Our refinery in Sannazzaro: a high-efficiency hub

A strategic plant, with one of Europe’s highest conversion capacities.

The plant and its production capacity

The refinery lies on an area of around 320 hectares in the municipalities of Sannazzaro de’ Burgondi and Ferrera Erbognone, in the province of Pavia. It lies in the centre of the industrial triangle between Turin, Milan and Genoa, along the oil pipeline that links the terminal in Genoa with French Switzerland. Such a favourable, carefully chosen position has led to the development of an efficient refuelling and distribution pipeline network, thus leading not only to the effective handling of products, with precise and quicker supplies, but especially a drastic reduction in the environmental impact linked to land transport.

Over the years, the Sannazzaro refinery has been subject to progressive technological improvements. These have led to a production capacity today of 11.1 million tonnes per year of petroleum products, with one of the highest levels of complexity and conversion capacity in Europe. 

Towards total conversion

The oil product market for energy use, from LPG to diesel, consists increasingly of high-quality fuels. To respond to this environmentally-friendly need, heavier products must be transformed into hydrogenated products with a lower environmental footprint.

With this in mind, progressive investments have been made in the Sannazzaro refinery in relation to its production cycle, including:

  • hydrogen production and Hydrocracking plants to maximise diesel production;                      
  • gasification plants, which produce sulphur- and pollutant-free syngas from heavy oil;
  • deasphalting plant, able to recover heavy oil fractions for subsequent conversion to petrol;
  • Eni Slurry Technology (EST) conversion plant. The Eni license process, used to produce fuels from heavy crude oil residues, using a special catalyst developed and patented by us. 

The adoption of these innovative technologies increases the total conversion rate of heavy oils to 92%.
