Sodium bisulfide
The production process of sodium hydrosulfide is relatively well-established. However, with the development of diverse economic structures and increasingly intense competition, there is a growing demand to minimize input costs while producing higher-quality and larger quantities of products. We have conducted further research into the production process of sodium hydrosulfide, particularly exploring and improving two aspects: replacing water-ring vacuum pump systems with water-jet vacuum pump systems, and substituting once-through well water with circulating water in the hydrogen sulfide absorption system. These improvements have yielded significant economic benefits.
