Abstract:
The present application 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 an additive selected from: (I), (II) and (III),wherein R 1 , R 2 , R 3 , and R 4 are independently selected from a branched or straight- chained C 5 -C 8O alkyl group, and M 1 , M 2 , and M 3 are independently selected from Ca, Mg and Na.

Abstract:
The present application 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 a polyalkyl succinic acid derivative additive. The additive can be complexed with a boronating agent, such as boric acid, to yield a boron-containing polyalkyl succinic acid derivative.
