Introduction |
Demand for clean-burning natural gas (composed primarily of methane) is growing around the world. In North America, a dynamic gas-energy marketplace offers an array of competitive choices - and risks - from wellhead to burner tip. Many gas utilities and consumers gain enhanced security and flexibility - while reducing the overall cost of energy supply - using propane peak shaving and standby systems. Most of these systems produce "propane-air" for direct replacement of natural gas during peak demand periods.

| LPG or LP-gas refers to several gas liquids, including propane and butane. |
| NG |
Natural Gas
|
| NG is a mixture of methane and various other hydrocarbons an inert gases. |
| NGLs |
Natural Gas
Liquids
|
| NGLs are hydrocarbon components of natural gas other than methane, including ethane, propane and butane. |
| Propane is derived during both natural gas production and crude oil refining. Common trade names include LPG, LP-gas and HD-5 Propane. |

What's
SNG? |
SNG can mean several forms of 'alternate' natural gas. Synthetic Natural Gas commonly refers to the output of 'coal gasification' plants – but may also be used to indicate a mixture of propane or other LPGs and air. Substitute Natural Gas and Supplemental Natural Gas almost always refer to 'LPG-air' mixtures – and 'propane-air' is the most common form.
