About hydrogen sulfide gas and corrosion.
Even low concentrations of hydrogen sulfide gas can have a significant impact on equipment. Corrosion can lead to failures at the contact points of the equipment.
Hydrogen sulfide gas is highly toxic, and concentrations of hydrogen sulfide gas above 10 ppm can lead to a diminished sense of smell, with headaches and nausea potentially occurring quickly. At high concentrations around 800 ppm, the risk of acute poisoning increases, and the possibility of death arises. However, even at low concentrations of hydrogen sulfide gas at the ppb (0.05 ppm) level, which have no impact on the human body, the effects on equipment can be significant. According to ISA standards, gas management for electrical control equipment is required to be below 50 ppb. Machinery is more vulnerable to hydrogen sulfide gas than humans, necessitating strict management.
basic information
Hydrogen sulfide gas must be managed at a gas concentration of 50 ppb or lower. In places where hydrogen sulfide gas is likely to occur, such as paper mills, sewage treatment plants, and geothermal power plants, daily efforts are made to manage the gas.
