Cultural References
I found that this is a great article, and this might sound a bit silly, but I think that we should mention King of the Hill under a cultural reference. However that's just my opinion. Who else agrees? Other than that, I think it's a very informative article that explains propane in a language that we can all understand. Thanks guys :) Leo16mmiv (talk) 17:17, 6 October 2008 (UTC)
Vandalism
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.

Liquid density
http://encyclopedia.airliquide.com/Encyclopedia.asp?LanguageID=11&CountryID=19&Formula=&GasID=53&UNNumber=&EquivGasID=41&VolLiquideBox=&MasseLiquideBox=&VolGasBox=&MasseGasBox=&btnMSDS=0&MSDSLanguageBox=0&RD20=29&RD9=8&RD6=64&RD4=2&RD3=22&RD8=27&RD2=20&RD18=41&RD7=18&RD13=71&RD16=35&RD12=31&RD19=34&RD24=62&RD25=77&RD26=78&RD28=81&RD29=82 states that liquid density at 1 atm and boiling point is 0.58, this article says 0.50. Is this a discrepancy or different pressure/temp?
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)
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).
I don't see anything about the Combustion Temperature, to compare it with MAPP gas. —Preceding unsigned comment added by 70.136.198.121 (talk • contribs) 17:15, 3 February 2006
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)
Refrigerant
i cant see how the LPG can take as a refrigerant and what is the procedure for it —Preceding unsigned comment added by 203.88.140.107 (talk • contribs) 11:30, 20 February 2007
- Propane, butane and other similar hydrocarbons have similar characteristics to R12, in that they will condense and evaporate under similar pressure and temperature conditions and absorb and emit heat in similar quantities in the process. Hence, nominally pure propane will operate at a higher head pressure (compressor output pressure) than R12 and get colder evaporator temperatures, while a 60/40 propane/butane blend will behave virtually identically to R12. --Athol Mullen 04:00, 31 July 2007 (UTC)
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.
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)
Name Derivation?
Its name was derived from propionic acid.
I think that name is from normal naming convention. Prop means three carbons and -ane means only single bonds. 195.163.176.146 05:21, 15 May 2007 (UTC)
Regardless of this the statement does not belong in the properties and reactions section; I've moved it to the history section, with the addition of the word originally. Even here I'm not sure if it is a bit misleading, so would welcome another opinion.PiFanatic (talk) 00:00, 24 January 2009 (UTC)
Phase diagram?
It would be nice to have a phase diagram, since propane is so often stored pressurized as a liquid. —Ben FrantzDale 19:29, 25 June 2007 (UTC)
Use in explosive devices?
Following the recent attempted bombings in the UK, where Propane tanks appear to have been a key ingredient; I was wondering if this article should discuss the (mis)use of propane as an explosive agent, as opposed to a fuel.
It certainly has been used in attacks, and some accounts exist of it being successfully used to create deadly explosions (http://www.emergency.com/frncboms.htm). But I have witnessed a propane tank rupturing when a catering van caught fire at an event. There was a fireball and the burning tank broke free of the area with considerable force and injured people in the crowd. But as I would expect there was no explosion, due to a lack of internal oxidiser..
Would a terrorist (or other criminal) use propane tanks for secondary effects (incendiary effect and sensation), rather than as a primary explosive. Or is it practical that it could make an effective thermobaric (fuel-air) device, this has been hinted at by media 'experts' discussing the London attacks. -- EasyTarget 15:20, 5 July 2007 (UTC)
The amount of required heat and direct flame impingement sustained over a long enough period of time would allow a propane tank to become an explosive device. In short, propane tanks are poor tools for even a secondary explosive device. Propane tanks will rupture (or create an explosion if ignition is present) following either 1) internal pressure exceeds that of the discharge rate of the safety relief valve or 2) structural integrity of the vessel is compromised (usually by flame) to such an extent the welds give way. I'm of the opinion that propane tank explosions are far too uncommon to warrant recognition in this article. Propane tanks do not explode or rupture as easily as the public believes. Perhaps this explosive topic would be better suited for the BLEVE article. Mtt124 03:41, 5 September 2007 (UTC)
Bottle size
The article text refers to "ubiquitous 5-gallon bottles" but I think this may be Euro-centric. In the US and Canada, 20 pound bottles (which may net to near 5 gallons - but they're never referred to as that here) are universal for use in/on recreational vehicles, barbeques, and large campstoves. Smaller (1-pound?) cylinders are typically sold in grocery and sporting goods stores for $3-5 and are the universal standard for small (tabletop) barbeques, camp lanterns, and hand-held welding/soldering torches.
Someone with experience on both sides of the Atlantic (or Pacific) would be ideal to sort this out.
BTW, in 2007, 20# cylinders are running about $USD 20, +/- $5, to refill - might be nice to add this information to the article.
Finally, I've removed the reference to the term "tarnatches" as a name for propane bottles. I think this is a joke, or at the very least an extremely local naming reference. A Google search for the term turns up *no* other references to that word, other than this Wikipedia article and its clones. —Preceding unsigned comment added by 209.63.111.55 (talk • contribs) 23:16, 30 July 2007
External Links
I have created a website that is currently being used by several companies (for safety training) and state associations that explains propane in non-technical, simple to understand terms. It is safety centered with a focus on explaining somewhat technical subjects in easy to understand language. I believe it would be an excellent resource for visitors that are searching for propane information and aren't familiar with it. The site is Propane 101. I thought it would be a good external link for the Propane page. Thoughts? Mtt124 22:48, 4 September 2007 (UTC)
I'd love to help Carlos, but what do you suggest that I cite? I'd like to talk about useful propane information.Mtt124 01:57, 7 September 2007 (UTC)
I added a link that points to descriptive propane properties data. The page is a breakdown of individual properties with a description of how each characteristic affects the use and understanding of propane. Mtt124 15:38, 3 November 2007 (UTC)
Potato Guns
I'm not sure that the propane article is much of a place for references to potato guns. I'd recommend deleting all hyperlinks to the potato gun article. Propane is recognized worldwide as an energy source for homes, industry, and vehicle use. Let's not dilute the focus of this article with the mention of potato guns. Staying focused on primary uses would be much more beneficial to readers. A potato gun editor also has placed an online Potato
