Description
Corrosion and fouling can wreak havoc in many chemical process operations, and can negatively impact process operations, depress chemical-conversion rates and product yield, reduce energy efficiency and incur excess costs associated with maintenance and repairs. Meanwhile, corrosion-related damage, and uncontrolled fouling or 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 Chemical Engineering Guidebook contains practical engineering articles related to corrosion-related issues in specific types of equipment. The articles were originally published in Chemical Engineering from 2010 to 2018. Several articles provide practical guidance for managing and monitoring corrosion in pressure vessels and reactors, heaters, boilers, pumps, condensers, gas turbines, flares and more. Others focus on fouling and corrosion issues in aboveground and buried piping and storage tanks.
This guidebook is 198 and delivered in a PDF format.
