What water content constitutes wet hydrogen sulfide?
Thread Content
Dry hydrogen sulfide has no corrosive effect on steel; hydrogen sulfide is only corrosive when it is dissolved in water. Dear sea friends, what level of water content constitutes wet hydrogen sulfide? We can’t count every single drop of water, right?
There is no unified standard for the water content in wet hydrogen sulfide, but it is generally considered that wet hydrogen sulfide exists when the concentration of hydrogen sulfide dissolved in water exceeds saturation. Furthermore, factors such as humidity and temperature also have varying effects on hydrogen sulfide corrosion. Therefore, experiments and tests are still required for specific cases to determine whether it should be considered wet hydrogen sulfide. .
Water content is an important factor in determining whether hydrogen sulfide is wet hydrogen sulfide. Generally speaking, if the water content of hydrogen sulfide is greater than 50 ppm (that is, one part per million), it can be considered wet hydrogen sulfide. When hydrogen sulfide dissolves in water, it easily creates an acidic environment, which leads to the corrosion of metal materials (such as steel). Therefore, in certain industries, strict monitoring and control of hydrogen sulfide-containing environments are necessary to ensure the safety of equipment and workers. In short, it is necessary to determine whether hydrogen sulfide is wet hydrogen sulfide based on specific circumstances; one cannot simply use the water content as a criterion
