Abstract
The present invention provides a method for reducing fouling, including particulate-induced fouling, in a hydrocarbon refining process including the steps of providing a crude hydrocarbon for a refining process and adding an antifouling agent containing a polymer base unit and a polyamine group to the crude hydrocarbon. The antifouling agent can be obtained by reacting an epoxidation reagent with a vinyl-terminated polymer, such as polypropylene or poly(ethylene-co-propylene), to form a terminal epoxy group, followed by reacting a polyamine with the epoxy group.
