What do they Odorize natural gas with?
What are gas odorants? The gas odorant is the chemical injected into the gas to cause it to smell. Most odorants today consist of an assortment of various chemicals which include tertiary butyl mercaptan, tetrahydrothiophene, isopropyl mercaptan, dimethyl sulfide, and methyl ethyl sulfide.
Does mercaptan contain sulfur?
Mercaptans are the organic components of hydrocarbons with sulfur; they also have a bad smell and corrosive properties in pipeline transmission.
Why is sulfur added to natural gas?
Mercaptan, a harmless chemical, gives gas its distinctive rotten egg odor. It is added to natural gas to make it quickly recognizable and to prevent accidents like this from happening.

What are the levels of mercaptan in natural gas?
A. The simple answer is that mercaptan is not harmful at the levels used when odorizing natural gas. The nose can detect mercaptan at a 1.6 PPB (parts per billion), and the typical range of odorants in natural gas ranges from 0-10 ppm (parts per million).
What kind of odorants are used in natural gas?
It is customary that odorants for natural gas may include tertiary butyl mercaptan, tetrahydrothiophene, isopropyl mercaptan, dimethyl sulfide, and methyl ethyl sulfide. What is the smell in gas? Natural gas in its native state is odorless.

What is the purpose of natural gas odorization?
Gas odorization is the process of injecting an odorant into a gas stream by an odorizer or odorant injection equipment. The purpose, of course, is to make the gas smell to detect it, because, in its natural state, natural gas is odorless. What mercaptan is in natural gas? While the odorant often contains mercaptan, it is not always the case.
