Also known as:
Sannazzaro is a large, medium complexity refinery in Northern Italy just southwest of Milan in Pavia Province in the Po Valley.
The refinery is owned and operated by Eni.
The refinery is located along the oil pipeline that runs from the Port of Genoa through Northern Italy and into Switzerland.
The refinery primarily supplies product to the industrial region around Turin, Genoa and Milan.
Crude is primarily sourced by ship from across the Mediterranean market. There is also a pipeline for movement of domestic crude produced at Villafortuna (near Trecate).
Eni is currently evaluating conversion of the refinery to biofuels production.
Complexity: 11.5
Sannazaro is a medium complexity refinery with upgrading primarily from resid hydrocracking, RCC, Visbreaking, SDA, and resid gasification. It is capable of producing zero resid.
