Filming Corrosion Inhibitors
Corrosion in crude unit operations, primarily in the crude tower overhead system, is commonly caused by the presence of hydrochloric acid, (HCl) formed in the crude tower as a result of Chlorides found in the crude feed. Corrosion can be severe enough that it results in unscheduled shutdowns costing the refiner millions of dollars in maintenance costs and lost opportunity.
Traditional corrosion control programs have used TOFA/DETA based imidazolines as film forming amines to create a protective hydrophobic film on the metal surface to keep the acidic water formed in the crude tower isolated from the metal surface.
Nelson Brothers is developing a range of surfactants that can be used to replace the standard TOFA/DETA imidazolines typically used as a film forming amine in crude tower overhead corrosion control programs. Learn more about our film-forming amines water treatment and contact us today.
