Hydrogen Sulfide (H2S) finds extensive use as a fundamental ingredient in creating various sulfur-based compounds. The innovative hydrogen sulfide production process from JGC yields exceptionally pure H2S (with a purity of ≥99.9%) through the reaction of hydrogen and sulfur. This production facility boasts a compact design, prioritizing simplicity and safety for handling the highly toxic hydrogen sulfide. Furthermore, the process enables the easy generation of high-purity sodium hydrosulfide (NaSH aqueous solution) by reacting hydrogen sulfide with sodium hydroxide.
