Rijeka Oil Refinery The Rijeka Oil Refinery started its operation in 1883 as the largest oil refining plant on the mainland. With an annual refining capacity of 60 thousand tonnes, it remained the largest for approximately next ten years. It was built in the suburban area called Ponsal (today Mlaka), simultaneously with the construction of the Petroleum Harbour. It met one third of the oil products demand of the Austro-Hungarian Empire. Unlike typical refineries of that time, which operated as manufactories with 10 to 20 workers and without the supervision of an expert, Rijeka started its production with 300 employees and a technical director who was a highly qualified chemist. Thus, it became the first European industrial oil refining plant. When the City of Rijeka became a part of the territory of the Kingdom of Italy at the end of the First World War, the Refinery acquired a core role in the state oil programme. In 1922 it was known as Raffineria di Olli Minerali S.A., and in 1926 it became the first industrial facility of the Agip Company. Thus, Rijeka became the “birthplace” of the oil industries of the two European Union members, first Hungary, and then Italy. At the beginning of the Second World War, its capacity was 120 thousand tonnes. After the war, as a part of the territory of Yugoslavia, first destroyed and then reconstructed, the Refinery became the most important oil processing plant in the country. In 1965, owing to new process units at Urinj, it had a refining capacity of 8 million tonnes. At that time, the Mlaka plant was specialised in the production of lubricants, while the Urinj plant specialised in the production of fuels. The Refinery had a leading position on the market and in regard to technology in Yugoslavia. During the 1980s, 250 types of oil products were produced in Rijeka and in 1984 the first unleaded petrol in the former state was produced. The Refinery played an important role in the creation of the Republic of Croatia, as an oil product supplier for Croatia in the 1990s during the Homeland War. At the ceremony organized on February 12, 2011 in Rijeka Refinery, the completion of the investment project of three facilities within Hydrocracking complex: Mild hidrocracking, Hydrogen unit and Desulphurization plant (Claus) as well as numerous supporting facilities and installations were completed. 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. Sisak Oil Refinery Sisak Oil Refinery developed from a Shell storage facility built in 1923 on the spot where the Kupa River joins the Sava River. In 1927, at the same location, Shell built a boiler distillation with a daily refining capacity of 170 tonnes. Feedstock and material were transported by barges along the Sava River and railway tank cars. The refining of domestic oil began in 1940. At the time, 96 thousand tonnes of oil was refined at the refinery and two hundred types of oil products produced. During the Second World War, the plant was seriously damaged. The production was restored in September 1945 and the pre-war production levels were exceeded as early as 1949. A new development cycle started with the construction of a modern Combined Process Unit I. It was put into operation in 1956 with a daily capacity of 100 tonnes. Iraqi oil was the dominant feedstock. After the construction of the Stružec-Sisak oil pipeline in 1960, priority was given to oil from oil wells in Slavonia and Moslavina. In 1961, the construction of Combined Process Unit II was initiated. As a result of that, in 1964, the Refinery managed to produce over one million tonnes of oil, becoming the first in the country to do so, and it also initiated production of 98 octane petrol. Continuous construction of new process units eventually led to a technological peak in the mid-1980s when the refining capacity was 6.7 million tonnes. During the Homeland War the Refinery was only a few kilometres away from the first line of fire, which unavoidably resulted in the destruction of refinery units. Restoration of the production and new requirements in regard to the quality of products raised a question about a new investment cycle. As a part of refinery system development, in Sisak refinery three plants have been completed: desulphurization plant, the so-called Claus the hydrodesulphurization of FCC gasoline plant and Isomerization plant. Refinery has a possibility of production of diesel fuels with bio component from mid-2013 and same year in September a system of additional wastewater treatment KROFTA was put into operation. In April 2014, installation of new coke chambers was carried out at the Coking plant. Over the past few years, INA has invested more than HRK 1 billion in the Refinery, thanks to which new processing units were built in order to provide modern standards of crude oil refining and production of motor fuels in line with Croatian and European conditions. The goal of these investments is to increased health, safety and environment protection and improve efficiency in the Refinery.

Rafinerija nafte Sisak kontinentalna je rafinerija, smještena 50 kilometara južno od Zagreba. Nalazi se na križanju cestovnih, željezničkih i riječnih putova, blizu domaćih naftnih polja. Uz domaću, prerađuje i uvoznu sirovinu, kojom se snabdijeva Jadranskim naftovodom iz dva smjera - Mediterana i Rusije. Lokalnim naftovodom transportiraju se nafta i kondenzat iz domaćih nalazišta u Moslavini, a rijekom Savom nafta sa slavonskih naftnih polja. Rijeka Sava predstavlja spoj s istočnim tržištem, a blizina transportnog koridora Zapadna Europa – Zagreb – Beograd – Srednji istok, jedna je od prednosti geografskog položaja ove rafinerije. Rafinerija nafte Sisak kompleksna je rafinerija s dobro odabranom tehnologijom. Raspolaže velikim skladišnim prostorom, suvremenim instalacijama za otpremu proizvoda, riječnom lukom s tri pristana za dopremu nafte i otpremu derivata. Rafinerija nafte Sisak može se pohvaliti prvim integriranim sustavom upravljanja u Hrvatskoj. Kvalitetom svojih proizvoda, Rafinerija Sisak zadovoljava europske standarde. U sklopu razvoja Ininog rafinerijskog sustava, u Rafineriji nafte Sisak izgrađena su tri postrojenja: postrojenje za izdvajanje sumpora ( tzv. Claus postrojenje), postrojenje za hidrodesulfurizaciju FCC i Postrojenje Izomerizacije. U rujnu 2007. godine pušteno je u rad Postrojenje za odsumporavanje (Claus), čiji je ekološki učinak maksimalno smanjenje emisija sumporovodika i sumporovog dioksida iz sustava rafinerijskog loživog plina. Utjecaj rada Clausa na smanjenje imisijskih koncentracija ovih plinova u okruženju vidljiv je iz podataka koji kažu da je koncentracija SO2 smanjenja za 50,9%, a H2S za 12,5% u odnosu na ranije. U rad je 2009. pušteno i postrojenje HDS FCC benzina (hidrodesulfurizacija FCC benzina), a 2011. pušteno je u rad i Postrojenje za izomerizaciju. Rafinerija od sredine 2013. godine ima mogućnost proizvodnje dizelskih goriva s bio komponentom, a u rujnu iste godine je u rad pušten sustav dodatne obrade otpadnih voda KROFTA. U travnju 2014. izvršena je montaža novih koksnih komora na Koking postrojenju. U posljednjih nekoliko godina INA je uložila više od milijardu kuna u razvoj Rafinerije zahvaljujući čemu su izgrađene nove procesne jedinice s ciljem osiguranja suvremenih standarda prerade sirove nafte i proizvodnje motornih goriva u skladu s hrvatskim i europskim uvjetima. Cilj ulaganja je povećanje zaštite zdravlja, sigurnosti i okoliša i poboljšanje učinkovitosti u Rafineriji.
