ОАО Mozyr Refinery

The Mozyr Refinery was launched in 1975. The Enterprise is located in the Gomel region, in the Republic of Belarus. The Refinery manufactures high-quality motor gasoline, Euro-5 eco-friendly diesel fuel, fuel oil, bitumen, domestic gas, lighting kerosene, and vacuum gasoil.
Mozyr Refinery’s products are characterized by such consumer properties, as the low content of sulfur compounds in diesel fuel, a high calorific value of residual fuel and no tetraethyl lead in motor gasoline. The Quality Management System certified under the ISO 9001:200 standard is in force in the Refinery. The Enterprise was awarded the Republic of Belarus Government Prize for Quality in 2002, 2005, 2010 and 2015.
SLAVNEFT and the Government of the Republic of Belarus are key shareholders of the Mozyr Refinery. SLAVNEFT’s share in the Mozyr Refinery authorized capital makes 42.58%. The Byelorussian Government owns 42.76% of the Refinery’s shares. 12.25% of the shares is held by OOO MNPZ Plus (RB), which is fully controlled by the State. Individuals hold 2.41% of the Refinery’s shares.  
Since 1996, the Mozyr Refinery has been upgrading the operational facilities on a step-by-step basis in order to increase the crude oil processing depth and manufacture products complaint with the global quality standards. Over the past period, LK-6U, one of the two key processing complexes, was revamped; the Tar Visbreaking Unit, Vacuum Gasoil Hydroconversion Unit, Hydrogen Fluoride Alkylation Unit, Catalytic Cracker, Gasoline Hydrodesulfurisation Unit, Benzene Production Plant and a score of other facilities were constructed.
Due to implementation of the development program, the Mozyr Refinery commissioned the Diesel Fuel Hydrotreatment Unit and MEA Regeneration Block of the Sulfur Production Unit, launched the Hydrogen Production Unit, Pentane-Hexane Fraction Isomerization Unit and Residual Oil Vacuum Distillation Unit in 2011-2015. Besides, the on-spot loading rack, diesel fuel tank farm and loading facilities, and methanol tank farm were constructed; the automated system of control over emissions from the H-3001 process heater of the Combined Alkylation Unit was introduced. The Enterprise managed to increase the hydrocarbons refining volume, proceed with manufacturing of Euro-5 motor gasolines and significantly mitigate the environmental risks due to upgrading of the operational facilities and enhancement of the technological processes.  
Now the Mozyr Refinery is implementing the program of development until 2020 focused on further increase in the crude oil processing depth and enhancement of the products quality. In 2016, the Enterprise commissioned the Combined Plant for Production of Gasoline High-Octane Components, Sulfur Production Unit and the C4 Butane Fraction Adsorption Treatment Unit. In 2017, the Refinery commenced fulfilling the investment project on construction of the Vacuum Gasoil Hydrocracking Complex, which would increase the quantity of light oil products manufactured.  
In 2018, the Refinery became the first in Belorussia that mastered production of the new motor fuel type with octane number 100, i.e. 100 RON-K5-Euro, due to upgrading and introduction of the advanced technologies. The Enterprise is actively implementing the largest project in its history, i.e. construction of the Black Oil Hydrocracking (H-Oil) Plant. The Plant will include a Hydrogen Production Unit, Sulfur Production Unit and 21 auxiliary facilities. This project execution will allow the Mozyr Refinery increasing the oil processing depth up to 90% and incrementing the production of diesel fuel with the sulfur content of 10 ppm at most by more than 800 kilotons.
Construction of the Continuous Catalytic Reformer and Vacuum Gasoil Hydrocracking Complex is considered as the promising projects for development of the Mozyr Refinery.
