"Implementatifactor to such use is the supply of LPG." What?! -- ozzmosis 17:39, 8 March 2006 (UTC)
LPG can stand for
Laboratoire de Planetologie, Grenoble, France
but not for Liquefied petroleum gas. You can`t liquefied a liquid. Gasoline or petrol is a petroleum-derived liquid mixture, primarily used as fuel in internal combustion engines.
Petrolem is manufactured during the refining of crude oil, or extracted from oil, and comes in a liquid form. When we mix petro and ethanol,benzene,toluene,iso-octane and lead, to increase its octane rating then we have gasoline.
Most current or former Commonwealth countries use the term "petrol", abbreviated from petroleum spirit. In North America, the word "gasoline" is the common term, where it is often shortened in colloquial usage to simply "gas". It is not a genuinely gaseous fuel (unlike, for example, liquefied propane gas, which is stored under pressure as a liquid, but returned to a gaseous state before combustion).
propane is a three-carbon alkane, normally a gas, but compressible to a transportable liquid. It is derived from other petroleum products(Methane) during oil or natural gas processing. It is commonly used as a fuel for engines, barbecues, portable stoves and residential central heating. so the real LPG,LP Compressed natural gas (CNG) —Preceding unsigned comment added by 80.187.96.53 ( talk) 06:37, 17 March 2009 (UTC)
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)
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)
The article used to include a section on the use of LPG as a refrigerant. That said:
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.
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)
Many of the links in the refrigeration section do not lead to the point where they were originally. The links aren't broken, but they don't work properly. This section needs to be updated. JSR 18:03, 20 May 2012 (UTC) — Preceding unsigned comment added by JohnSRoberts99 ( talk • contribs)
WHY? YOU USES LPG AT HOME —Preceding unsigned comment added by 122.163.69.205 ( talk) 03:48, 21 May 2008 (UTC)
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)
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)

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. —Preceding unsigned comment added by 70.152.38.111 ( talk) 16:32, 22 September 2008 (UTC)
"LPG is the lowest carbon emitting hydrocarbon fuel available in rural areas, emitting 19 per cent less CO2 per kWh than oil, 30 per cent less than coal and more than 50 per cent less than electricity." Does that take into account the carbon emitted by the transport of the gas, and of the empty bottles? I suspect not, and that would rapidly eat up the carbon savings. —Preceding unsigned comment added by 128.232.228.174 ( talk) 20:38, 22 September 2008 (UTC)
The section about LPG and renewables is over-long, apparently designed to make this fossil fuel appear greener than it is. Any fuel can be used as an alternative to renewables. A simple statement that LPG can be so used and can be available where mains electricity and gas are not is sufficient, IMHO. Any more is NOT A NEUTRAL POINT OF VIEW unless there are strong specific references to back up any claim. 91.84.111.246 ( talk) 13:26, 23 December 2008 (UTC)
Question - when carried in the gas cylinder ,is LPG in liquid form? —Preceding unsigned comment added by 59.181.112.184 ( talk) 10:27, 2 February 2009 (UTC)
In the third paragraph (Vapor Pressure and such), I feel that the mention of the effect of chemical composition is important, but slightly irrelevant, as this article is only about propane. Now, if the article were talking about the difference in vapor pressure due to impurities, I feel that would be interesting to note. For example, some data (or charts) could be provided for vapor depressions due to the mixing of propane with other common refinery materials, such as hydrogen sulfide, carbon dioxide or various amines.

Most of the section applies mainly to the canisters themselves, not the gas as such. Surely it shouldn't be on this page 81.156.175.217 ( talk) 18:43, 19 March 2009 (UTC)
There's a statement in this article that LPG has been used in diesels, and the statement is followed by a citation-needed tag. As best I can tell, you can't run a diesel solely on LPG (at least, not without effectively converting the engine to spark ignition), but there are quite a few people who describe running an engine simultaneously on diesel and LPG, and the possible benefits thereof:

