According to the Gas Processors Association HD5 specification for LPG as a transportation fuel, LPG must consist of 90% propane, no more than 5% propylene, and 5% other which is primarily butane and butylene. It is produced as a by-product of natural gas processing and petroleum refining. The components of LPG are gases at normal temperatures and pressures.
How is Propane Made?
Propane is a by-product from two sources: natural gas processing and crude oil refining. Most of the LPG used in the United States is produced domestically. When natural gas is produced, it contains methane and other light hydrocarbons that are separated in a gas processing plant. Because propane boils at -44°F and ethane boils at -127°F, it is separated from methane by combining increasing pressure and decreasing temperature.
The natural gas liquid components recovered during processing include ethane, propane, and butane, as well as heavier hydrocarbons.
Propane and butane, along with other gases, are also produced during crude refining as by-products of the processes that rearrange or break down molecular structure to obtain more desirable petroleum compounds.
What are the Benefits of Using Propane?
Propane vehicles can produce fewer ozone-forming emissions than vehicles powered by reformulated gasoline. In addition, tests on light-duty, bi-fuel vehicles have demonstrated a 98% reduction in the emissions of toxics, including benzene, 1,3 butadiene, formaldehyde, and acetaldehyde, when the vehicles were running on propane rather than gasoline.
The cost of a gasoline-gallon equivalent of propane is generally less than that of gasoline, so driving a propane vehicle can save money. In addition, propane is the most accessible of all alternative fuels. In the United States approximately 3,000 publicly accessible facilities offer propane.
Approximately 85% of all propane used in this country comes from domestic sources, so driving a propane vehicle can help reduce U.S. dependence on imported oil and strengthen national energy security.

Current Virginia Clean Cities Propane Projects & Events
Gloucester County invites you to a Propane School Bus Dedication Ceremony to recognize Gloucester County Public Schools’ as the first propane school bus fleet in Virginia!
On October 26, 2010, Gloucester County Public Schools was presented a check from MARAMA and the keys to their 5 new propane school buses. Elected representatives spoke about the commitment by Gloucester County to environmental sustainability and energy security at Page Middle School.
Funding for the propane school bus pilot is being provided by the American Recovery and Reinvestment Act of 2009 via the EPA National Clean Diesel Program and the Virginia Department of Environmental Quality.
