POLYALKYLENE CARBOXYLIC ACID POLYAMINE ADDITIVES FOR FOULING MITIGATION IN HYDROCARBON REFINING PROCESSES

摘要

Methods and systems for reducing fouling, including particuiate-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 are provided. The antifouling agent can be obtained by convertmg a vinyl terminated polymer, such as polypropylene or poiy(ethylene- co-propylene), to a terminal acyl containing functional group, followed by reacting the terminal acyl containing functional group with a polyamine compound.
