Abstract
This article deals with CF4 abatement by electrodeless atmospheric pressure microwave plasma torch. The plasma abatement device is attached to the vacuum pump, which discharges the nitrogen gas with contaminants. The abatement was carried out using oxygen and air as an additive gases. The destruction and removal efficiency (DRE) of more than 98% was achieved for tetrafluoromethane(CF4). The detailed characterization of CF4 abatement using Fourier transform infrared (FT-IR) and quadrupole mass spectrometer (QMS) showed the major PFC by-products.
