Euro 4 and Euro 5 fuels are fuels that meet current European Union restrictions on emissions. In order to produce these fuels, the plant has spent 13.5 billion tenge (US $87 million) to modernize its equipment. At the end of 2013, the plant commissioned a nitrogen-oxygen station with two cryogenic tanks of 50 and 20 cubic metres to store liquid nitrogen and oxygen. Two new 20 thousand cubic metre tanks for crude oil are also being installed. Their construction will be completed by the end of 2014.
The updated equipment and improved production management allowed the plant to refine 5.09 million tons of oil in 2013, 1.8 percent more than the previous year. The company hopes to reach an annual refining volume of 7 million tons and to start producing Euro 4 and Euro 5 fuels by 2016.
