Abstract:
An apparatus for identifying and quantifying a plurality of components in an effluent stream from an ammoxidation reactor, comprising:an ammoxidation reactor having an outlet connected to an effluent line which contains said effluent stream;a microprocessor; anda Fourier Transform infrared spectrometer connected to said effluent line and having a sample cell through which flows a portion of said effluent stream, an infrared source to emit infrared radiation and pass said infrared radiation through said effluent stream, an infrared detector to detect transmitted infrared radiation at selected infrared wavelengths and to generate absorbance data due to absorbance of said infrared radiation by said components, wherein each of said components absorbs infrared radiation at one or more of said infrared wavelengths, and an output apparatus to provide said absorbance data to said microprocessor;wherein said microprocessor is programmed to identify and quantify each of said plurality of components based upon said absorbance data and calibration data, said calibration data being obtained from recovery run analysis and calibration analysis in said sample cell;wherein said effluent stream comprises of acrylonitrile, acetonitrile, propylene, ammonia, hydrogen cyanide, carbon monoxide, carbon dioxide, water, acrolein and acrylic acid as said plurality of components.
