This invention relates to the reduction of sulfidation or sulfidic corrosion and the reduction of depositional fouling in general and in particular the reduction of sulifidation/sulfidic corrosion and the reduction of depositional fouling in heat transfer components, which include but are not limited to heat exchangers, furnaces and furnace tubes located in refining facilities and petrochemical processing facilities and other components used for transporting or conveying process streams, which may be prone to fouling. In particular, the present invention relates to the reduction of corrosion and fouling associated with process streams. The present invention is directed to a method of reducing fouling in a heat transfer component, which combines the use of a corrosion resistant material having the desired surface roughness with the application of vibration, pulsation and internal turbulence promoters.
La présente invention concerne la réduction de la sulfuration ou de la corrosion sulfurique et la réduction de l~encrassement par dépôt de manière générale et en particulier la réduction de la sulfuration/corrosion sulfurique et la réduction de l~encrassement par dépôt des composants de transfert thermique, qui comprennent mais sans s~y limiter, des échangeurs thermiques, des fours et des tubes de four situés dans des dispositifs de raffinage et des dispositifs de traitement pétrochimique et d'autres composants utilisés pour transporter ou déplacer des flux de traitement, qui peuvent être enclins à un encrassement. En particulier, la présente invention concerne la réduction de la corrosion et de l~encrassement liés aux flux de traitement. La présente invention concerne un procédé de réduction de l~encrassement dans un composant de transfert thermique, qui combine l'utilisation d'un matériau résistant à la corrosion ayant la rugosité de surface souhaitée à l'application d~un promoteur de vibration, d~impulsion et de turbulence interne.
