Hi guys, I reverted the edit by 66.57.32.80, that added the phrase "Do not use Wikipedia as your only resource, anyone can edit it. It is a good place to start research, but always clarify it with more reliable sites." While the warning may be true, it doesn't belong tacked in the middle of the page.

[edit] Odor

I've heard (ok, it was from Hank Hill) that Propane has no natural odor, but that odor is added to make it detectable (for safety reasons). Is this true? If so, what is added? --Spikey 23:04, 22 Mar 2004 (UTC)

I've heard several times that this is true.....always wondered what it was also. Jwrosenzweig 23:05, 22 Mar 2004 (UTC)

I believe is naturally odourless, and what's added is ethyl mercaptan. The same goes with methane - at least that is what I was taught at school. If I can find something to collaborate, I'll add it to the articles in question. -- DrBob 23:27, 22 Mar 2004 (UTC)

Thank you Dr. Bob! Another bizarre mystery solved. :-) I appreciate your willingness to instruct the less scientifically apt among us (I refer to me -- Spikey can make his own declaration regarding his scientific experience :-). Jwrosenzweig 23:31, 22 Mar 2004 (UTC)

Mercaptin is added when a transport loads from the pipeline or distribution point. Amazingly, only a small amount is needed to properly odorize a 9600 gallon tanker, about 1 quart. It is required to odorize at this point as it is required by law before transporting over the road (DOT REG).

The substance used varies from country to country—in the UK we use t-butyl mercaptan, for example—but the principle is the same, you have to add something so that you can smell it if it leaks! Physchim62 (talk·RfA) 13:09, 2 November 2005 (UTC)

I'm getting my doctorate in Pharmacology and I have dealt with the bitter scourge known as the the Mercaptin, I can confirm that it is added as an aromatic agent, its the Pepe` Le Pu of the chemical and pharmaceutical world. Oh and it tastes awful. Etherealmuse 17:15, 22 January 2006 (UTC)

I don't see anything about the Combustion Temperature, to compare it with MAPP gas.

It might be an idea to add some info about safety with Propane, IE the LNG article. I have heard about there being a roper term for a damaged (ruptured)propane tank and apparently needs to have a certain mixture of air and propane and that it is difficult to ignite, however, I'm not sure that is true.. Anyone have any info about this? Magu 01:39, 14 July 2006 (UTC)

Paragraph on "Fuels". Where did the last sentence come from? Quote" Additionally, most of the entire North American chemical industry uses propane to power their huge facilities that crack or distill industrial chemical products. 'unquote. I have spent over 30 years in the USA chemical industry. Rarely, if ever, have I seen Propane used as fuel for such. Maybe for small, remote locations, but not along the Gulf Coast nor NorthEast, where most chemicals are produced. So let's think about that sentence and see if it should be deleted.--Chris 10:33, 6 December 2006 (UTC)

i cant see how the LPG can take as a refrigerant and what is the procedure for it

[edit] 6.5 BILLION?

Might want to check the number of households - didn't planet Earth just recently go over 6 billion people? I don't think there's 6.5 billion households in USA and Mexico. —The preceding unsigned comment was added by 12.208.189.150 (talk) 21:26, 2 March 2007 (UTC).

[edit] Dodgy Numbers

The statement under Uses that "6.5 billion American and mexican (sic) households use propane as their primary heating fuel" cannot possibly be right, can it? Unless someone has a sensible number available, I suggest this should be completely removed. CarbonUnit2 08:53, 3 March 2007 (UTC)
