ABSTRACT:
An on-line method of monitoring and controlling a chemical process is based on measuring the concentration of process reactants and products using spectrometric technology. The spectral data is analyzed using a modified chi-squared processing method to determine the unknown concentration of reactants and products in test samples withdrawn from the process. This method avoids the need for the spectral data to conform to Beer's Law and the best spectral range is determined automatically. The physical parameters of the process are monitored and altered based on this determination as required to optimize the process.