-- Khrulghan ( talk) 13:20, 12 August 2009 (UTC)
I was searching for information on LPG use in power stations, and came across the CO2 emmisions data in the opening paragraphs of this article. Unfortunately there is no source referenced so I can't use it. I added a citation needed tag, but then I realized that there are a lot of statements in those first paragraphs that don't have sources. Is it because they are the sort of facts that can be found in a text book and so considered 'common knowledge'? I thought I would ask here before putting in a half a dozen 'citation needed' tags. Thanks! WindyHaven ( talk) 22:55, 23 August 2009 (UTC)
This paragraph:
"If a container bursts, the LPG first spreads out as a supercooled liquid. This freezes anything within range. Then it boils into the atmosphere and become an oxygen-displacing gas, which asphyxiates any creatures in the affected radius. This gas spreads out to cover several hundred times more area than the liquid from which it comes. A single tank of LPG can cause oxygen displacement of many square miles. At some point this gas is diluted by the atmosphere. It will then reach a point of an ignitable mixture. When this happens, a fireball of many square miles will consume everything in the area."
paints a grim (and, seemingly, somewhat exaggerated) picture of what might happen if an LPG container should rupture. Absent any references for those claims, I suggest that this paragraph should be removed. —Preceding unsigned comment added by 88.109.165.150 ( talk) 22:40, 31 October 2009 (UTC)
The EAST OHIO GAS CO. EXPLOSION AND FIRE took place on Friday, 20 Oct. 1944, when a tank containing liquid natural gas equivalent to 90 million cubic feet exploded, setting off the most disastrous fire in Cleveland's history. Homes and businesses were engulfed by a tidal wave of fire in more than 1 sq. mi. of Cleveland's east side, bounded by St. Clair Ave. NE, E. 55th St., E. 67th St., and the MEMORIAL SHOREWAY. At approx. 2:30 P.M., white vapor began leaking out of Storage Tank No. 4, which had been built by the East Ohio Gas Co. in 1942 to provide additional reserve gas for local war industries. The gas in the tank, located at the northern end of E. 61st St., became combustible when mixed with air and exploded at 2:40 P.M., followed by the explosion of a second tank about 20 minutes later. The fire spread through 20 blocks, engulfing rows of houses while missing others. The vaporizing gas also flowed along the curbs and gutters and into catch basins, through which it entered the underground sewers, exploding from time to time, ripping up pavement, damaging underground utility installations, and blowing out manhole covers. The immediate area surrounding the burning district was evacuated and refugees were sheltered in Willson Jr. High School on E. 55th St. where the Red Cross tried to care for approx. 680 homeless victims.

This section consists almost entirely of original research in the form of anecdotal detail, personal observation and prescription. The editor who originally added much of the questionable material has tried to justify this on my talk page by asking if I was personally experienced in the area: this is irrelevant. All material in articles should be adequately referenced to given secondary sources, preferably with inline citations, and our articles should neither devote undue coverage to certain sub-topics relative to the length of an article as a whole (as the safety section does here: it comprises almost 50% of the article length) nor contain material of a prescriptive nature. This is not a safety manual, nor an essay: it simply describes the subject. I believe that much of the prescriptive or anecdotal material in that section is unnecessary to understand the subject, and as such I'm going to try to remove it in the near future.

