Weak gases comprise a variety of corrosive chemical substances. In addition, combinations of these substances can lead to unexpected corrosion problems. The challenge was to identify potential corrosion problems in existing equipment and recommend material for both existing and new equipment.


We analyzed the critical parts of the ventilation system, summarized the potential corrosion probability, and recommended material for each part. Our analysis and recommendations were based on process data, previous experience, and available materials data.
