Rijeka oil refinery, Urinj is located at the northern part of the Adriatic Sea, taking up 3.5 square kilometers of coastal area of Kostrena and Bakar, 12 kilometers to the south of Rijeka. It is the shortest and most convenient connection with central Europe and with the Mediterranean. In Rijeka INA has a road, railway, marine and pipeline infrastructurefor supply and shipment of goods, crude oil and petroleum derivates.
Rijeka oil refinery is connected by a sea line – 7.2 km long and 20" in diameter - with the port and petroleum terminal in Omišalj, on the island of Krk (JANAF).
The business activities of INA’s refineries are in accordance with the requirements of international standards of the Quality Management System ISO 9001:2000, Environmental Management Systems ISO 14001:1996 and Health and Safety Management System OHSAS 18001:1999, which have been certified by the awarded certificates.Quality control of INA’s products is carried out by applying modern testing methods in the refinery’s laboratories, in accordance with the Authorization based on the standard HRN EN ISO/IEC 17025:2000 that was granted by the Croatian State Bureau of Standards and Metrology.
The production program of INA’s refineries includes: Liquefied Petroleum Gas, virgin naphtha, motor gasoline, kerosene, aviation turbine fuel, diesel fuels, fuel oil, bunkers and liquid sulphur. The quality of products is regulated by INA’s, Croatian and European standards, and production according to buyers’ special requests, stipulated in contracts, is also an option.
At the ceremony organized on February 12, 2011 in Rijeka Refinery, the completion of the investment project within the first phase of Rijeka Refinery system development were formally put into operation. The first phase included three facilities within Hydrocracking complex and other supporting facilities and installations. The facilities are: Mild hidrocracking, Hydrogen unit and Desulphurization plant (Claus) as well as numerous supporting facilities and installations.
The center facility of the complex is Hydrocracking/Hydrodesuphurization. Through the hydro cracking of heavy hydrocarbons we will get lighter products, and by the hydrodesulphurization of these lighter products - EURO V fuels. Hydrogen unit is designed for supplying of Hidrocracking plant, and other plants if necessary, with high purity hydrogen. Besides hydrogen, the plant produces also high pressure steam that is used for production of electricity. Desulphurization plant, the so-called Claus, is able to isolate at least 99.8% of the sulphur present in the total input. In July 2011, the reduction station for natural gas was installed to enable the natural gas usage as fuel in the Rijeka Refinery.
In February 2014 contract on basic design on Delayed Coking Unit with company Bechtel Hydrocarbon Technical Solutions (BHTS) was signed. This technology has a proven environmental and economic performance on environmentally sensitive locations such as Rijeka. Basic design is a major milestone towards decision on further investments.
