Zusammenfassung: | The present invention relates to a method of protection against corrosion in refining process units of crude oil contaminated with organic chlorides through the application of anticorrosive compounds, based on rare earth salts. Said salts include neodymium and praseodymium salts, used as additives, with the distinctive element of being nitrogen-free and suitable for service at high temperatures, designed to extend the useful life of facilities and processes associated with oil refining and the petrochemical industry.
La invención que se presenta consiste en un método de protección contra la corrosión en unidades de proceso de refinación del crudo contaminado con cloruros orgánicos a través de la aplicación de compuestos anticorrosivos basados en sales de tierras raras, tales como sales de neodimio y praseodimio, utilizados como aditivos, con el elemento distintivo de ser libres de nitrógeno y aptos para servicio a altas temperaturas, diseñados para alargar la vida útil de las instalaciones y procesos asociados a la refinación de petróleo y la industria petroquímica. |
