Propane is liquefied petroleum gas that is derived
from both oil and natural gas refineries. Propane naturally
occurs as a gas but can be converted to its liquid form under
When liquefied, propane can be compressed down to approximately
250 times its volume. Hence its stored, marketed and transported
in its liquid form. When unpressurised (e.g. when the propane
tank valve is opened), it returns to its gas form and can then be used.
The chemical formula for propane is C3H8 - 3 Carbon molecules
and 8 Hydrogen molecules. It has a boiling point of -44 degrees
Fahrenheit and 1 gallon of liquid propane weighs roughly 4.2 lbs.
Propane has a flash point of -156 degrees Fahrenheit and produces
roughly 91,547 BTU (British Thermal units) of energy per gallon.
Propane is used in homes primarily for heating purposes but is also
used as a source for heating water, drying clothes and cooking - both
in kitchen ranges and barbecue grills.
Although propane is extracted from both crude oil and natural gas,
its price seems to track the price of crude more closely. Propane
consumption generally tends to be seasonal and is higher in
the winter months.
Propane is typically delivered to homes via tanker trucks operated by
independent propane dealers in local markets. Upon delivery it is stored
in above-ground storage tanks which are outside homes. These storage
tanks can hold between 500 & 1000 gallons of propane.
