Topics to be Covered • Petroleum History • Technological Aspects • Gasoline • Environmental Impacts
Petroleum History • Commercial Production History • Oil Price History
Commercial Production History • 1900’s. Automobiles with gasoline-burning engines • Early 1920’s. Petrochemical industry was born. Aviation fuel, synthetic rubber, pesticides, fertilizers, plastics, nylon, among others. “We areliving at the peak of the age of Petroleum” Source: API • 1723. Became important → Peter the Great of Russia conquered Baku (Persia). Condition: Profits to the crown • Before 1800’s. Americans skimmed oil to obtain kerosene • 1854. Invention of the kerosene lamp → Formation of the first American oil company (in PA). Seneca Oil Company • 1859 “Boom”-Titusville (PA) . Drake’s well
Oil Price History Strong Economy in Asia
Petroleum Technological Aspects What is Petroleum ? Properties of petroleum Products from petroleum Petroleum refinery
What is Petroleum? • Petroleum, also known as Crude Oil ,is occurring brown to black flammable liquid. • Mainly constituted of hydrocarbons mixed with variable amount of sulfur, nitrogen, oxygen and metal (such as V,Ni) compounds. • 100,000 to1,000,000 different compounds
Mainly properties of petroleum • API gravity • Most commonly crude oil in the rang 20~45 • Higher API, more paraffine, higher yields of gasoline • Sulfur, wet % • Sour is S% > 1, Sweet is <0.5 • Viscosity at 100°F

Technical features • Convert heavier products into lighter ones into gasoline, Such as thermal cracking,coking, viscosity breaking, catalytic cracking, and hydrocracking • Combining lighter products into heavier ones, such as butane and propylene into alkylate , a high-octane gasoline component,such as alkylation and polymerization • Rearranging the molecular structure to improve desirable qualities,such as reforming low-octane gasoline into high octane, such as catalytic reforming and isomerization • Treating, to remove contaminants such as sulfur and nitrogen
What is Gasoline? • A fuel designed for SIE’s • Mixture of Hydrocarbon, (over 500)1, plus additives. • 1 B. Hamilton, FAQ: Automotive Gasoline
History of Gasoline: • Coal tar distillates: Late 19th century. • Gasoline from Petroleum: Early 20th century. • Typical mid-1920s gasoline was 40 - 60 Octane. • 1950s: compression ratio increase, requiring higher octane fuels: Leaded was introduced. • 1970s: leaded was prohibited. • 1970-1990: slow changes in gasoline as lead was phased-out. • 1990 + : the US Clean Air Act started forcing major compositional changes on gasoline. • These changes will continue into the 21st Century.
What is Knocking? • The sound of abnormal combustion.
Can Knocking Harm My Engine? • Light Knocking won’t harm an engine. • Heavy or prolonged can result in engine damage. • What is Octane? • A measure of the ability of gasoline to resist knock.
What Octane Number Should I use in My Vehicle? • Check your owner’s manual. • How Can I stop my Vehicle from Knocking? • Have a mechanic determine whether your engine is in tune. • If it is: Use a gasoline with a higher AKI. • Use after-market deposit control additives. • What Will Happen If I Use the Wrong Octane Gasoline in My Vehicle? • AKI lower than that required by your vehicle: Knock • AKI higher than that required by your vehicle: WASTE OF MONEY.
Will Premium Gasoline (93+) Give Better Fuel Economy than Regular? • Premium has a slightly higher heating value than regular. • Thus, provided more power and better fuel economy!!! • The difference is less than 1% better (Does it offset premium’s higher cost?) • The simple answer is : NO! • What Can I Do to Get Better Fuel Economy? • Good Fuel Economy = Good vehicle maintenance + Sensible driving. • Maintenance: Tuned Engine, clean air filter, aligned and balanced front wheels, and tires with correct air pressure. • Sensible Driving: smooth, steady acceleration, not idling the engine when it could be turned off.
Are Brands Different? • Yes (Gasoline Additive Packages are Different). • Do I Need to Add an After-market Deposit Control Additive to the Gasoline in My Fuel Tank? • Depends on the quality of the deposit control additive in the gasoline (hard to know). • Add a deposit control every 3000 miles.
Safety Tips • Turn Off Engine • Do Not Smoke • Petroleum Equipment Institute is working on a campaign to try and make people aware of fires as a result of "static" at gas pumps. It has researched 150 cases of these fires. Results were very surprising:
1) Out of 150 cases, almost all of them were women. • 2) Most men never get back in their vehicle until completely finished. This is why they are seldom involved in these types of fires. • 3) Almost all cases involved the person getting back in their vehicle while the nozzle was still pumping gas.
4) Don't ever use cell phones when pumping gas. • 5) It is the vapors that come out of the gas that cause the fire, when connected with static charges. • 6) There were 29 fires where the vehicle was reentered and the nozzle was touched during refueling from a variety of makes and models. • 7) Seventeen fires that occurred before, during or immediately after the gas cap was removed and before fueling began. • Source: Petroleum Equipment Institute
Environmental Impacts Oil Spills Car Emissions
Environmental Impacts • Oil Spills • Almost 14,000 oil spills are reported each year • Most spills are contained by spiller, local and state agencies are available to help • EPA in spills occurring in inland waters • Coast guard lead response team in coastal waters • http://www.epa.gpv/oilspill/response.htm
Response Techniques • Mechanical Containment • Booms • Barriers • Skimmers • Sorbent Materials • These are used to contain until oil can be disposed of properly • http://www.epa.gov/oilspill/oiltech.htm
Chemical and Biological • Dispersants • Gelling Agents • Used to keep oil from reaching shoreline • Biodegradation • Microorganisms such as bacteria, fungi and yeast removes oil from aquatic environment • May take years • www.epa.gov/oilspill/bioagnts.htm
Other Methods of Clean Up • Physical Methods • Wiping with sorbent • Pressure washing • Raking • Scare Tactics • Used to protect birds and animals • Propane Scare Cans • Dummies, balloons • www.epa.gov/oilspill/oiltech.htm
Exxon Valdez • 24 March 1989 • Oil Tanker struck Bligh Reef in Prince William Sound, Alaska • 11 million gallons of crude oil were spilled • Largest in US history • Spill posed threats to food chain, which supported commercial fishing industry • www.epa.gov/oilspill/exxon.htm
Transportation • In 1990 85% of transportation was by highway travel • 50% rise in traveling was offset by a 34% increase in efficiency since 1969 • www.eia.doe.gov/alternate/page/environment/chap3.html
AP-42 • A way to estimate emissions • Published by EPA based upon previous experience Sources and Control of Air Pollution
AP-42 and Owners Manual Emissions for Ford Focus
How much does my car emit? • Only has 2000-2003 • My car emits 7.9-11.8 lbs of smog per 15,000 miles and scored a 7 • 26/32 • Volkswagen Jetta scored 1 • 43.7-58.8 lbs of smog per 15,000 • 34/45 • Nissan Sentra scored 10 • 0-1 lb of smog per 15,000 • 28/35 • www.epa.gov/autoemissions/allsmcar-02.htm
