Determination of corrosion monitoring frequency!
Corrosion monitoring can be conducted either periodically or continuously, with the monitoring frequency being influenced by the chosen monitoring technique, the extent of corrosion on the target component, and the associated monitoring expenses. The corrosion monitoring approach dictates the speed at which corrosion rates can be assessed. For instance, while corrosion coupons typically necessitate monitoring intervals exceeding a month, resistance probes can offer more frequent readings, ranging from hours to days.
Moreover, it is advisable to escalate the monitoring frequency as corrosion levels intensify, while scaling back on monitoring for components exhibiting milder corrosion. The financial aspect of corrosion monitoring holds significant weight for refineries. Overusing high-cost monitoring techniques can result in substantial expenses. Presently, continuous online corrosion monitoring tends to be more expensive than periodic monitoring. Consequently, refineries commonly opt for periodic monitoring methods and strive to minimize monitoring frequencies wherever feasible.
