Caustic Corrosion in High PH Vessels
Caustic conditions, within MEROX and other demercaptanization processes can rapidly attack steel's protective magnetite layer and cause material wastage. Following destruction of the protective magnetite layer, NaOH can additionally react with exposed elemental iron to form atomic hydrogen, leading to hydrogen embrittlement, decreased wall thickness, and caustic stress corrosion cracking (CSCC) or caustic embrittlement. These phenomena have led to multiple plant failures under different caustic conditions.

Corrosion Resistant Alloy (CRA)
To address these challenges, a robust, fit for purpose, field applied solution is required. This webinar presents a technology that has been highly successful in delivering long-term internal surface protection over the last 20 years. The webinar will explain how the technology was developed and functions, as well as presenting numerous documented case histories, from initial application to subsequent inspections.
