The first editions of 'Corrosion Control in HF-alkylation units' by Henk Helle tackled the corrosion mechanisms and their mitigation. It was state-of-the-art, presenting a model for typical failure cases that could occur. At that time, it was among the few publications that comprehensively focused on this subject.

In response to public safety concerns regarding HF-alkylation units, the refinery industry took several steps. Major operators of HFA units collaborated to develop API Recommended Practice 751, "Safe Operation of HF Alkylation Units," which encapsulates the industry's best practices. Additionally, the two HFA technology licensors introduced various risk-mitigating designs, such as additive technology, minimum acid inventory, and the rapid acid-dump system. These, along with advancements like enhanced water spray systems and better HF-in-air detection, aim to minimize the consequences of an HF release following a failure.

While RP-751 provides detailed industry best practices, it falls short in discussing and explaining the corrosion mechanisms that compromise the integrity of an HFA unit. This book aims to fill that gap.

The current team of authors has thoroughly revised and updated 'Corrosion Control in HF-alkylation units'.  All chapters have been reviewed, expanded and reorganized to include new content and remove outdated material. New insights into the causes of failures have improved the clarity and consistency of the discussion on failure mechanisms and cases. Albert van den Bosch's extensive experience in the design, technology, and operation of HF Alkylation units was crucial in this aspect because in HFalkylation, corrosivity is predominantly the result of the way the unit is operated.  Thus, the book's title was changed to 'Integrity Management in HF Alkylation' to better reflect its wider scope, and several new chapters were added to cover the current risk-based approach to integrity management.

The book's goal is to provide a practical description of integrity management.
