Increasing Gas Removal Efficiency in the Work Area of Electrolyzers with Prebaked Anodes with Current Strength of over 300 kA

Abstract

There are presented the results of studies on determining the minimum amount of gas suction ensuring the efficiency of the shelter at a level exceeding 98 % at steady state operation of the electrolyzer and the amount that ensures the shelter efficiency above 90 % when replacing of the anodes. Introduction of the results obtained in industrial scale is shown to reduce power requirement of gas treatment plants by 10…15 %, lamppost emissions – by 20…25 %. Equipping of electrolyzer's work space by a shelter in the form of separation baffler would reduce lamppost emissions of hydrogen fluoride to 1.08…1.1 times, carbon dioxide – to 1.2…1.22 times, carbon monoxide – to 1.2…1.3 times.
