storage area is a key element in all carbon
dioxide capture and sequestration systems, with pipelines being the logical and
preferred transportation methods. Initial research indicates that a low-purity C02
poses a significant durability risk to oil and gas pipelines. If the water content of a
C02 stream is above the solubility limit then a separate aqueous phase will exist. This
aqueous phase can induce corrosion depending on its form and chemical composition.
However, there exist a limited number of studies on the C02 corrosion inhibition of
carbon steel transporting C02 saturated water in high pressure environment. The
objective of this work is to elucidate the C02 corrosion inhibition effect of
imidazoline and imidazoline added-thiosulfate as new inhibitors for X52 steel in C02
saturated water at different high pressures using electrochemical techniques such as
linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS)
and potentiodynamic polarization sweep. |
