Parametric investigation and RSM optimization of DBD plasma methods (direct & indirect) for H₂S conversion in the air.

ABSTRACT: Hydrogen sulfide (H₂S) is known as a harmful pollutant for the environment and human health, and its emission control is a high priority. Non-thermal plasma is an effective technology in this field. In this study, for the first time, the performance of direct and indirect H₂S plasma conversion methods was compared, optimized, and modeled with the CCD method. H₂S was diluted in zero air, and the study investigated the effect of discharge power, relative humidity, total flow rate, initial H₂S concentration, and their interactions. ANOVA results showed that the models for H₂S conversion efficiency and energy yield were significant and efficient. The direct method achieved a maximum conversion efficiency of 56 % and energy yield of 3.43 g/
