Rosneft produces the major part of petrochemical products at the petrochemical block of the Angarsk refinery (Angarsk polymer plant). Simple petrochemical products are also produced at other Rosneft’s refineries.

Angarsk polymer is the only full-cycle petrochemical plant in Eastern Siberia. Annual production is 200,000 tonnes of ethylene, 100,000 tonnes of propylene and 60,000 tonnes of benzene. Most of the ethylene output is used internally to produce high-density polyethylene, styrene and polystyrene. The plant’s inputs are straight-run gasoline and hydrocarbon gases, mainly produced by the Angarsk refinery.


Implementation began in 2010 when contracts were made with tender competition winners for purchase of licenses and project design for the ethylene facility, and also for installation of the new polyethylene and polypropylene facilities.

The Angarsk Polymer Plant processed 703,500 tonnes of inputs and produced 442,800 tonnes of saleable products in 2010, of which 113,400 tonnes of ethylene, 63,700 tonnes of propylene, 71,000 tonnes of high-density polyethylene, 20,200 tonnes of styrol, 13,500 tonnes of polystyrene, 37,400 tonnes of benzene, and others.


A modernization concept for the plant was designed in 2008 with assistance from Nexant, a leading A modernization program was devised in 2008 jointly with leading petrochemical consulting company Nexant, for upgrading of the pyrolysis unit to increase its capacity by 1.5 times to 450,000 tonnes of ethylene per year, together with installation of Russia’s biggest low-pressure polyethylene facility with 345,000 tonnes annual capacity, creation of the country’s second biggest polypropylene capacities (250,000 tonnes of a broad range of polymers), and a railway loading facility for liquefied hydrocarbon gases with 600,000 tonne annual capacity, which will reduce spending on inputs.