LPG is stored in cylinders or spheres, not tanks. Although the colloquial English word "tank" is frequently used, it is technically incorrect. A tank is an ambient-pressure storage vessel, with or without a roof, such as a "water tank" used as a reservoir for city water or a tank used for storage of crude oil. Due to the pressure vessel nature of LPG containers, they are always of circular cross-section. A "tank" can have an arbitrary cross-section. The word "tank" will be summarily removed from this article and anyone who uses it here will be banished to elementary school.— Quicksilver T @ 17:50, 22 April 2010 (UTC)
I looked through all the links, and selected a few of the more important and useful looking ones. May well not need any at all. —Preceding unsigned comment added by Scientific29 ( talk • contribs) 16:09, 30 August 2010 (UTC)
Firstly there is no "isopropane" so I have removed the "iso." (Three carbons - as propane has - cannot be arranged in a "T" such as butane, C4H10 can. Hexane is the first in the series with more than one iso- formula - pentane, like butane, is either linear or has one alternative structure) One can only surmise this nonsense originated with some chemistry-deficient PR flack somewhere and has been incorporated into this article (and the one on propane, and who knows how many other articles on propane as a refrigerant.) "Isopropane" is a trade term (unfortunate) for a refrigerant containing small amounts of isobutane.
I came here today looking for information related to natural gas engines. There is a dearth of clear information on the internet. It appears proposals for natural gas engines refer to propane or propane/butane mixtures. This is relevant because methane is the least CO2-generating fuel per unit energy, propane significantly more so.
"Liquified petroleum gas" is a poor term. We are apparently stuck with it. Wikipedia can be more analytical than trade expressions, however.
Molecular diagrams would vastly increase the informative content of this article! I'm not savvy on these Wikipedia matters, however. Help from an experienced editor would be good! Mydogtrouble ( talk) 14:02, 24 February 2012 (UTC)
For the remark that LPG has a lower energy density per volume than gasoline (petrol) or fuel oil, where someone put a "cite" tag in, all that needs to be done is to specify the actual figures for gasoline or fuel oil. I don't believe this would be a violation of "no original research" because these are measurable physical quantities and thus held to be common fact. -- 208.181.64.45 ( talk) 03:48, 29 May 2012 (UTC)
This Fire Risk and Mitigation section has been in this topic and contested for a long time and we need to finally deal with the issue. I would suggest moving the topic to the fireproofing section, where it fits a little closer. The LPG article is focused mainly on fuel issues and does not discuss manufacture, storage or transportation in any significant detail. This section then becomes a bit confusing as we have a discussion regarding 30,000 gallon vessels in a topic primarily focused on 5-500 gallon vessels. JSR ( talk) 16:35, 19 June 2012 (UTC)
This is what's wrong with WP. This an unsourced, wordy, pontificating, POV, soapbox essay by a sole single issue editor - and you're debating if this should not be removed until it can be improved. Jeez. — Preceding unsigned comment added by 159.221.32.10 ( talk) 04:43, 8 July 2012 (UTC)
The article had a part where it stated LPG isn't toxic so there's no chance of poisoning. A brief glance at our articles (or any MDSS) on LPG's component gases will tell you how silly that particular statement was. I've removed it. Peter Greenwell ( talk) 13:10, 8 September 2012 (UTC)
LPG is not considered to be toxic. Toxic compounds take an "active biological" role in causing "bad effects," such as cyanide interfering with the cell's ability to use oxygen ( see "Cyanide poisoning".) The primary cause of harm of compounds such as nitrogen, argon, LPG, etc. is the displacement of oxygen causing asphyxiation. OneNemesis ( talk) 14:57, 21 February 2013 (UTC)
Important is a very over used "opinion" word. Given the usage, one could say "important" about methane, carbon monoxide, nitrous oxide, etc. as all of these are greenhouse gases (see "IPCC list of greenhouse gases". Conspicuously absent, however, is the largest component, water vapor, which comprises ~95% of the greenhouse gases. OneNemesis ( talk) 15:14, 21 February 2013 (UTC)
Removed this - appears to be WP:OR, or at the very least unsourced:
For mobile tanks (propane, LNG, oxygen) You might want to consider this: Have 2 tanks with one inside the other the inside one contains the product, it will have 4, 6, 8, 10, 12 rows of unsightly and non aerodynamic Pressure Relief Valves (PRV's) attached to the outside depending on the diameter of the tank this way if the tank rolls off the truck or truck rolls over there will be valves in a position to vent the gas. Make sure that BOTH ends have valves to in case the tank winds up on end.
EACH row of PRVs will have 3 or more valves set to go at different pressures in case a fire heats the product so much that even with the valve open the pressure could still cause an explosion. Since when a higher pressure valve opens a lower pressure one MIGHT close in order to vent more gas _ THE DIAMETER OF EACH VALVE MUST BE LARGER THAN THE VALVE BEFORE.
The will be pipes going from the PRV 's to the good looking and aerodynamic outside shell. The ends will be shaped to be flush with the shell. [1]
- ^ TO ME this is common sense. YES, there will be more tankers on the road __BUT __ they will be a lot safer.
- added by @ SB3972:. Note that I'm not disagreeing with anything, just saying that it doesn't meet Wikipedia's policy against original research, WP:OR. I left in the paragraph on BLEVEs and release valves by the same contributor, as I thought it made sense, though it's also unsourced. -- Chriswaterguy talk 05:23, 15 November 2013 (UTC)

Feb 4 (Reuters) - An Indian government panel on Wednesday
suggested ending controls on retail prices of petrol and diesel. It has also suggested raising prices of kerosene sold through the country's public distribution system and the 14.2-kg liquefied petroleum gas (LPG) cylinder.
Here are revisions since 1989 in the retail prices of four
sensitive petroleum products in Delhi. Petrol, diesel and kerosene prices are in rupees per litre, while LPG prices are per cylinder.

"LPG is liquefied by slight pressurization, not by cooling." "The pressure at which LPG becomes liquid, called its vapour pressure, likewise varies depending on composition and temperature; for example, it is approximately 220 kilopascals (32 psi) for pure butane at 20 °C (68 °F), and approximately 2,200 kilopascals (320 psi) for pure propane at 55 °C (131 °F)." => LPG pressure = 220 kilopascals (32 psi) = 2.2 Bar, that's indeed not a lot. Can I add that it is 2.2 Bar? I think more people will understand that, don't you agree? Cheers, SvenAERTS ( talk) 13:49, 28 October 2020 (UTC)
