High-Purity Hydrogen Sulfide Production Process

For better and safer production

Hydrogen Sulfide (H2S) is widely used as raw material for synthesis of a number of sulfur-containing compounds.
JGC hydrogen sulfide production process produces high-purity (≧99.9%) H2S by the reaction of hydrogen and sulfur. The production plant is compact and ensures easy and safe operation for the production of highly toxic hydrogen sulfide.
High-purity sodium hydrosulfide (NaSH aqueous solution) is also easily produced by the reaction between hydrogen sulfide and sodium hydroxide.
