In this interactive 30-minute webinar (+ unlimited time for Q&A), Colin Bateman, IGS Mission Critical Equipment Maintenance Expert, EMEA, will be sharing his 20+ years of experience in process vessel corrosion mitigation, focusing on caustic environments.

Colin will draw upon his experience with organic linings, weld overlay, and thermal spray protection, and will review case studies from the field as well as test data.

Presenter | Colin Bateman

Colin has 20+ years experience in specifying protective solutions to mission critical assets. He currently supports asset owners in Europe and Middle East, mitigating their erosion and corrosion issues.

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.

About HVTS

To protect against caustic corrosion and cracking, the High Velocity Thermal Spray (HVTS) technology has been tested and successfully deployed as a solution. Traditional alloys that have previously been used in thermal spray and overlay options, such as Monel and Hastelloy, exhibit possible porosity and failures in aggressive caustic conditions. However, IGS modified NiCrMo-XX alloys provide effective protection of the carbon steel substrates in aggressive caustic environments.
