Background

The natural gas is combustible gas formed by ancient living beings buried underground under the action of high temperature and high pressure for billions of years, and is colorless, tasteless, nontoxic, high in heat value, stable in combustion, clean and environment-friendly. The main component of the natural gas is methane, and the gas tetrahydrothiophene with foul smell is added into the natural gas, so that gas leakage can be found in time, and accidents such as poisoning, explosion and the like can be prevented. Malodorous gases are known as odorants, and typical odorants use tetrahydrothiophene, which is an organic compound or mixture of strong odors. When added to gas at very low concentrations, the gas is given a distinctive, unpleasant warning odor so that the leaking gas is readily detectable when it reaches its lower explosive limit of 5% or a harmful concentration acceptable to humans.
