Slavneft-YANOS PJSC (YANOS) is one of the largest refineries in Russia. The Refinery was put into operation in 1961; now it is among the industry leaders that manufactures the high-quality products. The average raw hydrocarbons refining capacity of Slavneft-YANOS is equal to 15.0 MTA.

YANOS manufactures a wide range of petroleum products, including Euro-5 motor gasoline and diesel oil, aviation kerosene, jet fuel, lube oils, bitumen, paraffins and waxes, aromatic hydrocarbons, liquefied gases and furnace oil. Slavneft-YANOS was awarded the Prize of the Russian Federation Government for great achievements in enhancement of the product quality and introduction of the effective management methods.

Due to the ISO 9001:2015 quality management system, YANOS can continuously improve consumer properties of petroleum products. YANOS regularly upgrades the production facilities, increases the operations safety and decreases the adverse impact on the environment. Over the past years, more than two tens of major refining facilities were revamped and built; thus, a high-end deep oil processing plant, consisting of hydro-cracking, visbreaking and catalytic reforming units, was constructed.

In 2005, YANOS became the first Russian refinery to master production of Premium Euro-95 gasoline and diesel oil with the sulfur content of 50 ppm (Euro-4 standard). In 2006, the Refinery proceeded with fabrication of eco-friendly EN 590 diesel oil with the ultra-low sulfur content of 10 ppm. In 2011, YANOS completed construction of the Izomalk С5-С6 Fraction Isomerization Unit and Cat-Cracked Gasoline Hydrotreatment Unit. Implementation of these projects allowed the Refinery fully switching to fabrication of all motor fuels (motor gasoline and diesel oil) in compliance with the Euro-5 standard in 2012.

As a part of the development program, the Refinery commissioned the Diesel Oil Hydrotreatment Unit with the capacity of 1.6 MTA in 2013. In 2014, YANOS revamped the Gasoline Pool Units (1A-1M Catalytic Cracking Unit, MTBE Production Unit and Sulfuric Acid Alkylation Unit) and introduced the diesel oil dewaxing technology for improving the cold flow properties of winter fuel.

In 2015 – 2017, the Refinery commissioned the automated station for diesel oil/ kerosene on-spot loading into rail tank cars, the station of fuel oil on-spot loading into rail tank cars. Thus, the Enterprise completely switched to the environmentally safe system of petroleum products loading. YANOS also commissioned the Group III Base Oils Production Unit. The Unit with the capacity of 100 thousand tons per year is designed to manufacture four types of the high-end base oils, two of which have never been produced in Russia before.

In 2020, Slavneft-YANOS commissioned the MK-2 Wet Catalysis Unit designed for hydrogen sulfide recovery and sulfuric acid production. This new process unit complies with the highest occupational and environmental safety standards.

At present, YANOS is implementing the program of development until 2035, which first stage is construction of the new deep oil-processing complex. The delayed coking process was selected to be the main process. Fulfillment of this and other investment projects will facilitate the Refinery to increase the oil processing depth indicators and yield of light oils, enhance the process performance and optimize the operational expenditures.

Slavneft-YANOS PJSC is a continuous participant of the All-Russia competition named “Russia’s Top 100 Goods”. For recent years, many types of Refinery’s products have been awarded the prestigious prizes in different nominations. In 2020, RON-92-K5 unleaded gasoline became the competition winner, and TS-1 jet fuel won in the “Non-Consumer Goods” nomination.  

The YANOS team also became the prize winner in the International Competition of Scientific, Scientific and Engineering, Innovation Developments held by the RF Ministry of Energy. Competition experts assessed highly the unique technology of winter diesel oil production developed and improved by Refinery’s specialists.  

Commitment to the environment and efficient usage of the resources are important components of the YANOS operational strategy. Refinery’s ecological program, which was implemented in 2017-2020, ranked first in the nomination for “Best Regional Ecological Development Project” of All-Russia “Reliable Partner - Ecology” Competition II. Upon results of 2020, Slavneft-YANOS also won All-Russia Competition XVI – “Environment Protection Leader in Russia”. The Refinery was awarded the certificate in the nomination for “Environment Management and Wastes Control in the Refining Industry”.
