The furnace of a delayed coking unit which is utilized for heating residue feeds to high temperatures can suffer from decrease in run length and fouling caused by caustic carryover from the upstream desalter unit. An antifoulant additive for preventing caustic induced fouling of thermal cracker furnace tubes is disclosed. The described antifoulant additive acts by converting the inorganic caustic compound such as NaOH to naphthenate salt of the metal as well as by reducing the fouling tendency of the whole feedstock, thereby making it ineffective in causing coking reaction. The additive finds application in thermal residue upgradation furnaces such as delayed coking unit, visbreaker, etc.
