Road tar is made from a mixture of hydrocarbons produced by processing crude oil or natural gas. Bitumen is the remnant of crude oil after the gasoline, kerosene, diesel oil and other fuels have been removed.
Bitumen is solid at low temperatures, but turns into a liquid at high temperatures. Tar is usually applied while hot so that it flows down into road cracks easily. Once cooled it turns into a semisolid substance. On days with a high ambient temperature tar becomes soft, and can become loose and pull away from the roads. This leads to the oil contained inside the tar being sprayed onto the lower panels of vehicles passing over them.Learn More
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.Full Answer >
Plastic is derived from organic substances including crude oil, salt, cellulose, coal and natural gas. Crude oil, one of the main ingredients of plastic, is a complex compound that must be broken down into fractions (mixtures of compounds made up of carbon and hydrogen) in order to be used effectively.Full Answer >
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 >
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 >
