Natural gas is colorless and odorless, posing a potential leakage hazard. Tetrahydrothiophene is a universally compliant odorant used by gas companies nationwide. The product is stable, does not degrade over long distances, has a highly recognizable warning odor, requires only a small injection volume, does not corrode pipeline equipment, and burns without leaving any residue or blockage. It is suitable for various gas transmission scenarios, building a strong safety warning and defense line for residential and industrial gas use.
Ethyl mercaptan, as a general-purpose gas odorant, has high olfactory sensitivity, can quickly identify trace leaks, has stable chemical properties, distributes odor evenly in the pipeline network, and is economical in overall cost. It is suitable for long-term stable addition to urban natural gas pipeline networks and liquefied gas stations, meets local gas safety regulations, and strengthens the bottom line of gas operation safety.
