Abstract: The present invention relates to a method for treating fluoro-containing and silicon-containing gas. The method comprises treating the gas with thermal-treating, particles-treating, catalyst-treating, and acid-removing sequentially to remove perfluorocompounds. The invention achieves results of reducing the working temperature, increasing the lifetime of the catalyst, reducing the operating cost of the system, and increasing the applications of the catalyst in the aspect of fluoride-containing gas, silicon-containing gas and particles containing gas treatment by sequential treating.

Abstract: The invention provides a method for decomposing sulfur-fluorine-containing compound and apparatus thereof. Sulfur-fluorine-containing compound is decomposed in two steps, comprising contacting the compound with a first catalyst such as a monometallic catalyst and a second catalyst such as a bimetallic catalyst, and at a low reaction temperature to produce resulting compounds capable of water-solubility. Then, the resulting compounds, namely sulfur- or fluorine-containing compounds, are removed by washing.

Abstract: A gas analysis system. The system includes a Fourier transform infrared (FTIR) spectrometer, a signal transformation module, an unknown chemical analysis module, a calibration model determination module, and a gas concentration calculation module. The signal transformation module receives electronic signals corresponding respectively to background and sample interferograms corresponding to a sample gas from the FTIR spectrometer for further calculation to obtain an absorption spectrum of the sample gas. The unknown chemical analysis module qualitatively analyzes the absorption spectrum of the sample gas to determine the chemical species in the sample gas. The calibration model determination module decides a calibration model. The gas concentration calculation module calculates the gas concentration of each chemical species according to the absorption spectrum, the calibration model and a standard spectrum of the chemical species.
