In line with its environmental policy LUKOIL Neftohim Burgas invests resources in the best available modern technologies, which allow reducing the level of environmental pollution at refinery sites.
In order to provide the environmental safety in LUKOIL Neftohim Burgas, the best available techniques are applied enabling the processing of hydrogen sulfide and water, reduction of hazardous emissions and safe processing of environmental residue.
LUKOIL Neftohim Burgas is continuously retrofitting the existing and constructs new facilities to improve the environment of the region of the company's operation: a new Sulphur Recovery Unit — 4, furnace flue gases treatment systems, new waste heat boiler and filtration system.
Sulphur Recovery Unit — 4 is designed to recover Hydrogen sulphide obtained from thermocatalytic processes of oil fractions updating.
The facility is used for both the new Heavy Residue Processing Complex units and the operating units of the refinery.
The unit's output capacity is 300 tons of granulated sulphur per day, and the sulphur extraction level is no lower than 99,8%.
The new Unit creates spare capacities for hydrogen sulfide processing.
A new waste heat boiler П-401 was built at the Catalytic Cracking unit, and a DAHLMANN filtration system was also installed.
The system is a new generation technology in oil refining and this is one of its first applications within the European Union.
In contrast to the treatment facilities widely used up this moment, allowing to achieve catalyst dust emissions reduction to 20—40 mg/nm3, the new process guarantees 10 mg/nm3, and the analysis done during the test of the installed filter demonstrated results of 0,3 mg/nm3.
The implementation of this project enabled the achievement of major ecological effects:Substantial improvement of Catalytic Cracking unit's energy efficiency;
Improved heat energy savings amounting to 48 th. MWt per year;
Reduced emissions of greenhouse gases — СО2 to 45 kt/year (cca. 5% of total СО2 emissions of the refinery);
Reduced catalyst dust emissions to 38 tons/year compared to the legally acceptable quantities.
The enterprise has built flue gases treatment systems on furnaces F-101 and F-2101 of Hamon. These are equipped with DeNOx units for nitrogen oxides removal, electric filters, DeSOx units for sulphur oxides removal, and are in full conformity with current requirements of energy efficiency, reagent use and operation performance.
The treatment systems made it possible to reduce the annual emissions of the two furnaces by cca. 210 tons for SOx, 90 tons for NOx and 70 tons for dust particles.
LUKOIL Neftohim Burgas is actively working on the implementation of the Program for remedy of past environmental damages. Within the framework of this Program the following projects are ongoing:
Recultivation of polluted soils on the main production site and the port terminal of LUKOIL Neftohim Burgas. 93 th.m3 of waste have been neutrilised, and by In-situ–bioremediation method and Еx-situ–bioremediation of 75 th.m3 of oil-contaminated soils have been recultivated. The total cost of works amounts to 5,1 mln BGN;
Closing and recultivation of industrial waste warehouse with cost of 3,6 mln BGN;
Closing and recultivation of first oxidising lake — first phase is in progress, its cost amount to 12,7 mln BGN;
Construction of underground water monitoring system the cost of which is 250 th. BGN.
Pursuant to the requirements of p. 7.4.3 “External exchange of information” of ISO 14001 international standard, “LUKOIL Neftohim Burgas” AD decided to disclose publicly the information about its essential environmental aspects.
