Sulfide application field

ndustrial production

In the field of industrial production, hydrogen sulfide is mainly used to produce sulfur and sulfuric acid, which is an indispensable raw material in many industrial processes. For example, sulfur can be recycled from hydrogen sulfide through the Claus process. This process is particularly important in refining plants and natural gas treatment to reduce environmental emissions. Sulfuric acid is produced by contacting the process. Among them, hydrogen sulfide is first converted into sulfur, and then sulfur burning produces sulfur dioxide and then converts into sulfuric acid. Sulfuric acid is one of the largest chemical products in the world, and is widely referenced in the fields of fertilizer, chemical synthesis and mineral processing.

Environmental governance

The application of hydrogen sulfide in environmental governance is mainly reflected in its role in wastewater treatment and gas purification technology. In wastewater treatment, hydrogen sulfide can be converted into non -toxic sulfides through chemical precipitation, thereby reducing pollution to water bodies. In addition, hydrogen sulfide also plays an important role in gas purification, especially in the process of oil refining and natural gas treatment. It is removed by using an absorbent or catalyst to meet the environmental standards and improve product quality. For example, in heavy metal detection, hydrogen sulfide can be used to generate unable to accumulate into the difficulty of sulfide, thereby achieving the qualitative and quantitative analysis of heavy metal ions, lead, mercury.
