Propane,
a by-product of natural gas processing and petroleum refining,
is a clean-burning energy source recognized for its transportability
and ease of use relative to alternative forms of stand-alone
energy sources. Propane is extracted from natural gas or oil
well head gas at processing
plants or separated from crude oil during the refining process.
It is normally transported and stored in a liquid state under
moderate pressure or refrigeration for ease of handling in shipping
and distribution.
When the
pressure is released or the temperature is increased, it is
usable as a flammable gas. Since propane is colorless and
odorless, an odorant is added to allow its detection. Like
natural gas, propane is a clean burning fuel and is considered
an environmentally preferred energy source.
Based
upon information provided by the Energy Information Agency,
propane accounts for approximately three to four percent of
household energy consumption in the United States. Propane
competes primarily with natural gas, electricity and fuel
oil as an energy source. This competition is principally based
on price, availability and portability.
