The Ryazan Oil Refinery Company (RORC) is TNK-BP’s biggest refining subsidiary. It produces a wide range of high-quality oil products: AI—80, AI—92, AI—95 and AI—98 motor gasoline, diesel fuel — including low-sulfur Euro-4 and Euro-5 grades — jet fuel, boiler fuel, road and construction bitumens, lubricants and other oil products. The refinery has a capacity of 17 million tons of oil per year.
Production of motor gasoline began at the Ryazan Oil Refinery (which was the company’s official name until July 2002) on 19 October 1960. In 1993, the refinery was turned into a joint-stock company and in 1995 became part of TNK. In 2002, Ryazan Oil Refinery was restructured to form CJSC Ryazan Oil Refining Company, which became part of TNK-BP in 2003.
From 1999 to 2002, Phase 1 of an extensive program of renovation work was carried out, affecting all the company’s main process units, from primary refining to hydro treatment and dispatch. Upgrading work on the three primary oil refining units, including installation of an automatic control system, has resulted in an increase in output of high-quality motor fuel, and improved environmental and safety standards. Two diesel-fuel hydro treatment units have also been modernized and new types of diesel processing have been introduced, and a boiler-house has been built. In 2001, RORC’s central processing unit — the catalytic cracker – was upgraded, boosting its productivity from 900,000 to 2.5 million tons of oil per year.
To reduce its environmental impact and cut hazardous atmospheric emissions the sulfuric acid unit was also upgraded. The selective oil hydro treatment unit was completely renovated, and the hazardous solvent phenol was replaced by a nontoxic biodegradable alternative.
In 2007, in record quick time, the Ryazan Oil Refining Company upgraded 17 of its facilities simultaneously – a unique project in the history of RORC.
In 2008, RORC began producing Euro-5-standad diesel fuel with a sulfur content of no more than 0.001%. Also that year, an ultraviolet effluent disinfection unit was installed in the company’s biological treatment station to make the treatment process more modern, environmental friendly and safe.
