ANTI FOULING AGENT FOR HYDROCARBONS ANTIFOULING

The present invention concerns a method for reducing or eliminating fouling deposits which are encountered in the processing of hydrocarbon and/or petrochemical streams, particularly at higher temperatures. The objective is achieved by adding to the stream an antifouling amount of a composition comp...

Beschreibung
Zusammenfassung:	The present invention concerns a method for reducing or eliminating fouling deposits which are encountered in the processing of hydrocarbon and/or petrochemical streams, particularly at higher temperatures. The objective is achieved by adding to the stream an antifouling amount of a composition comprising (i) an alkyl or alkenyl substituted bis succinimide; (ii) the reaction product of an aliphatic carboxylic acid and an alkylene polyamine; and (iii) an N-phenyl N' (1,3 dimethyl butyl) p - phenylene diamine compound.
