Propane as an alternative fuel
Propane has been used as an automotive fuel since 1913. Today it is the most popular alternative fuel in the world with more than 4,000,000 vehicles running. In the United States, there are more than 300,000 propane vehicles that use more than 2 billion liters of clean emissions automotive fuel per year and represents 66% of all alternative fuel vehicles and 77% of all alternative fuels used.
Propane is dispensed at an average of 40 to 70 liters per minute. Faster than gasoline and diesel . For propane all charges are fast.
Propane has the highest volumetric efficiency of all alternative fuels, so it offers smaller tanks to achieve a greater range of travel, allowing more payload than any other fuel.
Advantages of the propane vehicle
- Space Saving: The ability to be stored on board as a liquid allows vehicles to carry the same amount of fuel in the equivalent space of traditional fuels.
- Range: The distance traveled is comparable to that of gasoline and better than any other alternative fuel.
- Charging speed: Propane is comparable to that of naphtha when supplied as a liquid. The load capacity can go up to 70 liters per minute.
- Conversion cost: Lower than other alternative fuels.
Propane is obtained from natural gas or gases from cracking processes produced in petrochemical facilities, it is a by-product of natural gas processing and oil refining.
- It is used as fuel, for domestic, commercial use and also in industries, for ovens, dryers, boilers.
- As fuel in internal fuel engines and gas turbines for electricity generation.
- In the chemical industry it is one of the products used for the synthesis of propene
- As refrigerant gas (R290)
- As a propellant gas in aerosols.
