Unsteady Method of Production of Sulfuric Acid from Waste Metallurgical Gases.
Abstract
At the Krasnoural'sk Copper Smelting Plant a sulfur dioxide oxidation reactor capable of processing 40,000 m**3/hr of converter gases has been put into operation. The reactor operates according to a new principle consisting in periodic alternations of the direction of injection of a low-temperature gas mixture into a stationary catalyst bed, thus making it possible to reduce the metal volume of the contact unit sixfold and to eliminate heat exchangers and reheating of the gas mixture.
The main problem of the development of nonferrous metallurgy in Russia is production ecology. This problem is related to the
necessity of the production of various wastes and effluents, namely, gaseous (including aerosols), solid, and liquid wastes,
and the development and implementation of new technologies to prevent these wastes and effluents. Modern technologies developed
at the FGUP Gintsvetmet Institute in the field of the deactivation of toxic wastes and new technologies for the processing
of ores, concentrates, and byproducts containing nonferrous metals are presented.
