MAGNESIUM ANODES in a Chemical Plant

Magnesium anodes are useful under conditions where accessibility is difficult and electrical facilities unobtainable. At the Dow Chemical Co.'s Freeport, Texas, plant the principal use for magnesium anodes has been in structures handling large volumes of sea water and brine, both static and in motion. The following article, based on a paper presented at a meeting of the National Association of Corrosion Engineers, describes some of the cathodic protection studies made by Mr. Osborn, who has been responsible for an extensive programme developing the use of magnesium in cathodic protection.
