The Facts About Petrochemicals

By Lenna Stockwell


For most of us, petroleum is a word that conjures up images of going to the gas station to load up our gas tanks with fuel. While petroleum is used as a source of fuel, there are also other important products that are created or derived from petroleum. Petroleum products are all around us, so it is important to have a basic understanding of petroleum and what it's all about.

While we typically mine or drill for petroleum, it actually does seep up from beneath the surface of the ground and has for hundreds of thousands of years. The word petroleum has existed for thousands of years, as well, and is a mix of the Greek words for oil and rock. Before we had cars, petroleum was used as a source of light and even had medicinal uses and possibly was used to create a weapon that was called Greek Fire.

Petroleum is called a hydrocarbon, which is a name that is given to any organic compound that contains only hydrogen and carbon. These carbon atoms and hydrogen atoms combine in different weights to produce the various gases, liquids and solids that you find in petroleum. For example, one of the gases in petroleum is propane, which is a source of fuel for many people around the world. While petroleum is a type of fossil fuel, it is not the fossils of dinosaurs that have created petroleum but rather the fossils of ancient algae and other types of single cell plants and organisms.

Of course, petroleum is used to make a wide variety of fuel, including the gasoline used to power the millions of vehicles with internal combustion engines. Other types of fuel that we get from processing petroleum include jet fuel, diesel fuel, butane and kerosene. Petroleum also is used to make motor oil and oils that are used to lubricate machine parts. Asphalt is another substance derived from petroleum and people have been using asphalt for thousands of years.

Plastic is another important product that is often produced using petrochemicals, or rather chemicals that are taken from petroleum. Many thermoplastics are made out of petrochemicals. Many products are made out of thermoplastics, including a huge variety of retail product packaging such as food packaging, electronic packaging and medical packaging. A thermoforming company designs many types of customized packaging for its clients by heating up large, thin sheets of plastic and molding them into whatever shape is needed by a client.

There are many common forms of plastic derived from petroleum or rather petrochemicals. Polyvinyl chloride, for example, is one type of plastic that we use to make many products and most people simply just know this as PVC. It commonly is used to make pipes, but also used to produce signs, furniture, shower curtains, flooring and much more. Polystyrene is another petroleum-based plastic and is more commonly known as Styrofoam.
