Refining

Committed to efficiency and value creation

Our commitment to innovation allows us to have pioneering refining assets in terms of technology, which makes them more efficient and safe. Furthermore, the location of our industrial complexes has an important logistical advantage, since they provide access to the two most important European distribution points: the Atlantic Ocean and the Mediterranean Sea.

How the refining process works

We use chemical and physical processes to transform crude and other raw materials into higher quality products with greater added value to be marketed.

  • Pipelines

The crude oil obtained from wells around the world travels to our industrial complexes by sea or in pipelines. After it has arrived, it is analyzed and sent to different areas of the refinery for processing. 

  • Physical separation of the hydrocarbons

The first stage in processing crude oil consists in physically separating the hydrocarbons found in the oil according to their boiling point. Then, the crude oil is fed into a distillation column where it is heated at high temperatures. Later, the lighter components, such as gases, rise to the top of the column while the heavier ones, such as lubricants and bitumens, stay at the bottom. Even though we tend to think of gasoline or diesel, there's a lot more we can obtain from crude oil. Tires, asphalts, plastics, containers, and numerous other products have one thing in common: they all came from an oil barrel.
