ABSTRACT:
Multifunctional process antifoulant compositions and methods are disclosed. The compositions comprise (1) a polyalkenylthiophosphonic acid or ester thereof, and at least one additional antifouling component selected from the groups (2), (3) and (4) wherein (2) is an effective antioxidant compound adapted to inhibit oxygen based polymerization of said hydrocarbon or petrochemical, (3) is a corrosion inhibiting compound, and (4) is a metal deactivator. The process comprises adding from about 0.5-10,000 parts of the combination of (1) and additional antifoulant component(s) to the particular petrochemical or hydrocarbon for which multifunctional antifouling protection is desired.
