The Sarlux plants in Sarroch supply the whole of Sardinia with fuels and electricity (covering about 35% of Sardinia’s demand). They produce daily use products for households (fuels, electricity) and for industrial use.
The raw materials (crude oil and fuel oils) delivered to the plant for processing mainly come from the Mediterranean area (North Africa and the Middle East), the former Soviet Union, western Africa and northern Europe. In particular, the flexibility of the Sarlux plant makes it possible to process up to 40 different types of crude oil from over 90 different countries. This characteristic places the Sarroch site at the forefront on the global refining scene.
Oil production has a high output of middle distillates (diesel) and light oil products (LPG, gasoline and virgin naphtha), which in 2013 accounted for around 83% of total production.
The refinery’s products are mainly delivered to the central and western Mediterranean region.
The IGCC power station produces electricity, steam, hydrogen, sulphur and filter cake. The entire production of electricity is delivered to the national grid (operated by GSE). Steam and hydrogen serve the refining plants. The filter cake is used in the pharma, paint, aeronautical and metallurgical industries. The sulphur recovered from the syngas production process has various uses: in the chemical sector (hydrogen sulphide for batteries), in agriculture (fertilisers and insecticides) and in the pharma industry.
Sulphur content is a key indicator of the environmental quality of products. Low sulphur content means that fuels have less of an impact on the atmosphere. Throughout the entire process, from selecting raw materials to fitting efficient desulphurisation systems, Sarlux has always adopted the best techniques to enhance environmental sustainability; the investments made have greatly improved the plant’s desulphurisation capacity.
The Saras group refinery was one of the first in Italy to eliminate lead from the processing of gasoline, before this became required by law. This was mostly thanks to the plant constructed in 1983, Catalytic Reforming (CCR), which made the use of lead superfluous. We implemented a number of other measures to improve product quality and environmental compatibility before they became required by law; one example is the use of double-hull tankers.
