Odorising/Dosing Service
Orbital Gas Systems pioneered the transition of UK gas networks, from national odorisation to regional. This enabled exporting unodorised natural gas to Europe, achieved by installing 126 odorisation plants at each gas network offtake throughout the UK. We provide systems that enable odorant injection for a range of gases including biomethane/renewable natural gas (RNG), liquified petroleum gas (LPG), hydrogen, and CO2. Odorisation is the process of adding THT or Mercaptan blends (such as TBM, DMS, or other types of odorants), to gas or liquid to ensure it is readily detectable to the human nose, which is critical for safe gas consumption.
Odorisation is a key safety aspect in low pressure provision of natural gas in domestic networks, but it also provides a convenient method of sulphur dosing, which inhibits corrosion of parts and pipework.
