In this work, a transferred plasma system was realized to vitrify mixed wastes, taking advantage of its high power density, enthalpy and chemical reactivity as well as its rapid quenching and high operation temperatures. To characterize the plasma discharge, a temperature diagnostic is realized by means of optical emission spectroscopy (OES). To typify the morphological structure of the wastes samples~ scan- ning electron microscopy (SEM), and X-ray diffraction (XRD) techniques were applied before and after the plasma treatment.展开更多

Chemical radicals produced with this technology can remove several pollutants at atmospheric pressure in a very short period of time simultaneously. Both theoretical and experimental study on SO2 and NOx removal, by a dielectric barrier discharge (DBD) with corona effect, is presented.展开更多
