The corrosion rate of L-80 steel in seawater was investigated in the presence of corrosion, scale, and biocide inhibitors separately and in combination of each. Experiments were conducted using the rotating cylinder electrode method under autoclave conditions with rotational speeds of 1000 and 2000 rpm. The temperature of the autoclave was maintained at 80C, and CO2 was purged into the cell for 3 h. The corrosion rate of L-80 was determined by the LPR and gravimetric methods. Results indicated that the combination of scale-corrosion inhibitors and biocide-scale-corrosion inhibitors provided the best protection at both rotational speeds in relationship to blank conditions. Keywords: rotating cylinder electrode, seawater, and autoclave.

02276 WHY CORROSION INHIBITORS DO NOT PERFORM WELL IN SOME MULTIPHASE CONDITIONS: A MECHANISTIC STUDY

Results of inhibitor performance at slug flow in a 101.6 mm inner diameter horizontal pipeline. Electrochemical Impedance Spectroscopy (EIS) and scanning electrom microscope (SEM) techniques are used to reveal that the strong bubble impact, high shear stress and turbulent intensity are the reasons for a poor performance of inhibitor.

02274 EFFECTIVENESS OF CORROSION INHIBITORS IN RETARDING PROPAGATION OF LOCALISED CORROSION

In many service applications excursions in solution chemistry, temporary loss of inhibitor, or transient increases in temperature may give rise to localised corrosion. To test the return of inhibition when the loss is remedied, the use of an artificial pit has been investigated using simulations of cooling water and of of oil production formation water.
