This Post: LP-GAS ODORIZATION INFORMATION FOR PROPANE (C3H8) TRADE NAME:LIQUIFIED PETROLEUM GAS, LP GAS, LPG, HD5, PROPANE.
Maybe this will answer your question about the smell in propane. Listed below is a web site that goes into detail about the safety of propane and the odor smell of "ROTTEN EGGS" of "ETHYL MERCAPTAN" that is added for
YOUR safety in using propane and listed like gasses.

The web site above explains about the smell of propane in NEW and OLD tanks.
No. Actually neither of these links address the essential
issue of stratification - MORE smell when the tank is
near empty or of the smell surviving combustion and
NOT triggering a propane detector.
The issue the OP brought up was "bad smell" when
pilot light was burning and you said that was caused
by the tank being near empty. Neither of your links
address that issue. The first is a very detailed
explaination of how and why "smell gas" is added -
something most of us have known for ages. The
second discuses the reasons for the FADING - not
INCREASING - of the smell in certain cases. Again,
no mention of stratification or smell surviving
combustion and NOT triggering a propane
Please think about this for a moment: if the smell
chemical stratifies - congregates at the bottom of
your tank - it will certainly do the same in any
tank. Including the tank at the propane refill
station. That means that if you get your tank
refilled when their tank is almost empty, you
will get a huge dose of the smell gas and would
smell it from the git-go, rather than just when
your tank is almost empty. The opposite if you get
the refill when their tank was just topped off - ie
little smell. THIS JUST DOESN'T HAPPEN.
It doesn't pass the "Smell Test"! [Excuse the bad
Add to that the question about lack of regulatory
prevention of a situation that would cause false
positives, with *bad* results and your claim just
doesn't make sense. Again I ask if you have links
to scientific literature that addresses the dual issues
of "Smell surviving combustion" and "Smell
congregating at the bottom of the tank".
Ready to be proven wrong.....by REAL DATA.....
In the absence of such, we must rely on what we
have always experienced - the smell is detectable
only in the presence of unburned propane gas.
And when we smell it, there is NO question of a
