Abstract: Antifoulant compositions and methods are used for inhibiting fouling on structural parts of a system exposed to a fluid hydrocarbon or petrochemical stream. Polyamine antifoulants are added to such systems. The polyamine antifoulants may be conjointly used with dispersants and/or fatty acids. The fatty acids have been found to reduce thermal degradation of the polyamine antifoulants.

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 (115) taken during a monomer production process by a Fourier-Transform infrared spectrometer (120), performing an infrared spectroscopy analysis on the sample to generate spectral data (122) by the Fourier-Transform infrared spectrometer, and determining a percentage (119) of at least one polymer in the sample by mathematical correlative processing of the spectral data by a computing device (110).
