Title: POLYMERIC DISPERSANTS FOR PETROLEUM PROCESS STREAMS
Abstract:
Disclosed herein are methods and compositions for reducing fouling by natural and synthetic foulants that tend to precipitate during petroleum collecting, processing, transporting, and storing. The method includes applying one or more antifouling polymers 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. The one or more antifouling polymers include the polymerized residues of one or more α-olefins and maleic anhydride, further wherein the maleic anhydride residues are reacted with a primary amine. Concentrates of the antifouling polymers in solvents are stable and pourable at temperatures of 0 °C to -40 °C.
