摘要

Procedure to inhibit the attack to heat exchangers by petroleum derivatives, in a process in which a hydrocarbon charge is passed in direct heat exchange contact with a heat exchanger surface at a surface temperature of approximately 37.6º C to 1.093, 3º C to heat said load to a processing temperature: the improvement comprising the inhibition of organic and inorganic deposits or scale from said hydrocarbon charge in said heat-exchanger surface by incorporating in said charge an N-alkyl phosphoric acid selected from the group consisting of : ** (See formula) ** and mixtures thereof, wherein R1, R2, R3, R4, R5, and R6 are radicals selected from the group consisting of hydrogen, alkyl, alkenyl, alkaryl, aryl, cycloaliphatic, cycloheteryl, and the foregoing radicals having substituents on the same, with the proviso that in at least one case one of the above radicals contains at least eight carbon atoms.
