  • Method and apparatus for providing electrochemical corrosion protection
    Patent number: 8608913
    Abstract: An apparatus for providing electrochemical corrosion protection to a process vessel, the apparatus comprises at least one anode in communication with the process vessel; a DC current supply being electrically coupled to the process vessel and to the at least one anode; 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 in communication with the process vessel. The current supplied by the DC current supply for passivating the process vessel is adjustable by the potential control unit. The process vessel may comprise at least one of duplex stainless steel and superaustenitic stainless steel.
