The factory at Puente Mayorga (Spain) is one of the world's biggest producers of linear alkyl benzene (LAB). It possesses UOP's HF technology based on alkylation with hydrofluoric acid and we produce normal paraffins, linear alkyl benzene (LAB), heavy alkylate (HAB), and sulphonic acid (LABSA). The raw materials - kerosene, hydrogen and benzene - come directly from our Gibraltar-San Roque refinery. The plant also returns the hydrogenated kerosene to the refinery without the normal paraffin, making it an excellent fuel for aviation reactors. In 2020, it will be the first plant in the world to replace its HF technology with Detal flex 2-phenyl, developed by Cepsa and UOP, becoming a more modern and efficient plant.
