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 ().

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.

Reduced fouling of hydrocarbon oil

Described herein are systems and methods for evaluating and mitigating the fouling potential of a given crude oil. The system and methods enable the refiner to rapidly and readily identify the particular mechanisms by which a crude oil may foul, and to select the optimal chemical treatment and/or crude blend to mitigate fouling potential.

System and method to mitigate fouling during a hydrocarbon refining process

Antifoulant compositions and methods are used for inhibiting fouling on structural parts of a system exposed to a fluid hydrocarbon or petrochemical stream. The antifoulant compositions may comprise at least one polyalkylene anhydride ester ('PAAE') dispersant. Other antifoulant compositions may comprise an alkylphenol sulfide ('APS').
