ABSTRACT:
Inorganic phosphorus-containing acids and salts thereof in small amounts function as antifoulant additives in crude oil systems employed as feedstocks in petroleum refining which are subjected to elevated temperatures of from about 100.degree. to 1500.degree. F. and which are prone to produce fouling material that deposits and accumulates upon the surfaces of petroleum processing equipment, such as heat transfer equipment and the like. Such additives not only inhibit and suppress fouling but also reduce fouling in previously fouled refining systems.
