The Angarsk refinery was commissioned in 1955 and acquired by Rosneft in May 2007. The refinery ranks among the largest Russian oil processing plants and is a major petroleum product supplier in Siberia and the Far East.
The plant’s crude distillation capacity currently amounts to 80.5 mln barrels (11.0 mln tonnes) per year. Angarsk Refinery processes West Siberian crude oil delivered via the Transneft pipeline system. Prior to its acquisition by Rosneft, Angarsk Refinery processed substantial volumes of the Company’s crude oil under tolling arrangements.
The plant’s conversion facilities include catalytic cracking, delayed coking, reforming, gasoline and diesel fuel hydrotreatment, and bitumen production units. Angarsk Refinery benefits from extensive use of secondary processes and currently has a relatively high refining depth of over 75.5%. The plant produces more than 200 types of petroleum products, including gasoline, diesel fuel, jet fuel, as well as bitumen, coke, and oils of various grades. Petroleum products from the refinery are sold in the domestic market and exported to 14 countries worldwide.
The refinery also provides 600–700 thousand tonnes of naphtha annually as a raw material for the thermal decomposition unit of the Angarsk polymer plant, which produces a wide range of petrochemical products, and is owned and operated by Rosneft.
A total of 9.53 million tonnes of oil were processed at the Angarsk refinery in 2009, which is equal to volumes in 2008. Saleable product output was 8.74 million tonnes (including output from the Angarsk Polymer Plant).
Measures implemented in 2009 reduced irretrievable losses from 1.21% of refinery throughput in 2008 to 0.96% in 2009, and fuel use was reduced from 7.12% to 6.53% of throughput.
Following the plant acquisition in May 2007, Rosneft took control over further upgrading its production infrastructure.
A comprehensive modernization program was implemented at the refinery in 2009 in order to achieve compliance with government technical regulations for fuel. Construction work was carried out on an isomerisation complex, which is due to be commissioned at the end of 2010, and there was progress with design of alkylation and diesel fuel hydrotreatment units.
Implementation of all these measures will enable production of high-quality fuels to Euro-4 and Euro-5 standards.
An assembly for immixture of additives was completed in 2009, and rebuilding work was carried out on a unit for production of sulphuric acid, to be used for processing of hydrogen sulphide (a by-product of hydrotreatment processes in production of diesel fuels and lubricants).
