There could be several reasons =E2=80=93 you need to 1) understand where the material is coming from =E2=80=93 is it from a tank, natural gas feed line, etc.=C2=A0 2) Depending upon the feed may impact when the odorant is put into the supply.=C2=A0 Finally =E2=80=93 you need to see if there is a reaction taking place somewhere =E2=80=93 the mercaptan is a sulfur chemical and can form a number of compounds =E2=80=93 such as iron sulfides, react with other metals and the like.=C2=A0

Subject: [DCHAS-L] Mercaptan in Gas Suppy
Has anyone encountered the situation where the odorant smell from the burner gas supply changed when the gas was not used for several months? If so, any explanation why?
The individual who posed this question to me said that his "lost its rotten smell and now smells slightly musty and is much less noticeable".
Thanks ... Jim
