San Roque: CEPSA starts up new linear alkylbenzene production process

CEPSA has intensified its commitment to innovation, safety and sustainability by launching operations at the first European chemical plant to use Detal technology in San Roque (Cádiz).

It is also the first Linear Alkylbenzene (LAB) plant in the world to replace hydrofluoric acid (HF) technology with Detal technology, a safer, more efficient and sustainable process which optimizes the efficient use of raw materials and electricity and reduces emissions and waste generation (1,100 tons per year).

The application of this technology, whose patent has been developed by CEPSA in collaboration with UOP (Universal Oil Products), has led to the creation of 250 jobs in the Campo de Gibraltar, reaching 600 in some phases of the process, with more than 800,000 hours invested in engineering and construction and the support of fifty auxiliary companies, most of them from the province.


The main economic activities are tourism and manufacturing.

The CEPSA Gibraltar-San Roque Refinery is the largest in the Iberian Peninsula, with a crude oil daily processing capacity of 240,000 barrels per day (Wikipedia).
