Basics

• A Chemical used to add a scent to various Compressed Gasses (Typically Methane or Propane / LPG )
• Thus when there is a leak one can detect the smell and respond accordingly
• Various Compounds Are Used, but the main ones are:
  • Methanethiol (Common in Methane (aka "Natural Gas" ; CNG ) )
  • Ethanethiol (Common in Propane / LPG )
    • The Following can also be used (or blended with eachother and/or the odorants listed above)
      • Dimethyl Sulfide
      • Isopropyl Mercaptan (aka Isopropanethiol )
      • Methyl Ethyl Sulfide
      • Normal Propyl Mercaptan (aka Propanethiol )
      • Secondary Butyl Mercaptan (aka 2-Butanethiol )
      • Tertiary Butyl Mercaptan (aka tert-Butylthiol )
      • Tetrahydrothiophene
