Gas comes from crude oil. The remains of organisms that lived on Earth hundreds of millions of years ago were eventually covered with sediment and rock. The pressure and heat of the Earth caused the remains and sediment to combine and create liquid hydrocarbon, or crude oil.Know More
Refineries break down the hydrocarbons into many different products. The refiners do this through a distillation process. The crude oil is heated and put into a still where different hydrocarbons boil off and condense at different temperatures. The hydrocarbons are collected after condensing. Distillation is followed by additional processing. Cracking is a process that breaks down heavy hydrocarbon molecules into light hydrocarbon molecules by using heat, pressure and sometimes a catalyst. Using a catalyst increases the chemical reaction, producing more gasoline from the process.
Gasoline is the most produced product because it is the most used product. The characteristics of the end product depend on the crude oil used and the refinery’s methods. Some other popular products made from crude oil are diesel fuel, heating oil, jet fuel and liquefied petroleum gas, or LPG. A 42-gallon drum of crude oil produces 44 gallons of petroleum products. From one barrel, a refinery creates 19.7 gallons of gasoline, 10 gallons of diesel fuel or heating oil, 4 gallons of jet fuel, 1.8 gallons of heavy oil and 1.8 gallons of LPG, and the remaining 7.3 gallons is used for other petroleum products.Learn more about Chemistry
Propane is separated from crude oil during the refining process and extracted from natural gas at a gas processing plant. It is considered a fossil fuel because it was formed from the remains of sea animals and plants. When living organisms die and sink to the bottom of the sea, sand and silt cover them, subjecting the remains to high pressure and heat, which change the chemical makeup.Full Answer >
Gasoline and diesel fuel are both used to power automobiles and machinery. They are both the product of crude oil, but they are different because they are not able to power engines in the same way.Full Answer >
Motorized vehicles run on gasoline because crude oil became cheaper to refine than making grain alcohol from plants, according to National Geographic. In the early 1930s, a gallon of gasoline cost 10 to 13 cents, whereas a gallon of ethanol was 25 cents, notes historian Bill Kovarik, Ph.D.Full Answer >
Petrol is made from crude oil by removing hydrocarbons and carbon atom chains through a process known as distillation. Usually, this process takes place at an oil refinery. Distilling petrol relies on gradually increasing the temperature of crude oil to break apart and get rid of these chains. The product that is left behind is a pure and usable form of petrol.Full Answer >
