General Director Gennady Lisovichenko: “Our oil refinery environmental safety was already provided for at the stage of the enterprise engineering”. Read information on the standards applied to processing and the place of environment in the management policy in the “FederalPress” materials.

Antipinsky Oil Refinery is a developing enterprise in the Tyumen Region and is now one of the most powerful in its branch of industry. At the background of the processing volume growth, the way the plant settles environmental problems arouses great interest on the part of state authorities and the region population. Modern production at the Antipinsky Oil Refinery presupposes implementation of new technologies aimed at minimization of oil processing facilities industrial operation impact on the environment.

Tyumen enterprise Antipinsky Oil Refinery CJSC is located in the regional center industrial area, near the settlement of Antipino. The region where the oil refinery construction started eight years ago is one of the major oil processing areas, therefore, especially careful attention is paid here to environmental issues. Antipinsky Oil Refinery modern production demands implementation of innovation solutions in the sphere of environment protection and industrial safety. That is why the enterprise is carrying out complex works for minimization of the harmful impact on the environment.

"Close attention was already paid to environmental safety issues at the stages of the plant engineering and construction commencement. The enterprise performs industrial environmental control aimed at ensuring observation of the nature protection requirements, enterprise General Director Gennady Lisovichenko pointed out, for this purpose, the plant has a special department staffed with personnel highly qualified in the sphere of environment protection. The department employees’ duties include revelation and prevention of environmental regulations violations, planning, and control over nature protection measures, environmental situation monitoring".

The enterprise chemical-and-analytical accredited laboratory and other accredited Tyumen laboratories perform monitoring of the amount of harmful atmospheric emissions from Antipinsky Oil Refinery production activities. All information on the environmental situation on the plant territory and in the sanitary protection zone is analyzed by the Antipinsky Oil Refinery management. The enterprise uses a sealed system in the entire production process chain. Oil is discharged from the process equipment safety valves through a closed system to drainage containers, from where the liquid phase returns to the feedstock depot and the gas phase is sent to the flare system.

In the event of a shutdown for repair, the pipelines are emptied in a similar way. This allows to avoid pollutant emissions into the atmosphere.

The air cooling system is designed to protect underground water. Its efficiency considerably grows in the cold season. Open water reservoirs are protected from waste water discharge with a special water disposal system. At the time of the 2nd commissioning and start up complex construction, pipelines with anticorrosive insulation were laid in the earth at the depth of 1.5 – 4 meters to prevent waste water emergency discharge. All concrete platforms for process equipment are provided with containment fencing and ramps, and the sumps – with valves and hydraulic seals.

Presently, the enterprise is constructing effluent treatment facilities which, in case of oil processing capacity further increase, will ensure treatment of industrial effluent and stormwater to the degree required by the law. After the system start up, the waste water can be used again or disposed into fishery water bodies.

The waste water treatment system will consist of four units. The first unit is designed for the main structures protection from garbage, salvo and emergency pollutant disposals, control of initial waste water irregular delivery to the main treatment facilities. In the second unit, preliminarily clarified waste water is separated from suspended particulate matter and oil products. In the third unit, effluent biological treatment is performed. This development has a number of advantages in comparison with the traditional technology, as it creates a possibility for significant improvement of the treatment quality due to effective removal of suspended and colloid substances, bacteria, viruses, and creates conditions for effective biological destruction of organic compounds and biological organisms due to the membrane ability to hold long molecules for a long time. Besides, in case of the membrane bioreactor use, due to exclusion of some traditional stages of treatment, the areas occupied by treatment facilities are considerably reduced. It should be noted that the entire treatment process is automated, with modern control equipment used, the algorithms for which are developed on the basis of biological treatment control researches. In the final, fourth unit, the waste water final purification is performed. In total, the treatment facilities occupy the area of 10.73 hectares.

When the enterprise oil processing volume reaches 7.5 MIO tons per year, the volume of harmful substances emissions into the atmosphere will increase by 8-10% of the total emissions volume. To ensure the enterprise environmental safety, a program of nature protection measures will be implemented in 2013. Already now, atmospheric air laboratory tests have been performed to check compliance with the requirement to the maximum allowable emission of contaminants from industrial emission sources and on the border of the sanitary protection zone. For the purpose of environmental safety, Antipinsky Oil Refinery will continue to actively interact with the Regional Government, Federal Services of Rosprirodnadzor (Russian Federal Service for Nature Management Supervision) and Rospotrebnadzor (Russian Federal Service for Supervision of Consumer Rights) for the Tyumen Region, and with the Tyumen Administration Environment Committee.
