Audited Supplier What is Sodium Hydrosulfide ?
Sodium hydrosulfide is used in the dye industry for synthetic organic intermediates and preparation of sulfide dyes, in the leather industry for raw skin hair removal and tanning, in the fertilizer industry for removing activated carbon desulfurizer monomer sulfur, in the mining industry for copper ore dressing, in the production of artificial fiber for sulfite dyeing, is the manufacturing of ammonium sulfide and pesticide ethyl mercaptan semi-finished raw materials, Also used for wastewater treatment and so on. The production technology of sodium hydride sulfide is relatively mature, but with the development of various economic forms and the increasingly fierce competition, it is required to reduce the input as much as possible to produce high quality and more products.
At present, the preparation method of sodium hydride sulfide is caustic soda absorption method, which requires the raw material gas to be relatively pure hydrogen sulfide gas. Sodium hydride sulfide is mainly produced by the reaction of the tail gas of the production of barium chloride or barium nitrate and sodium hydroxide solution. The production of sodium hydride sulfide by caustic soda method requires no carbon dioxide in the raw gas. If the raw gas contains carbon dioxide, sodium carbonate will be generated in the production process: NaOH+CO2→Na2CO3+H2O, the generation of sodium carbonate not only reduces the yield of caustic soda, but also affects the quality of sodium sulfide hydride, affecting the use of users, carbon dioxide content is greater than 10%, in production will also block equipment and pipelines, so that production can not proceed normally.
