Corrosion and fouling are unavoidable in chemical process operations, yet both can wreak havoc in many ways. If left unchecked, corrosion and fouling can negatively impact process operations, depress conversion rates and product yield, reduce energy efficiency. Meanwhile, corrosion-related damage, and fouling and buildup in process equipment, can lead to unscheduled downtime for maintenance, and in extreme cases, catastrophic failure of process equipment. All of this can create safety issues for plant personnel and neighboring communities, and reduce the overall profitability of the process.
This guidebook contains a collection of practical engineering articles related to corrosion-related issues in specific types of equipment, originally published in Chemical Engineering. Several articles focus on fouling and corrosion issues in aboveground and buried piping. Other articles provide practical guidance for managing and monitoring corrosion in pressure vessels and reactors, heaters, boilers, pumps, condensers, gas turbines and flares.
