PROCESS USING POLYPROPYLENE OR POLY (ETHYLENE CO PROPYLENE) SUCCINIMIDE AS ANTIFOULING ADDITIVE IN PETROLEUM REFINERY PROCESSES

摘要

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; adding at least one polyalkyl succinic anhydride derivative additive disclosed herein. The additive can be complexed with a boronating agent, such as boric acid, to yield a boron-containing polyalkyl succinic anhydride derivative.
