Abstract: An anti-fouling composition has been developed that provides an advantageous reduction in the fouling of a structural part in a petroleum-refining system including reducing coking reactions and inhibiting deposition of solids in equipment and lines used for crude oil production and processing. The anti-fouling compositions contain a resin comprising an alkyl phenol-aldehyde resin, a polyolefin comprising a polyalkylene ester, polyolefin amide alkeneamine, polyethylene polyamine, polyalkyleneimine, or a combination thereof; and optionally, a polyalkylene imide, an amine-substituted polyalkylene imide, or a combination thereof; and optionally, N,N?-disalicylidene-1,2-propanediamine.

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 ?-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.
