In their natural state, LPG (Propane and Butane) and Natural Gas (Methane) are all odourless gases. The distinctive smell that people associate with these gases is actually added to them as a safety measure.
The most common odorant used with natural gas is tertiary butyl mercaptan (TBM). 5 The interior walls of steel pipe will chemically react with TBM to produce a disulfide product that is either less pungent than the original odorant or which lacks any odorant at all. 6 When a TBM molecule adheres to a pipe surface, the process is known as adsorption, and the adherence of the TBM to the surface prevents the odor from traveling downstream with the natural gas to which the molecule was ...
