Density of liquid and gas ... The density of liquid and gaseous propane are given on the next image. Vapor pressure of liquid. P in mm Hg: 1: 10: 40: 100: 400: 760 ...
The density of propane gas at 25 °C (77 °F) is 1.808 kg/m 3, about 1.5× the density of air at the same temperature. 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 ...

LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3 ) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3 ), which means that LPG cannot simply be substituted for ...

The Wobbe index is expressed in MJ/Nm³ (where 'Nm³' indicates'm³ in Normal conditions), or sometimes in BTU/scf.In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 39 MJ/Nm³ (1,050 BTU/scf) and the specific gravity is approximately 0.59, giving a typical Wobbe index of 51 MJ/Nm³ (1,367 BTU/scf).
In contrast, wet natural gas also contains significant portions of other liquids such as ethane, propane or butane (also known as Natural Gas Liquids). Wet natural gas is used for petrochemicals as well as gasoline (petrol). In 2023, the United States has led the world in both natural gas production and natural gas exports.
[56] [57] Autogas use by car drivers can help the United States to reduce dependence on foreign oil as 90% of all U.S. Autogas is produced in the U.S. [58] [59] In 2005, a provision was enacted that placed a 50-cent per gallon tax credit on propane autogas as part of H.R. 4853, making it $1 per gallon cheaper than petrol on average.
