Gas pollutant emissions

Based on the different iron and steel producing processes, there is a wide range of pollutants in a steel plant’s off-gas systems. Some are based on organic chemicals (i.e. carbon and hydrogen based), while others are of a more metallic origin (such as mercury). Monitoring these pollutants requires customized gas analyzer solutions where the sensors fit the gas matrix and the specific compounds to be monitored. The level of gas emissions and the measuring range both play important roles in selecting which gas analyzer system to use.
