Description
Minimizing Fouling and Corrosion — Volume 2: Improved Processes and Practices
The fight against corrosion and fouling is a never-ending battle for process operators throughout the chemical process industries (CPI). The articles in this Chemical Engineering Guidebook provide a wealth of practical engineering recommendations and best practices for effective corrosion monitoring and prevention in various types of CPI equipment components and systems.
Several topics focus on troubleshooting and inspection as well as provide tips for identifying and rectifying corrosion-related issues during plant revamps.
Articles center on selecting the most appropriate material of construction to withstand exposure to corrosive media. Also provided are tips for proper selection, handling and storage of acids, addressing fouling- and corrosion-related issues in cooling towers, filtration systems, wastewater-treatment plants and more.
This volume shares a wealth of maintenance, risk-reduction and reliability strategies.
