Abstract
A method for monitoring and controlling unwanted polymer byproduct generated in a monomer production, storage, or handling process, for example polystyrene in a styrene production process, is described. The method comprises receiving a sample () taken during a monomer production process by a Fourier-Transform infrared spectrometer (), performing an infrared spectroscopy analysis on the sample to generate spectral data () by the Fourier-Transform infrared spectrometer, and determining a percentage () of at least one polymer in the sample by mathematical correlative processing of the spectral data by a computing device ().
