ABSTRACT:
A method for controlling the formation of fouling deposits in a liquid hydrocarbonaceous medium, wherein in the absence of such fouling inhibition, fouling deposits would normally be formed within said medium is disclosed. The method comprises adding to said medium an antifoulant composition comprising a basic antifouling compound, component (1), selected from the group consisting of alkyl phosphonate phenate sulfide, alkaline earth alkyl phosphonate phenate sulfide, an amine neutralized alkyl phsophonate phenate sulfide, or mixtures thereof, and at least one additional antifouling compound selected from components (2), (3) and (4) wherein component (2) is an effective antioxidant compound adapted to inhibit oxygen based polymerization of said hydrocarbon or petrochemical, component (3) is a corrosion inhibiting compound, and component (4) is a metal deactivator. The process comprises adding from about 0.5 to about 10,000 parts of the combination of (1) and additional antifoulant component(s) to the particular hydrocarbonaceous medium for which multifunctional antifouling protection is desired.
