Abstract

In this work, a proposal based on the fractal and multifractal analysis of electrochemical noise (EN) to corrosion evaluation in A36 steel and AISI 304 stainless steel, exposed in aqueous solutions of monoethanolamine (MEA) with carbon dioxide (CO2), is presented. Time-series of potential and current captured during the corrosion process of both steels exposed to different conditions of temperature and MEA concentration were analyzed using the rescaled range (R/S) method. The R/S analysis identified three characteristic regions that suggest that the time-series contain information associated with different physical phenomena in the corrosion process, that could be related to transport mechanisms and chemical reactions. The Hurst exponents calculated allow identifying correlations associated with the type and degree of corrosion, as well as information on the corrosion mechanisms of both steels evaluated. Hence, the Hurst exponent calculated from potential and current time-series could be used as an inexpensive and easily implemented tool for rapid diagnosis of the corrosive effects in the steel equipment used in the absorption processes of CO2 capture with amines.
