An apparatus for providing electrochemical corrosion protection to a process vessel comprises at least one anode positioned at a first height above a floor of the process vessel and at least one anode positioned at a second height above the floor of the process vessel, a DC current supply that is electrically coupled to the process vessel, to the at least one anode positioned at the first height and to the at least one anode positioned at the second height, and a potential control unit in communication with the DC current supply. The potential control unit is electrically coupled to the process vessel and to a reference electrode, the reference electrode being in communication with the process vessel. Current supplied by the DC current supply for passivating the process vessel is adjustable by the potential control unit. |
