The efforts on regulation and reduction of ozone-depleting substances (ODS) have been strengthened in the world. In this study, we study a decomposition of refrigerant gas using a 2.45GHz microwave plasma torch that has several advantages of electrodeless discharge, thermal and large volume plasma. In addition, the experiment was designed to reverse vortex reactor in order to increase the processing capacity. The experiments of decomposition have been performed with respect to CCl2F2(CFC-12) by varying plasma power and discharge gas of nitrogen and air, and CFC-12 flow rate. Detailed experiments were conducted on the abatement of R-12 in terms of destruction and removal efficiency (DRE) using Fourier Transform Infrared (FT-IR). To study a solidification of refrigerant by-product gas and stainless steel, we were analyzed synthetic materials in the plasma reactor with the scanning electron microscopy coupled with energy dispersive X-ray (SEM/EDX) and X-ray diffraction (XRD) spectroscopy. |
