Odorants will condense in the cold box, and if there is a large amount of them, it may cause blockages in pipelines, valves, etc. If the amount is small, just a trace amount, it won’t cause any major consequences. Current odorants generally use **thiophene**, which is stable in nature; however, the conditions required for producing thiophene through hydrogenation are quite stringent, resulting in high production costs at present. Physical appearance and properties of the data: colorless liquid. Melting point (°C): -96.2 Boiling point (°C): 119 Relative density (water=1): 1.00 Flash point (°C): 12.8 Solubility: Insoluble in water; soluble in ethanol, ether, benzene, and propylene. **Thiophene is a colorless, transparent, volatile liquid that is insoluble in water but miscible with ethanol, ether, benzene, and propylene. It has a strong, unpleasant odor; the stench it produces is stable and does not dissipate easily, and it can be detected at a concentration of 0.01 PPm in the air.

It’s added with domestic gas, but now since it’s transported through pipelines, it’s likely that it’s also added in some aspects of pipeline network management. As for the place the original poster is referring to, I think it’s the stage of high-pressure transmission or the stage of compression and liquefaction; I’m not sure why it’s added

Is this deodorant harmful to the body? After all, we use natural gas at home!

Odorants are added to prevent greater harm – leaks that could lead to more serious accidents. Of course, if you are highly sensitive to the toxicity of the odorants in natural gas and strongly refuse to use it, you can switch to electric cooking appliances or coal for cooking. However, using electricity, just like using coal, has its own harmful aspects, such as electric shock and carbon monoxide poisoning. Chlorine is also added to our drinking water, and it is harmful to humans as well ； There are also gases in the air we breathe ； Sunlight contains harmful ultraviolet rays ； …… You live too meticulously; it must be so exhausting.

When unloading the liquid in the tank trucks, odorizers were mixed in; when these trucks are loaded, the odorizers end up in the processing equipment.
