Modernization of the Exhaust Gas Evacuation System of Electrolysis Production of JSC "RUSAL Bratsk"

Abstract

It has been shown that in the electrolysis production of RUSAL Bratsk OJSC in recent years significant technological changes have occurred: the electrolyzers are switched to “the dry” anode technology, the current strength is increased, and the chemical composition of the petroleum coke used in the production of the anode mass has changed. The above facts led to a change in the chemical and physical composition of the exhaust gas, as well as to a change in the volume of their formation, which forced the modernization of the evacuation system of the exhaust electrolysis gases by changing the design of the burner devices.
