General process information
Crude oil is transported to the refinery in order to break it down to several products.
The crude oil is heated in a distillation tower to produce:
Heavy distillates including Naphta, Light distillates (petrol for cars), Kerosene (for aircraft), Diesel, Heating oil and others
Naphta is the base for producing plastic products.
Naphta is heated again in a process called steam-cracking at a temperature of 800°C which breaks it down further into a number of products like Ethylene, Propelyne, Styrene, Benzine and others.
Ethylene, Propylene, Styrene are then going to a process called Polymerization catalysts to be boned together and create Polyethylene, Polypropylene and Polystyrene in the form of granules.
