Sodium hydrosulfide is mainly used in medicine, mineral processing, fuel, tanning and organic synthesis industries. Sodium thiohydride is the raw material for the manufacture of ammonium sulfide and pesticide semi-products in the pesticide industry, sodium thiohydride is widely used in copper ore dressing in the mining industry, and it is also used as an auxiliary agent for the preparation of sulfide fuel and as an organic intermediate in the dye industry.

Leather used in leather industry. It is also used in wastewater treatment and chemical fertilizer industry to remove monomer sulfur from activated carbon desulfurizer. In the Yangtze river delta region, there are more fuel plants, tanneries and agricultural and pharmaceutical plants, and there is a greater market demand for sodium hydrosulfide.

It can be seen that this method can recover hydrogen sulfide from acidic gas with a large profit margin, protect the environment and obtain economic benefits at the same time. Acid gas recovery sodium hydrogen sulfide process, the process is relatively simple, investment, reliable, no secondary pollution, with economic benefits, but also has good social benefits, the realization of refinery acid gas resource utilization.
