How Is Oil Turned Into Plastic?

Crude oil is a naturally occurring liquid composed mostly of hydrogen and carbon. Crude oils vary in their composition, but generally range around 20% gasoline and naphtha, 35% gas oil, 20% lube distillate, 20% residuum, and 5% light gasoline. Refinery processes turn low quality material into higher quality products. Plastic manufacturers use processes like refiners, or purchase products to produce the chemicals that are used in synthesizing plastics. Since crude oil contains many molecules, the industry breaks and builds molecules to fill the niche. Fluid Catalytic Cracking (FCC) breaks larger molecules into Gases, Gasoline, Gas oil, and Heavy bottoms. The product streams produced by the FCC contain unsaturated hydrocarbons referred to as olefins. The gases are separated and stored, sold or used in subsequent processes. Of these gases produced, propane is used in the manufacture of cymene
