Anodic protection ( drop of tank)

Anodic protection ( drop of tank)

Anodic protection ( drop of tank)

Dear sirs:
We want any informations about how to determine the number of anods and their repartition in the drop of tank (oil-crude)

En français:

Chèr monsieur:
Nous avons besoin d'une documentation relative au calcul et pose des anodes sacrificielles sur un fond de Bac de stockage d'hydrocarbures liquides (pétrole brut)
Salutations distinguées

RE: Anodic protection ( drop of tank)

Is this actually a request for information on cathodic (not anodic) protection.

In either case, it should be recognized that the engineering designs of such systems are not trivial exercises.

RE: Anodic protection ( drop of tank)

It's really very simple.  

The number of anodes depends on the expected corrosion current and how this is distributed between the anodes while meeting their current density limits, which depend on the size and material of the anodes you select.  
The distribution of the anodes depends on the conductivity and volumetric shape of the corrosive solution and must be designed to optimize the primary current density delivered to the protected surface.
So, do you feel any wiser about doing this for yourself or will you call in a specialist (as is already recommended)?
