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 treating a powder, includes: dry mixing the powder with an effective amount of a treating additive to distribute a layer of the treating additive on a surface of a particle of the powder, a primary particle size of the treating additive being smaller than an average particle size of the powder. An associated treated powder is also described.
