CORROSION INHIBITION PERFORMANCE BY OCTYLMETHYLIMIDAZOLIUM- BROMIDE OMIBr ON API 5L X52 STEEL IN 1.0M H2SO4

In this study, Ionic Liquid Octyl-Methylimidazolium-Bromide OMIBr will be tested
as corrosion inhibitor in 1.0M solution of sulfuric acid (H2SO4) on API 5L X52 using
linear polarization method and electrochemical impedance method at temperatures
30◦, 50◦, and 70◦. From Linear Polarization method and Electrochemical Impedance
spectroscopy, the polarization resistance and charge transfer resistance increases with
injection of OMIBr which confirms the inhibition effect of OMIBr. From
electrochemical test, the inhibition efficiency of OMIBr on API 5L x52 in 1.0M H2SO4
has been found to decrease with increasing temperature
