What are the Odorants used in Natural Gas to make it Detectable?

Have you ever wondered why natural gas smells differently from one place to another? While the mercaptan family compounds are the most used to odorize natural gas, other chemicals, and blends of compounds are developed to satisfy specific applications.

Odorization Background

In earlier posts, we share that the government requires natural gas be odorized as a safety measure since it is combustible and odorless. We also discuss that odorant is introduced by either chemical vaporization or chemical injection. We further share the advantages and disadvantages of various odorization systems, whether wick-type, bypass, pulse bypass, drip injection or pump injection systems.

What is the odorant added to natural gas to make it smell?

As the manufacturer of natural gas odorizers, we are frequently asked, “What is the chemical added to natural gas to make it smell?”
