1. Natural Gas & Propane Raqwan Griffin 3 rd hour

2. What is Natural Gas Natural Gas is a mixture of hydrocarbons, predominantly, methane, ethane, propane and other gas such as nitrogen, helium, carbon dioxide, sulfide, and water vapor. It is delivered through pipelines systems. Natural gas has a high octane rating & excellent properties for spark-ignited combustion engines.

3. Natural Gas  Most natural gas is extracted from gas and oil wells.  Natural Gas is about one quarter of energy used in the united states of all about one third gas goes to residential & commercials uses one third to industrial use and other one third to electric power production and about one tenth of percent is currently used for transportation fuel.

4. Advantage for Natural Gas Nearly 87% of U.S. natural gas used is domestically produced 60-90% less smog-produces pollutants 30-40%less green house emission Less expensive than gasoline

5. Disadvantage for Natural Gas Limited vehicle availability Less readily available then gasoline & diesel Fewer miles on a tank of fuel

6. Renewable or non renewable Natural Gas is an non renewable.

7. About Natural Gas Natural Gas is a fossil fuel comprised mostly of methane it is one of the cleanest burning alternative it can be used in the firm of compressed natural gas or liquefied natural gas to fuel cars & trucks.

8. Natural Gas vehicles Natural Gas vehicles are designed to run on Natural Gas on Natural Gas only, dual fuel or bi-fuel vehicles can also run on gasoline or diesel. There are about 120,000 vehicles powered by Natural Gas 1.8 million of these all over the world

9. What is Propane Propane is an alternative transportation fuel system mainly from its domestic availability and high energy density and clean- burning quantities. It is the world most common engine fuel. Propane is an alternative transportation fuel system mainly from its domestic availability and high energy density and clean- burning quantities. It is the world most common engine fuel. Propane is consider alternative under the energy policy act in 1992. Propane sold as vehicles fuel can be a mixture of propane with small amounts of other gases. Propane is consider alternative under the energy policy act in 1992. Propane sold as vehicles fuel can be a mixture of propane with small amounts of other gases.

10. Propane Propane is a gas at normal temptures & pressure. It stores onboard a vechical in a tank of pressure to around 300 pounds per square inch. A gallon of Propane has about 25% less energy than a gallon of gasoline.

11. Propane efficiently Propane is transformed into a gaseous state before it is burned in an internal combustion engine, the engine runs more efficiently in low-speed light-throttle conditions. Liquid propane injection engines has a high efficiently in fuel.

Liquid propane injection engines has a high efficiently in fuel.

12. Propane Advantages 95% of propane used in the U.S. comes from domestic sources Less expansive than gasoline Potentially lower toxic, carbon dioxide, carbon monoxide, non methane, hydrocarbon

13. Propane Disadvantages Limited availability Less readily available than gasoline & diesel Fewer miles on a tank of fuel

14. How does PROPANE effect the environment Propane is non-toxic, on caustic and will not create an environment hazard it releases liquid or vapor into water or soil If it spills in a large quantity the only environmental damage that may occur is freezing organism or plants life in the immediate area.

15. Renewable or nonrenewable source Propane is non renewable it is obtained from natural gas fields.

16. How is propane transformed into usable energy Propane is a gas at normal temperatures and pressure.

17. Propane cars fuel Fuel cars with propane would be one way to diversity U.S. transportation fuel. Most of propane that is consumed in the U.S. is produced domestically & distributed an established infrastructure cars would reduces U.S. depending on foreign oil increase energy securities.

18. Natural Gas vs. Propane Natural gas is made up of several gases including propane, butane, ethane and mostly consists of methane. While propane is a part of natural gas, it is a hydrocarbon separated from the other gases at gas processing facilities.
