The emerging environmental problems of the cells with the Soderberg`s anode, associated with the lack of a vacuum alignment system in the subcaseous gas outlet network and an effective technological device for high-temperature oxidation of anode gases are considered. In order to increase the efficiency of high-temperature oxidation of harmful components of the anode gas, a compact burner with internal thermal insulation has been proposed, which is installed on the longitudinal side of the anode, which makes it possible to reduce CO emissions by 1.5 times. Considering the insufficient efficiency of the wet gas cleaning stage for sulfur dioxide, it is recommended to replace it with a dry adsorption gas cleaning using nepheline sludge as an adsorbent, which provides for sulfur dioxide trapping by 95–100 %.
