Gas leak detection: what is the science behind gas odorization?
As experts in the field of gas odorization, our Arkema Thiochemicals team has written an article exploring the science and regulatory requirements behind this process, as well as the various challenges that can arise.
In this article, we aim to provide a comprehensive overview of gas odorization expertise, covering everything from:
- the types of gas odorants used and the challenges associated with implementing odorization systems effectively,
- practical advice and recommendations for odorization system design, operation, and maintenance,
- insights about how gas odorization is evolving with the emergence of CCS (carbon capture and storage), CO2 odorization, and hydrogen technologies. (bien mettre le 2 de CO2 en indice).
Arkema: the most innovative gas odorant supplier
- Vigileak® Z can be used when minimized fuel sulfur content is required.
- Codetect® can be used for industrial gases where CO toxicity risk is to be monitored.

Specific safety issue - Odor fade
Be aware that the odorant chemical added to gas to make it detectable may not warn of a gas leak or the presence of gas to all persons in every situation.
Situations where the odorant in an odorized gas may be undetectable include:
- Odor intensity may fade or be eliminated for a variety of chemical and physical causes, including the oxidation of odorant (mercaptans) on iron oxyde, adsorption onto the internal surface of pipes or appliances, or absorption into condensates.
- Contact with soil in case of underground leakages may de-odorize or remove odorant from the gas
- Some people have a diminished ability, or inability to smell the stench of those odorants (anosmia). Factors that negatively affect a person’s sense of smell include age, gender, medical conditions, and alcohol/tobacco usage
- The stench of odorized gas may not awaken sleeping persons
- Other odors may mask or hide the stench. ( unusual impurity profiles from biogas or shale gas)
- Olfactory adaptation or olfactory fatigue, when the exposure to the odorant lasts and person gets used to this level of intensity.
Ask us for educational support to educate yourself, your employees, and your customers with the content of this warning and other important facts associated with the so-called “odor-fade phenomenon."
