ABSTRACT:
The present invention provides a method for inhibiting fouling deposits in refinery processing equipment caused by the heat treatment of hydrocarbon feedstocks. The deposits are inhibited by adding to the feedstock an effective amount of an iron sulfide dispersant prepared in accordance with this invention. The dispersants comprise polyimides which are prepared by reacting fatty amines with maleic anhydride/alpha-olefin copolymers.
