Abstract: plasma processes are among the emerging technologies for volatile organic compounds (VOCs)
sbatoment. Both thermal plasmas and non-equil[brimn plasmas (cold plasmas) are being
developed for VOCs clesnup. Particularly, pulsed corona discharges offer several edvantages
over conventional VOCs abatement tochniqvee, To optimize the existing technology and to
developit further, there is need to understand the mechanlsms involved in plasma chemical
reacticms, Furthermore, it is strongly desirable to be able to predict the behavior of new
VOCs in non-equillbrlum plasma enviromuent from the data known for a few representative
oompounds, Pulsed corona discharge technique is introduced here with dtafion of refevant
literature, Fundamental principfes,useful for predicting the VOCs’ decomposition behavior,
have been worked out from the published literature. Latest developments in the area,
targeted to minimize the enersy losses, improve the VOCs destruction efficiency and reduce
the generation of unwanted organic and inorganic by-products, are presented.
