  • Phosphorus containing compounds as antifoulants in ethylene cracking furnaces
    Patent number: 4105540
    Abstract: Phosphate and phosphite mono and diesters in small amounts function as antifoulant additives in ethylene cracking furnaces which are subjected to elevated temperatures from about 500.degree. - 1700.degree. F. These furnaces produce material that deposits and accumulates upon furnace surfaces including furnace coils and transfer line exchangers. The present antifoulant additives inhibit and suppress fouling and also help clean up previously fouled furnace surfaces.
