In this article given a comparative economic and environmental calculation of the use of a packed absorption column and an electrochemical reactor designed to purify air of hydrogen sulfide in the processes of ensuring environmental safety from potentially negative impacts of the surrounding technical facilities of the city, accompanied by emissions of hydrogen sulfide generated in sewers and emitted into the air of settlements. A significant advantage of the electrochemical air purification from hydrogen sulfide is shown compared with the absorption method of cleaning in packed columns using an aqueous solution of monoethanolamine as an absorbent. On the basis of practical experimental data, the optimal technological parameters of the process of electrochemical oxidation of hydrogen sulfide (current and voltage values) and the circuit diagram of a flow-through electrochemical reactor are determined.
