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.
