"Reconstruction of the heat recovery and cleaning system of the regenerator gases at the Catalytic Cracking Unit"
"In 2014, AD "LUKOIL Neftekhim Burgas" implemented a Project for the reconstruction of the Heat Recovery and Cleaning System of the P-202 regenerator gases from the catalytic dust at the Catalytic Cracking Unit (FCCU) with a capacity of 2 million tons/year.
During the implementation of the Project, the Waste Heat Boiler was changed on new one with boiler water treatment station, the new gas cleaning system (Filter) from catalyst dust with a system for continuous monitoring of harmful emissions was installed, and the closed system for collecting and transporting captured catalyst dust from the boiler and filter to the separate silo for subsequent unloading was installed.
The scope of the contractor's work of the executed Project included the development of project documentation, equipment delivery, installation, supervision and commissioning.
According to the objective control data of the continuous emission monitoring system, the content of catalyst dust in the waste gases does not exceed 10 mg/Nm3.
After two years of industrial operation, the installed System maintains sustainable and reliable performance parameters for the steam capacity of the waste heat boiler, the efficiency of cleaning the regenerator gases from catalyst dust, and ensures compliance with the requirements of European standards (EU 201/75/EC).
The work was completed in the required time, efficiently and in accordance with the requirements specification."

Reduction of catalyst dust emissions at LUKOIL Neftohim Burgas AD
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 introduction of this technology will enable LUKOIL Neftohim Burgas to ensure the production's compliance with the new European regulations planned for enforcement in 2020.
