Effect of anode coating material on the electrolytic oxidation of hydrogen sulfide in gas cleaning systems

Summary

Possible removal of malodorous substances from ventilation systems at the wastewater disposal facilities by adsorption is shown, where water containing an oxidizer – sodium hypochlorite – is used as an absorbent. For further development of this method, the results of experimental studies of the effect of the anodic coating composition on the specific energy consumption for the production of electrolytic sodium hypochlorite are presented. The results of experimental studies of the effect of the anode coating composition during the oxidizer reduction in the process of removing hydrogen sulfide from gas-air emissions in a counter-current absorber with circulation of the absorption solution showed that the nature of the anode coating significantly affected the concentration of sodium hypochlorite generated during the electrolysis of the chloride-containing solution, and also on the energy characteristics of gas cleaning.
