Modernization of Systems Used for Process- and Ventilation-Gas Cleaning at the Ridder Metallurgical Complex of the Company Kaztsink

The Ridder Zinc Plant is a large nonferrous metallurgy complex in the Republic of Kazakhstan. The process gases from the different conversions at the factory undergo fine-cleaning in bag filters and electrostatic precipitators. Recommendations are given on improving the performance of the dust-removal, ventilation, and aspiration systems of the factory's shops and several alternatives are proposed for modernizing the designs of the bag filters and precipitators. Implementation of the recommendations will improve air quality at the work stations and reduce the amount of metal lost in the hazardous emissions that are released into the atmosphere. The results can be used to design ventilation and aspiration systems at other plants in the nonferrous metallurgy industry.
