RECONSTRUCTION OF GAS CLEANING PLANTS OF LURGI-552 KILNS, PJSC «SEVGOK»
Reduction of harmful emissions into atmosphere is one of the most urgent issues of modern production.
Experienced specialists of M TECHNOLOGY work on implementation of innovative technologies and improvement of process gas cleaning methods at metallurgical and other enterprises.
Thus, in 2017, the company developed a project for reconstruction of dedusting gas cleaning system for the Lurgi-552-B kiln that to complete complex modernization of the gas cleaning, which had began in 2011 and included replacement of process gas systems of the drying and heating areas.
These comprehensive measures reduced gross emissions of pollutants into atmosphere by 447 tons/year.
After successful implementation of the projects it was decided to continue modernization of the gas cleaning plants for the kilns to ensure the targeted purification degree of waste-gases and to reach the value of less than 50 mg/nm3.
Thus, in 2018-2019, M TECHNOLOGY developed respective project documentation.
Key work moments:
Construction and installation works were carried out without interrupting technological process and reducing production. For these purposes the company experts installed a bypass duct and an additional electric filter with a smoke exhauster to ensure purification of process gases for the reconstruction period.
An additional electrostatic precipitator will be used in the future to clean the process gases of the Lurgi-552-A kiln after its reconstruction and to increase production of pellets by 10%.
In the absence of alternative space, new electrostatic precipitators were located in the places of the existing ones.
Modern electric filters, manufactured by «ZVVZ» company, used in the project, ensured the targeted dust content in gas emissions – less than 50 mg/nm3.
Dust counters have been installed at the exit of each electrostatic precipitator, which ensured control of the operation parameters of the gas cleaning system, as well as decrease of power consumption when necessary purification values of waste gases have been reached.
During reconstruction of the aspiration electrostatic precipitator the filter casing and supporting part were preserved, which significantly reduced capital costs and shortened the time of construction and installation works.
Thus, we managed to reduce gross emissions into atmosphere by 447 tons/year.
The work performed is an excellent example of how modern technologies and creative engineering solutions can contribute to fighting against air pollution.
