Wet H2S damage, high temperature sulfidic corrosion and acid dewpoint corrosion are aggressive damage mechanisms affecting sulfur recovery plants. The purpose of the sulfur recovery plant is to convert H2S into sulfur, a saleable by-product.

It also eliminates the release of H2S to the atmosphere. Any failure or leak in these processing plants could lead to a safety incident due to processed services and process parameters. This study has evaluated the most relevant damage mechanisms and reviewed historical corrosion damage and inspection history associated with major equipment. Deterioration of refractory linings caused by poor design/installation, overheating, thermal shock and chemical attack has also been considered as a chronic challenge.

This paper has set several steps to control corrosion and deterioration on these Sulfur Recovery Plants. Controls include material selection, process parameters (Plant Integrity Windows), refractory design and inspection / monitoring techniques.
