文摘
The influence of sweet crude oil on calcareous scale deposition under cathodic protection of carbon steel in artificial seawater was investigated using chronoamperometry, electrochemical impedance spectroscopy, scanning electron microscope/energy-dispersive spectroscopy, x-ray diffraction and Raman spectroscopy. In the presence of crude oil, calcareous deposit formation is influenced in terms of both kinetic and nucleation mostly in high volume concentrations. It is indicated that the CaCO3 deposition is hindered by absorption of active surface compounds present in oil on to the surface mainly due to strong covalent bonding of aromatic compounds.
