  • Surface passivation technique for reduction of fouling
    Patent number: 8092618
    Abstract: The invention provides a method and apparatus for controlling the formation of foulant deposits on petroleum processing equipment. The invention involves a first mixture comprising an acid phosphate ester. The first mixture is applied to the surface of the petroleum processing equipment at a high temperature. Then a second mixture comprising a metal salt is applied also at a high temperature. The result is sufficient to provide an effective coating that prevents the formation of foulant deposits on the petroleum processing equipment. The second mixture reacts with any polyphosphate in the coating to prevent any contamination of petroleum materials within the petroleum processing equipment.
