Anti-corrosion e.g. acid corrosion, processing method for industrial plant e.g. crude oil distillation column, involves injecting neutralizing inhibiting species of corrosion to concentration and adapted rate for reducing corrosion rate

The method involves determining dew point temperature of gaseous fluid, and adjusting operating temperature of an industrial plant above the determined dew point temperature. Corrosion rate of distillation product is measured, and better neutralizing inhibiting species e.g. amines, of corrosion are...

Beschreibung
Zusammenfassung:	The method involves determining dew point temperature of gaseous fluid, and adjusting operating temperature of an industrial plant above the determined dew point temperature. Corrosion rate of distillation product is measured, and better neutralizing inhibiting species e.g. amines, of corrosion are determined at different rate for reducing the corrosion rate. The better neutralizing inhibiting species of the corrosion is injected to concentration and adapted rate for reducing the corrosion rate. Procédé pour le traitement anti-corrosion d'une unité industrielle, dans laquelle circule un fluide gazeux destiné à être condensé, le condensat comprenant une phase aqueuse acide, ce procédé étant caractérisé en ce que:- on détermine la température du point de rosée du fluide gazeux,- on ajuste la température de fonctionnement de l'unité industrielle au-dessus de la température de rosée ainsi déterminée,- on mesure la vitesse de corrosion du condensat,- on détermine les meilleures espèces neutralisantes inhibitrices de la corrosion, à différents débits, pour réduire la vitesse de corrosion,on injecte la meilleure espèce neutralisante inhibitrice de la corrosion, à la concentration et au débit adapté, pour réduire la vitesse de corrosion.
