“…22 The addition of O 2 further enhances the H 2 S removal rates via similar reaction pathways as for the Claus process. 23 The presence of oxygen, however, might well have a negative impact like the production of SO 2 and SO 3 for thermal 24,25 and non-thermal plasmas [26][27][28] as well as for combinations of plasma and photolysis. 29 Thus, some groups even use the ozone downstream of a plasma discharge.…”

The efficient removal of hydrogen sulfide, H2S, from streams of H2S in air via a dielectric barrier discharge (DBD) plasma has been investigated using a quadrupole mass spectrometer. A suitable plasma device with a reservoir for storing sorbent powder of various kinds within the plasma region was constructed. Plasma treatments of gas streams with high concentrations of hydrogen sulfide in air yielded a removal of more than 98% of the initial hydrogen sulfide and a deposition of sulfur at the surface of the dielectric, while small amounts of sulfur dioxide were generated. The presence of calcium carbonate within the plasma region of the DBD device resulted in the removal of over 99% of the initial hydrogen sulfide content and the removal of 98% of the initial sulfur dioxide impurities from the gas mixture.

“…Previous research using a non-thermal dielectric barrier discharge plasma reactor filled with ceramic Raschig rings exhibited good hydrogen sulfide removal performance (Liang et al 2011). Another bench scale system integrated with a NTP and biotrickling filtration unit was investigated for the treatment of gases containing dimethyl sulfide (Wei et al 2013).…”

Waste gases containing sulfur compounds, such as hydrogen sulfide, sulfur dioxide, thioethers, and mercaptan, produced and emitted from industrial processes, wastewater treatment, and landfill waste may cause undesirable issues in adjacent areas and contribute to atmospheric pollution. Their control has been an area of concern and research for many years. As alternative to conventional physicochemical air pollution control technologies, biological treatment processes which can transform sulfur compounds to harmless products by microbial activity, have gained in popularity due to their efficiency, cost-effectiveness and environmental acceptability. This paper provides an overview of the current biological techniques used for the treatment of air streams contaminated with sulfur compounds as well as the advances made in the past year. The discussion focuses on bioreactor configuration and design, mechanism of operation, insights into the overall biological treatment process, and the characterization of the microbial species present in bioreactors, their populations and their interactions with the environment. Some bioreactor case studies are also introduced. Finally, the perspectives on future research and development needs in this research area were also highlighted.

“…I N RECENT years, plasma researchers have studied the reforming characteristics of all types of plasma [1]- [9], both thermal [2], [3], [5] and nonthermal [1], [4], [6], [10], in a fuel conversion system [5], [11] with many types of fuels [4], [7], [10]- [12]. Research has been largely focused on determining the plasma discharge for fuel reforming and improving the energy efficiency of a plasma system.…”

A new kind of gliding-arc reactor was designed for this study. A shape-memory-alloy electrode controls the discharge arc movement at the start of the discharge stage, while the root of the arc shifts to the ground electrode under normal operation. Experimental results for electrical parameters (voltage and current) in air were analyzed. When the power is adjusted from 50 to 70 W, the discharge waveform is close to sinusoidal at the condition of high power supply. The voltage-versus-current relationship was studied for the Reynolds number (Re number) ranging from 1174 to 2609, current ranging from 20 to 50 mA, and electrode gaps ranging from 11 to 24 mm. There is a linear relationship between root mean square (rms) voltage and the electrode gaps and an inverse linear relationship between rms voltage and rms current.
