About Propane
Tri-Gas strongly promotes customer safety though education about the product and service we provide. Please call our office anytime with questions or concerns you have about propane and your propane service.
C3H8 - The molecular makeup of propane consists of 3 Carbon molecules and 8 Hydrogen molecules.
Propane, also called LPG, liquefied petroleum gas, or LP gas, is a widely used highly efficient and clean burning fuel.  It is transported and stored under pressure as a very cold liquid and can cause "freeze burn"  or frost bite if exposed to skin.  
  In it's natural form propane is colorless and odorless.  In order to make propane easier to detect in the event of a leak or spill manufactures deliberately add a chemical compound, ethyl mercaptan, to give it a distinct order.
Boiling Point - -44°F
Propane Pounds Per Gallon - 4.24 lbs
BTU s per gallon at 60° F - 91,547
BTU s per pound of propane - 21,591
BTU s per cubic foot vapor at 60°F - 2,516
BTU - a British Thermal Unit is the quantity of heat required to raise the temperature of one pound of water by one degree farenheight.
Cubic Foot Vapor per Gallon at 60°F -  36.4
Cubic Foot Vapor per Pound at 60°F -  8.6 
Specific Gravity of Vapor -  1.52
Specific Gravity of liquid -   .51
Specific Gravity of Propane Vapor 
One cubic foot of propane weighs .1162 lbs. and one cubic foot of air weighs .07655. Dividing .1162 by .07655 equals 1.52. What does this mean? Propane is heavier than air and will seek the lowest space available.
Specific Gravity of Liquid Propane
One gallon of propane weighs 4.24 lbs. One gallon of water weighs 8.33 lbs. Dividing 4.24 by 8.33 equals .51. This means propane is less dense than water (lighter than water) and will not sink in water.
Maximum Flame Temperature Propane  - 3595°F
Maximum Flame Temperature Natural Gas -  3000°F
Limits of Flammability -  2.2 - 9.6
Propane Limits of Flammability- The lower and upper limits of flammability are the percentages of propane that must be present in an propane/air mixture. This means that between 2.15 and 9.6% of the total propane/air mixture must be propane in order for it to be combustible. If the mixture is 2% propane and 98% air, there will not be combustion. If the mixture 10% propane and 90% air, combustion will not occur. Any percentage of propane in a propane/air mixture between 2.15% and 9.6% will be sufficient for propane to burn.
Octane Number -  125
Propane is Clean and Efficient
Propane has long been recognized as a "green" energy. By using this low carbon content fuel, homeowners can help cut greenhouse gas emissions, improve air quality, and protect the environment!
  • Propane is an approved alternative fuel listed in both the Clean Air Act of 1990 and the National Energy Policy Act of 1992 and 2005.
  • Propane is nontoxic and insoluble in water. Because it is released as a gas, it doesn't spill, pool, or leave a residue.
  • Propane is produced domestically and can meet today’s energy needs more cleanly and efficiently than many other fuels currently available.
Propane is a Friendly Fuel
  • When burned, propane emits less than half the greenhouse gas emissions as an equivalent amount of electricity produced by coal-fired power plants
             (Energetics, 2007).
  • Propane emits less greenhouse gas emissions than Gasoline, diesel, and electricity in most applications (Energetics, 2007).
  • A traditional propane water heater emits 60 percent fewer greenhouse gas emissions than its electric counterpart.
  • Propane-fueled radiant heat cuts down on dust and allergens in a home since there is no need for a fan or blower.
  • Propane is an approved alternative fuel recognized by the Clean Air Act and the Energy Policy Act of 2005.
