ABSTRACT:
The present invention is a method of preventing fouling and coke formation on the high temperature sections of hydrocarbon processing equipment which comes into contact with a hydrocarbon fluid. The method comprises adding to a carrier prior to the carrier coming into contact with the high temperature sections of such equipment, an effective amount of an antifoulant in its vapor phase selected from the group consisting of tri-tertiary-butylphenol phosphate esters and compounds having the formula I: ##STR1## wherein Q is Z, or R with the proviso that two occurrences of Q are Z, R is hydrogen, or a straight or branched alkyl group having from 1 to 7 carbon atoms, and only one or two occurrences of R may be alkyl. Z is represented by the formula II: ##STR2## wherein R.sub.2 and R.sub.3 are the same as R and only one or two occurrences of each of R.sub.2 and R.sub.3 may be alkyl, and "n" is a whole number of from 1 to 9, and mixtures thereof.
