How the plastic pellets are made from the crude oil?
Petroleum is drilled from the earth and transported to an oil refinery for processing.
The crude oil that is removed from the earth gets refined into petrochemicals such as ethane and propane.
Ethane and propane are then used to make the hydrocarbons ethylene and propylene in a heating process known as cracking or catalytic cracking. This process breaks down larger molecules into ethylene or propylene or other types of hydrocarbons.
After the material is cracked, a catalyst is added to a reactor, which creates a powder material called a polymer. This material, which the refineries call “fluff,” is combined with different additives (depending on the type of plastic desired) in a continuous blender.
The polymer solution is then pumped from the mix tank to the flash tank, through a preheater which maintains the polymer solution at the right temperature 90°C +194ºF. The Megaroyal pump continuously injects the polymer solution into the flash tank which feeds the extruder.
Once the extruded material cools it is cut and formed into the plastic pellets. These plastic pellets are the raw material for the plastic industry (for instance, injection molding processing).
