From the beginning, the company located its facilities in the South Industrial Area of Tarragona, of which it is one of the pioneer industries, and specialized its refining activity to obtain asphalt bitumen. The staff was mostly from the territory, especially from the seafaring area of the Serrallo in the city of Tarragona.
The initial installation had a distillation capacity of some 700,000 tons of crude oil, with some 500,000 tons of asphaltic bitumen and the rest of the distillates obtained.
Decade of the 70s
