Cepsa is upgrading one of its most emblematic chemical plants, located in Puente Mayorga (Cadiz, Spain), making it the first linear alkyl benzene (LAB) facility in the world to replace hydrofluoric (HF) technology with the Detal process, resulting in a more efficient and sustainable operation.

The company presented this project at CESIO 2019, the largest international surfactant congress. With an investment of $113.41mn, Cepsa plans to revitalise the plant, making it the first in Europe and the second in the world to use a fixed-bed Detal catalyst (the first plant to have this innovation was the company's Canadian facility).

The new plant will be completed in 2020. The new technology will allow production of all commercial LAB grades (high and low 2-phenyl) in the same installation, with total flexibility, depending on the demand. This versatility allows the company to meet the specific demands of each client. Detal technology, in addition to improving the quality of the product, will increase the efficiency of the plant and reduce its emissions, since it requires lower consumption of natural gas and electricity.

Furthermore, the digital transformation programmes designed by the company will also be installed. The YET (Yield, Energy and Throughput) system, an artificial intelligence programme and the application of Industry 4.0 technologies (machine learning, big data and advanced analytics), will optimise processes and improve the plant's energy efficiency.

This process will also allow the plant’s LAB production capacity to increase by 50,000 tonnes (a 25% increase), with the aim of supplying the growing consumption of emerging economies in Africa. The company estimates that between now and 2035, the demand for LAB in these countries will grow by 5% annually.

During the presentation of the project at CESIO 2019, Salvador García Claros, director of development and innovation of the chemical area of Cepsa, pointed out: "We are world leaders in both the production of LAB and the development of the best technology to produce it, used in more than 80% of the new plants that are built worldwide. Our experience and leadership have now led us to be the first to install Detal technology in a plant built for HF. We are convinced that this upgrade will bring greater competitiveness to this plant, as well as increasing our capacity to meet the growing surfactants demand.”

LAB is the precursor to linear alkylbenzene sulfonate (LAS), the world's most widely used biodegradable surfactant in laundry detergents. LAS was launched more than half a century ago and its excellent properties make it a necessary ingredient both in traditional detergent formats (powder, or detergent bars) and in more sophisticated products (single-dose capsules, or high-concentration liquid detergents).
