H2S
Control of hazardous gases: H2S

H2S occurs as a corrosive, toxic and explosive side product in the petrochemical industry. Continuous monitoring of this hazardous compound is critical to avoid corrosion of natural gas pipelines and ensure workers safety. Real-time analysis is essential to guarantee that burning fuels are H2S clean in order to prevent acid rains.
