Performance improvement of sacrificial anode cathodic protection system for above ground storage tank
This study presents a controlled sacrificial anode (magnesium anodes) cathodic protection system for aboveground storage tanks. The proposed method is able to control the anode's current, which leads to enhance the performance of anodes, therefore, increase the anode's lifetime. The proposed system has been implemented in a laboratory based tank contains saline water (5661 ppm) In this experiment, the overprotection and anode energy loss were eliminated, and the anodes lifetime has been extended 35.55 times higher compared to the conventional system. The proposed method reduced the protection current and stabilized the system overall.
