Abstract
Disclosed herein are antifouling compositions including a combination of one or more dispersant polymers and one or more inhibitors, the one or more dispersant polymers including the polymerized residues of one or more α-olefins and maleic anhydride, further wherein the maleic anhydride residues are reacted with a primary amine; and the one or more inhibitors including a functionalized p-phenylene diamine. Concentrates of the antifouling compositions in solvents are stable and pourable at temperatures of 0° C. to −40° C. The antifouling compositions are added to a petroleum product to form a treated petroleum product, wherein fouling by the treated petroleum product is reduced and a stable dispersion is formed over a wide range of processing conditions.
