  • Spectroscopic analysis and control
    Patent number: 9625373
    Abstract: Apparatus for spectroscopic analysis which includes a tunable diode laser spectrometer having a digital output signal and a digital computer for receiving the digital output signal from the spectrometer, the digital computer programmed to process the digital output signal using a multivariate regression algorithm. In addition, a spectroscopic method of analysis using such apparatus. Finally, a method for controlling an ethylene cracker hydrogenator.

  • Excess Air Control For Cracker Furnace Burners
    Publication number: 20110062056
    Abstract: A method for control of the air/fuel ratio of the burner(s) (excess air) of a thermal cracker which includes three steps. The first step is to direct a wavelength modulated beam of near infrared light from a tunable diode laser through combustion gas from the burner to a near infrared light detector to generate a detector signal. The second step is to analyze the detector signal for spectroscopic absorption at wavelengths characteristic for an analyte selected from the group consisting of oxygen, carbon monoxide and nitrogen oxide to determine the concentration of the analyte in the combustion gas. The third step is to adjust the air/fuel ratio of the burner(s) (excess air) in response to the concentration of the analyte of the second step.
