Isab S.R.L.

ISAB's refining, gasification and electricity cogeneration plants, included in the petrochemical of Priolo Gargallo (located in Sicily, between Catania and Syracuse), represent one of the largest industrial sites in Europe, both in terms of size and in terms of complexity, and consist of three production sites called "SOUTH Plants", "NORTH Plants" and "IGCC Plant" (Integrated Gasification Combined Cycle), interconnected each other through a system of pipelines. The processing capacity of the refining plants is 320 thousand barrels per day, while the storage capacity is 4 million cubic meters of products and raw materials. The I.G.C.C. plant generates electric energy by means of a power station with a capacity of 532 MW, which uses as fuel the gas produced from the gasification of the TAR. The gasification plant allows to use one million tons/year of TAR generated by refinery plants, transforming it into synthesis gas, from which are extracted sulfur and other components. The gas, so purified, is then sent to a system of combined cycle turbines for the production of electricity and steam. The plant produces about 4 TWh/year of electric energy, representing 2% of the Italian national production. Today, the Refinery is in continuous evolution, with the construction of new facilities, improving the efficiency of existing ones, and this has made it possible to meet the challenges of the market, improving the quality of products and also decreasing the emission of pollutants into the atmosphere. As evidence of the above, the Refinery has obtained the certificates issued by independent third parties in accordance with the following international standards: ISO 14001:2004 for our Environmental Management System; BS OHSAS 18001:2007 for our Occupational Health and Safety Management System; ISO 50001:2011 for our Energy Management System; ISO 9001:2015 for our supply by sea and storage of raw materials, blending and storage of finished products, products loading and shipping by sea and laboratory activities. Today over 1,000 people are operating on these sites.
