What mercaptan is in natural gas?
While the odorant often contains mercaptan, it is not always the case. The odorant is typically a blend of various organosulfur or non-sulfur compounds. It is customary that odorants for natural gas may include tertiary butyl mercaptan, tetrahydrothiophene, isopropyl mercaptan, dimethyl sulfide, and methyl ethyl sulfide.
