It was started in the United States in 1937 after a school explosion in New London, Texas caused by a natural gas/air mixture due. Texas started adding odor to natural gas, and it eventually was done across the world.
Pure natural gas is colourless and odourless. This means if there is a leak people will not be able to detect it until it builds up enough to become explosive. For this reason a chemical called Mercaptan is added to the gas to make is smell. Mercaptan is harmless, non-toxic and has a strong "rotten egg" smell.
what is the odor of urea and soda lime when mixed by nitrogen?
Natural gas has no color and it also has no odour. The odour that you can smell that is associated with gas, is man-made so that humans know that there is a gas leak. Otherwise, it would simply kill you :)
Actually no. Natural gas does not have a smell at all. A smell is added to it when its used for stoves and such.True Natural Gas does not have an odor, before or after combustion. The most common type of natural gas used is propane, in which they mix an additive to give it its tale-tell odor.yesPure natural gas (methane, CH4) is completely odorless. However, for domestic use, odorants are often added so that it is easier to detect a gas leak in your house. I'm not sure if the natural gas that comes out of the ground is pure or not, however, and there may be traces of other gases that do have a smell. The natural gas itself does not. However sour gas contains hydogen sulfide known as H2s and smells like rotten eggs. It is heavier than air and collects is low areas, which you smell when going through an oil field. A heavy dose can be deadly.
Carbon dioxide is added to the atmosphere;here when coal oil and natural gas are burned?
No! The rotten egg odor you smell is probably sulfur gas.
A leak of piped natural gas will smell something like rotten eggs because a mercaptan (a sulfur containing compound with a distinctive penetrating odor) is added to the gas before distribution. Natural gas as removed directly from the ground has no odor.
So the consumer can see if there is a gas leak. Gas normally has no odor and it thus undetectable.
No. But some gasses have odors. Natural gas doesn't have an odor but sulfur is added so it can be smelled. Otherwise a leak could go undetected and cause the death of someone living in a house.
Smell is added to natural Gas because it is odourless, tasteless and invisible. Mercapton is added to natural gas so the user is aware when it is present. ie when you have a gas leak.
odor
The mercaptan odor has been added specifically to assist in the detection of leaks. If odor from the gas is noticed, the implication is that you have a leak. Attend to it promptly.
Methyl mercaptan.Related Information:This strong smelling additive to natural gas is used to warn us of leaks. Natural gas has no smell, taste, or feel to it. So a chemical, that is naturally detectable, is added. It has an offensive odor, something like rotten eggs: very difficult to ignore.

No. natural propane is an odorless gas.
Mercaptane is added to natural gas; this has a strong smell and an escape of methane can be easily identified.
