The Group carries out its oil refining activities at the Sarroch industrial site, managed by the subsidiary Sarlux and located on the south-western coast of Sardinia. The processing capacity of 15 million tonnes per year (300,000 barrels per day) accounts for about 20% of the Italian refining capacity.
Our refinery is one of the largest in Europe and one of the most advanced in terms of plant complexity.
These characteristics are the result of decades of investments aimed at increasing capacity and efficiency, combined with an attention for safety and respect for the environment.
In 2015, Sarlux acquired the adjacent petrochemical facilities owned by Versalis (ENI Group), thus expanding its range of products to include certain categories of aromatics and intermediates in the petrochemical supply chain.

Logistics
The logistics facilities include over 4.3 million cubic metres of storage tanks.
Raw materials processed
The geographical position in the middle of the Med has strategic importance, as it gives easy access to the sources of crude oil and to the markets of destination of finished products.
RAW MATERIALS BY ORIGIN
One of the main strengths of the Sarroch refinery is its great flexibility and ability to use different types of crude oil, including non-conventional ones, exploiting market opportunities and differentials in price thanks to its commercial and trading skills.
RAW MATERIALS BY TYPE
| 2023 | ||
|---|---|---|
| Light extra sweet | 47% | |
| Light sweet | 10% | |
| Medium sweet/extra sweet | 1% | |
| Medium sour | 1% | |
| Heavy sour/sweet | 40% | |
| Densità media del grezzo | °API | 33.3% |
Products
As regards the refined products yield, in 2023, consistently with the production set-ups characterized by the shutdowns of some plants, the percentage yields in middle distillates decreased in favor of higher production of semi-finished products, fuel oil and naphtha.
