The concept of using physics-based models for corrosion monitoring is still new although corrosion monitoring by use of hardware coupons and probes is well recognized. This paper describes the application in downstream related to crude unit overhead and demonstrates how the monitoring concept can be used and its benefits.
The corrosion process of carbon steel in the presence of silica sand deposit in chloride-containing solution at 30 °C was monitored by use of electrochemical noise (EN). Results demonstrated that electrochemical noise with recurrence quantification analysis is useful for monitoring localized under deposit corrosion.
All Zero-voltage ammeters, including the zero-resistance ammeter or the shunt-resistance ammeter, impose a small voltage between each of the electrodes and the coupling joint. An experiment studied the effect of the voltage imposed on the measured corrosion currents using a CMAS probe. Experimental results.
The goal of this compilation is to educate the reader through experiences and observations from real-world applications and to provide tools for the identification and remediation of pipeline corrosion issues before failure. Pipelines have been used to transport fuels since the 19th century. While there is no clear consensus of the total number of pipeline miles in use throughout the world, most agree that the U.S. has over 2.5 million mi of energy pipelines. This book provide tools for the identification and remediation of pipeline corrosion issues before failure.

The use of corrosion sensors for remote monitoring of infrastructure assets has become more frequent in recent years. Corrosion sensors utilizing the electrical resistance (ER) method have been developed, in which the resistance of a test sample is used to infer thickness change and hence corrosion rate. ER corrosion sensors have been deployed on various structures including marine wharves, bridges and coal processing facilities. On some marine wharf structures and some marine coastal bridges the performance of jacketed petrolatum-based tape wrapping systems on steel piles has been assessed including on steel piles suffering from accelerated low water corrosion (ALWC) and microbiologically influenced corrosion (MIC). The paper provides some relevant discussion of the corrosion and its mechanisms prevalent to marine wharf and bridge steel piles in Eastern Australia, Southern Australia and Western Australia as well as the pile wrapping/jacketing systems installed and being performance monitored in-situ. Details are provided of the corrosion sensors. An assessment of the results obtained to-date for up to 3 years of in-situ exposure has been made.
