Odorization of natural gas is an important operational aspect in the natural gas industry. Since natural gas is odourless, a gas leakage cannot be detected unless sufficient odorant is added to it. On the other hand, if too much odorant is used, even harmless small leakages will be noticed, leading to unnecessary reports from worried customers or end users in private households and industry.
A widely-used odorant for natural gas is THT (tetrahydrothiophene). THT is a sulphur-containing liquid with a strong, unpleasant smell. If added in small quantities to natural gas, THT gives the gas the odour required for safe use in both households and industry.
Since there are specified limit values for the minimum and maximum concentrations of THT in natural gas, these must be measured. These measurements often only mean laboratory checks at certain intervals. Using our equipment, it is also possible to measure THT concentrations online, ensuring continuous verification and thus additional safety. As the reference value is continuously updated, adding too much THT is avoided, which results in cost reductions.
