Abstract

The purpose of this paper is to present the impact of improper choice of procedure for repairing a pressure vessel for methanol storage, that could finally lead to failure. Presented information is based on the results of inspection activities from an oil and gas plant. Anyhow, these types of problems can appear in industrial units treating, or using methanol for various purposes, especially in cases when residual stresses are significant enough to cause damage mechanisms and create cracks on pressure vessels or pipelines.

Keywords: pressure vessel, integrity, methanol, stress corrosion cracking
