“…Among others, the pollutants successfully treated with plasma are acid gases such as NO x , [1][2][3][4][5][6][7] SO x , [6][7][8][9][10] and greenhouse gases such as CO x , [11,12]. Despite successful control in a number of industries, the emitted amounts of volatile organic compounds (VOCs) are still substantial.…”

Methanol and dimethyl sulfide are volatile organic compound (VOC) air pollutants that are subject of severe environmental regulations due to their toxicity, environmental persistence and odor. Traditional technologies are often inefficient for their removal, especially in the case of the dilute industrial streams. Non-thermal plasma methods, typically characterized by high removal efficiency, energy yields and good economy, offer possible alternative solutions. The present research employs pulsed corona discharge known for its high selectivity and low energy costs of emission control. This paper provides experimental (Part I) and in a later issue numerical (Part II) data on removal of methanol and dimethyl sulfide from dry and humid air streams. The removal efficiency and the specific energy input are evaluated along with the energy costs required for the removal process. Particular attention is given to the formation of unwanted byproducts such as NO x , CO, and SO 2 .

“…Recently, MASUDA et al [12] demonstrated that the rise time of the current pulses is of fundamental importance in generating free radicals without increasing the temperature of positive ions. WANG et al [13] have proved experimentally that the pulsed corona discharge, of the same peak voltage, offers better DeNO, results for positive polarity than negative one. A small admixture of NH3 [7] or CH4 [7, 181 allowed to decrease the N20 content in the treated gases.…”

The back-corona discharge has been successfully applied as a plasma source for decomposition of NO2 in the oxygen-free gas mixture of Nz: NOz. The paper reports a first attempt to use back-corona discharge for noxious gas conversion. The preliminary results of laboratory experiments in a needle-to-plate reactor show that the De-NO, processes in back-corona discharge are similar to the dc streamer corona discharges generated in the same geometry. Both types of discharges convert NO:! to nitrogen, oxygen and also to NzO and NO.However, back-corona discharge produces less NO, and is more efficient energetically in NO, decomposition than the dc streamer corona discharge.

Various active species can be formed by a pulsed discharge in water, and these active species may play an important role in killing bacteria and degrading organic compounds. In recent years, interest in the formation of OH, O 3 and H 2 O 2 has grown enormously. The O is also a very powerful oxidant, but little research has been done on the oxygen radical. In this paper, production of atomic oxygen by the pulsed streamer corona discharge in water has been identified. The effects of applied voltage polarity, peak voltage, oxygen and inert gases bubbling on radical formation have been investigated.Keywords: oxygen radical; pulsed discharge in water; peak voltage; gas bubbling.Reference to this paper should be made as follows: Sun, B., Zhang, L. and Sato, M. (2008) 'Characteristics of atomic oxygen produced by a pulsed streamer corona discharge', Int.
