The National Propane Gas Association has a generic MSDS available online here. (Issued 1996) MSDS from Suburban Propane, L.P dated 5/2013 in the SDSdata.org database
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 composition of the supplied gas has varied widely, with the gases as supplied by different repackagers/resellers at any one time varying, as well as the general composition varying over time, but a typical composition for an early Dow gas might be: methylacetylene (propyne) 48%, propadiene 23%, propane 27%. For a later Dow/Petromont gas ...
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).
Standard Dry Air is the agreed-upon gas composition for air from which all water vapour has been removed. There are various standards bodies which publish documents that define a dry air gas composition. Each standard provides a list of constituent concentrations, a gas density at standard conditions and a molar mass.
AmeriGas was founded in 1959. In October 2008, it acquired the propane assets of Penn Fuel Propane for $32 million. [4]In January 2012, it acquired Heritage Propane from Energy Transfer Partners for approximately $1.46 billion in cash and $1.32 billion in common units and the assumption of debt.
Density * (g/L) ODP GWP Electron-attaching Properties Sulfur hexafluoride: SF 6: 3.0: 146.06: 6.164 22800 The most popular insulating gas. It is dense and rich in fluorine, which is a good discharge quencher. Good cooling properties. Excellent arc quenching. Corrosive decomposition products. Although most of the decomposition products tend to ...
