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.Continue Reading
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
Petrochemicals are organic chemicals made from crude oil and natural gas for use in industrial processes. Examples of primary petrochemicals include methanol, ethylene, propylene, butadiene, benzene, toluene and xylene. Roughly five percent of the world's annual oil supply is utilized to make petrochemicals. These organic substances are used to make plastics, medicines, furniture, appliances, solar panels, PVC pipes, bulletproof vests, consumer electronics, wind turbines and automobile parts.Full Answer >
Gas chromatography works by taking a mixture of gases and moving it through liquid, solid or gas states in order to separate the gases. This process separates the mixture into its different components, which are then processed through a device such as a mass spectrometer, which describes them.Full Answer >
Gas suppliers produce neon, an inert elemental gas that exists in the Earth's atmosphere, as a byproduct of liquefying and separating air in a laboratory through the fractional distillation process. The purified neon is stored in metal gas cylinders, under pressure, as a liquid. Neon forms no naturally occurring compounds and, according to WebElements, 1 part in 65000 of the atmosphere is neon.Full Answer >
Fractional distillation involves boiling crude oil so that the various types of hydrocarbon molecules present vaporize, each in turn. The vapors are then condensed into separate batches according to type.Full Answer >
