Hydrogen sulphide | WorkSafe

H2S gas is often encountered in large amounts in geothermal areas in New Zealand. Upon reaching the surface, most of the hydrogen sulphide is released from the geothermal fluid along with steam at boiling temperature. At lower temperatures, much of the H2S gas remains dissolved in the geothermal fluid. Where geothermal energy is used, H2S gas is removed from the geothermal fluid and is vented ...
