What Is Propane?
Propane is a hydrocarbon (C3H8) and is sometimes referred to as liquefied petroleum gas, LP-Gas or LPG. Propane is produced from both natural gas processing and crude oil refining. It is nontoxic, colorless and virtually odorless. As with natural gas, an identifying odor is added so the gas can be readily detected.
Propane is an approved, clean fuel listed in the 1990 Clean Air Act as well as the National Energy Policy Act of 1992.
Propane is one of the lightest, simplest hydrocarbons in existence, and, as a result, is one of the cleanest burning of all fossil fuels. Burning coal to generate electricity releases carbon dioxide and other pollutants into the atmosphere.
Propane gas is nontoxic, so it’s not harmful to soil and water. Because propane does not endanger the environment, the placement of propane tanks either above or below ground is not regulated by the Environmental Protection Agency. According to the EPA, much of the sulfur dioxide in the atmosphere, which produces acid rain, is attributable to coal-fired electricity-generating facilities. In contrast, neither the process by which propane is produced nor the combustion of propane gas produces significant acid rain contaminants.
Propane Is a Good Value
Overall, propane fuel for fleet vehicles typically costs less than conventional or reformulated gasoline. Many states
Propane Is a Versatile Fuel
Propane is used by millions of people in many different settings – in the home, on the road, on the farm, and at work.
It is used in 48 million households as well as many businesses for water and space heating, indoor and outdoor cooking, clothes drying, and backup power.
Propane is commonly used to fuel buses, light- and medium-duty trucks, vans, shuttles, taxicabs, and police and government vehicles. Propane autogas is an approved clean alternative fuel under the Clean Air Act of 1990 and the third most popular vehicle fuel worldwide behind gasoline and diesel.
Nearly 900,000 farms in the United States use propane to run pumps and engines, heat buildings, and dry and process crops.
Propane is easy to transport and can be used in areas beyond the natural gas mains. Because it is 270 times more compact as a liquid than as a gas, it is economical to store and transport as a liquid.
Propane Is a Safe Fuel
The propane industry has developed numerous methods to ensure the safe transport and use of propane:
Propane equipment and appliances are manufactured to rigorous safety standards.
Propane has a narrow range of flammability when compared with other petroleum products. In order to ignite, the propane-air mix must contain from 2.2 to 9.6 percent propane vapor. If the mixture contains less than 2.2 percent gas, it is too lean to burn. If it contains more than 9.6 percent, it is too rich to burn.
Propane won’t ignite when combined with air unless the source of ignition reaches at least 940 degrees Fahrenheit. In contrast, gasoline will ignite when the source of ignition reaches only 430 to 500 degrees Fahrenheit.
Because it is released from a pressured container as a vapor, propane can’t be ingested like gasoline or alcohol fuels.
Because propane is virtually odorless and colorless in its natural state, a commercial odorant is added so propane can be detected if it leaks from its container.
