DEVELOPMENT OF A SCHEME FOR A CHAIN OF DEVISES FOR GAS EMISSIONS CLEANING FROM METALLURGICAL PLANTS USING AN APPARATUS WITH A VIBROBOILING BED OF FERROMANGANESE NODULES

Abstract

In the analysis of the components of gas emissions from metallurgical industries, it is generally accepted that sulphur dioxide is the most harmful to the surrounding ecosystem, and its capture is a pressing problem. The aim of the development is to design a circuit diagram of devices chain for reducing the emissions of toxic gases from metallurgical plants using new technological solutions on the example of purification of roasting gases from sulphur dioxide in the production of molybdenum. The scheme includes an adsorber developed with a vibrating adsorbent layer, which is recommended for ferromanganese nodules (FMN), which have advantages over other adsorbents, including activated carbon. In the case of a spent adsorbent treatment system, elemental sulfur can be produced in the circuit, and FMN should then be considered as manganese concentrates and feedstock for the complex recovery of the associated elements: copper, nickel, cobalt. The line can be used in smelters firing sulphide ores, as in other industries emitting gases with sulphur dioxide as well.
