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.
