Explosion in Calenzano, here's what the Eni plant is working on

The depot of Calenzano, where the accident of 9 December occurred, carries out reception, deposit (storage) and shipment of petrol, diesel and oil (kerosene). These products arrive at the Calenzano depot via two pipelines connected with the Eni refinery in Livorno, to be then stored in cylindrical atmospheric tanks (with fixed or floating roofs) while waiting to be sent to the loading shelters of the tankers.

This is what emerges from the information on the Eni site in Calenzano taken from the file of the Istituto Superiore per la Protezione e la Ricerca Ambientale (Ispra).
