Implementatifactor

"Implementatifactor to such use is the supply of LPG." What?! --ozzmosis 17:39, 8 March 2006 (UTC)[reply]

LPG in Cooking Sprays

Anyone can advise me on the safety in using the cooking sprays which as I understood the propellant is LPG...

RESPONSE

WANK - Worldwide Analysis Non-Industial Knowledge is an organisation notifying consumers about the majority of safety precautions and facts of using cooking equipment. If you download the PDF 'knowledge booklet' from their website you will find under the section 4.53.2 there is a specific section that explains in detail on sprays and propellants and how to spray without causing any harm.

Separation of Autogas section

I've created a new page at Autogas (replacing a redirect to here) and will shortly move the content of the Usage in cars section to that page. I will also be moving some of the references at the same time.

This may create the need for other cleaning up in this article. If you spot something, feel free to fix it. :) --Athol Mullen 06:32, 17 November 2006 (UTC)[reply]

Forklifts?

Some (small) warehouse forklift trucks have red gas bottles mounted on the back? Does anyone know about this? —Preceding unsigned comment added by 86.17.216.130 (talk) 10:04, August 24, 2007 (UTC)

A Yep some forklifts shore do run on LPG one from a joinery plant used to always come an fill up at the local gas station wen i was there, some use 9kg 4.5kg bottles were as this one i remember had a big 45kg bottle Maximum effect (talk) 21:28, 9 January 2008 (UTC)[reply]

Flash point?

The article used to include a section on the use of LPG as a refrigerant. That said:

in highly refined form it [propane] exhibits a relatively high flash point of 891 °C (1635 °F)

This means that below 891 °C, if you mix propane with air and try to ignite it with a match, then you will fail, no matter what the concentration. I don't believe this. Perhaps they didn't know the difference between the flash point and autoignition temperature?

I removed the whole section, since it was confusing, and I don't know enough about the subject to fix it. If someone does then it would be nice if they could replace it with correct information.

Refrigeration

This mentions that LPG is better than refrigerants such as 134a because it doesn't deplete ozone, but accourding to R134a, neither does 134a. RobertDahlstrom 10:23, 26 August 2007 (UTC)[reply]

Indeed, I've reviewed several references and the issue with HFC134a is greenhouse effect, not ozone depletion. Hence, I've removed reference to ozone depletion from the refrigerants section. --Athol Mullen 23:17, 26 August 2007 (UTC)[reply]

LPG

WHY? YOU USES LPG AT HOME —Preceding unsigned comment added by 122.163.69.205 (talk) 03:48, 21 May 2008 (UTC)[reply]

Reason for use in homes

LPG is sometimes used in homes that cannot be supplied by mains gas. This could be because they are too far away from any gas mains. For this purpose, the LPG can be stored in underground/above ground tanks. --N (talk) 10:09, 12 June 2008 (UTC)[reply]

It's not just because of remote locations. In some suburban areas in Australia, there are sections of suburbs with reticulated natural gas, and other sections of the same suburb just a few streets away that do not have reticulated gas. People in the latter locations who want to use gas have no option but to use bottled LPG. --Athol Mullen (talk) 11:07, 12 June 2008 (UTC)[reply]

how to better say this

Current article reads Air source heat pumps extract heat from the surrounding air to produce energy. Again, LPG can be used as a supplementary heat source. I think I can see what that is supposed to mean, but these heat pumps don't actually produce energy from the surrounding air. Needs restatement IMO. Andrewa (talk) 15:32, 9 August 2008 (UTC)[reply]

Heat pumps simply move heat from one place to another. If the heat is used to power a heat motor, it would be appropriate to say "concentrate energy" instead of produce energy. If the heat pump is simply used to heat something (air, water, whatever), then "concentrate heat" would be more appropriate. --Athol Mullen (talk) 04:18, 10 August 2008 (UTC)[reply]

Sort of. One problem is that energy has several possible meanings here of which the strict thermodynamic meaning is only one. In this sense, producing energy is a nonsense as energy is conserved. In the sense of energy resources it's also inaccurate. Hmmm... Andrewa (talk) 12:51, 10 August 2008 (UTC)[reply]

External Links

It looks as the external links section has a good bit of commercial promotion. Deleting the obvious and will leave the remainder to the powers that be. Mtt124 (talk) 00:52, 7 September 2008 (UTC)[reply]

If an internal page (from a commercial site) has relevant information directly related to LPG, an external link is appropriate. Otherwise, I believe, this page is ABOUT Liquefied Petroleum Gas, not about its distributors. Correct me if I'm wrong.Mtt124 (talk) 01:04, 7 September 2008 (UTC)[reply]

I agree with the cull that you've done. It was overdue. Any external links on any page should point to something directly relevant to the subject. For example, the web site of a company marketing LPG is not appropriate, but a sub-page with technical information might be. In that type of case, the sub-page, not the top page of that site should be linked. Before culling sites, I like to look through to see if there is a worthwhile sub-page to change the link to rather than removing it, but wikipedia is not a directory, either, so if multiple sites have similar information, we really don't need all of them! --Athol Mullen (talk) 08:07, 7 September 2008 (UTC)[reply]

Better

So which is better? LPG, CNG (compressed natural gas) or LNG (liquefied natural gas)? Up and over for a six! (talk) 06:28, 11 September 2008 (UTC)[reply]

Depends what your criteria are. If they are range and performance, LPG is better. If it is overall running cost for a vehicle that stays close enough to its base not to have problems accessing refuelling facilities and power output is not critical, it's CNG. The answers will also vary depending what country or part of a country it's in due to variations in pricing and availability of fuelling facilities. Obviously, it'd be nice to have this sort of stuff in one or more of the relevant articles but it'd need to be adequately referenced... --Athol Mullen (talk) 07:12, 11 September 2008 (UTC)[reply]

Safety

Why is the safety section so disproportionately long compared to the others. It makes it sound like you are going to die if you are anywhere near this stuff.
