Smell of Propane

A Word on the Smell of Propane

You probably already know that propane is odorless. Which means it has no odor, and you can’t smell it.

Why, then, does everyone keep talking about that rotten egg smell associated with a propane gas leak?

It’s called mercaptan, and it’s a naturally occurring chemical found in foods- like hazelnuts and cheeses, and in nature- like in swamps and some fossil fuels. Ethyl mercaptan is added during the processing and refining process, which makes leaks detectable.

But just because the odor was added doesn’t mean it’ll always stick around. Under certain conditions the odor might oxidize and lose its intensity. This is called odor fade.
