Abstract
A method of using substituted olefin polymers prepared by reacting one or more C2-C10 mono-olefin polymers having a number average molecular weight of about 300 to about 5,000 with C4-C10 monounsaturated dicarboxylic acid derivatives and compositions comprising the substituted olefin polymers for preventing fouling of hydrocarbon processing equipment, especially ethylene dichloride distillation units.
Claims19
A method of preventing fouling of hydrocarbon processing equipment in contact with hydrocarbon fluids containing between 3.7% and 15.3% ethylene dichloride during processing of said hydrocarbon fluids comprising adding to said fluids an effective antifouling amount of one or more substituted olefin polymers prepared by reacting one or more C2-C10 olefin polymers having a number average molecular weight of about 150 to about 5,000 with one or more C4-C10 monounsaturated dicarboxylic acid derivatives.
A composition comprising one or more organic solvents and about 5 to about 80 weight percent of one or more substituted olefin polymers prepared by reacting one or more C2-C10 mono-olefin polymers having a number average molecular weight of about 150 to about 5,000 with one or more C4-C10 monounsaturated dicarboxylic acid derivatives.
