Abstract: A method (200) for desulfurization of a flue gas in a desulfurization unit of an industrial plant, includes receiving (202) a plurality of baseline parameters corresponding to the desulfurization unit of the industrial plant. The method further includes measuring (204), using a stack sensor, an emission value of sulfur oxides in the flue gas. The method also includes estimating (208), using a controller, a desirable value of a slurry parameter for desulfurization of the flue gas based on the measured emission value of the sulfur oxides. The method further includes determining (208), using the controller, at least one desulfurization parameter based on the desirable value of the slurry parameter. The method also includes controlling (210), using the controller, operation of the desulfurization unit based on the at least one desulfurization parameter to modify consumption of at least one of a slurry and an auxiliary power in the industrial plant.

Abstract: A method includes receiving a gas mixture at a first pressure including at least a primary gas and a secondary gas and changing a pressure of the received gas mixture from the first pressure to a second pressure. Further, the method includes determining a spectra of the gas mixture at the second pressure, wherein at least the first spectral line of the primary gas is spectrally distinguished from at least the second spectral line of the secondary gas, identifying a peak wavelength associated with the spectrally distinguished first spectral line of the primary gas based on at least two wavelengths of the secondary gas corresponding to at least two peak amplitudes in the spectra of the gas mixture, and determining a concentration of the primary gas based on the identified peak wavelength associated with the spectrally distinguished first spectral line of the primary gas.

Abstract: A system is presented. The system includes an electromagnetic radiation source configured to generate a mode matched electromagnetic radiation that irradiates a gas mixture filled in a gas compartment at a determined pressure ‘P’ bars, an intensity enhancement mechanism that internally reflects the mode-matched electromagnetic radiation a plurality of times to achieve an effective intensity ‘E’, of reflected electromagnetic radiation in a region of interest, that is ‘N’ times an intensity of the mode-matched electromagnetic radiation, and a detection subsystem that analyses the gas-mixture based upon Raman Scattered photons emitted from the region of interest, wherein a product of the ‘P’ and the ‘N’ is at least 30.
