The density of liquid propane at 25 °C (77 °F) is 0.493 g/cm 3, which is equivalent to 4.11 pounds per U.S. liquid gallon or 493 g/L. Propane expands at 1.5% per 10 °F. Thus, liquid propane has a density of approximately 4.2 pounds per gallon (504 g/L) at 60 °F (15.6 °C). [30]

Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, n-butane and isobutane. It can sometimes contain some propylene , butylene , and isobutene .

The cost to convert a vehicle to propane in Canada is approximately CA$4,000 to CA$6,000 for the current vapour or liquid fuel injected technology, and fleet users can expect a payback on the conversion cost within a year. Converting a vehicle to propane is approximately half the cost of converting a vehicle to natural gas in Canada.
Several types of valve connections for propane, butane, and LPG containers exist for transport and storage, sometimes with overlapping usage and applications, and there are major differences in usage between different countries. Even within a single country more than one type can be in use for a specific application.
In order to help pay for the costs stemming from the Deepwater Horizon explosion, BP plans to sell its stakes in gas and oil properties in Vietnam. It maintains joint ownership of such projects — Lan Tay-Lan Do gas field and Nam Con Son pipeline — with ONGC, PetroVietnam, and ConocoPhillips.
Propane has a low-carbon content, has no methane emissions, is nontoxic, and is designated an approved clean, alternative fuel under the Clean Air Act Amendments. History Established in 1931 as the National Bottled Gas Association (NBGA), in 1937 the name changed to the Liquified Petroleum Gas Association (LPGA) to encompass the entire LP-gas ...
