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.

Abstract

An apparatus for providing electrochemical corrosion protection to a stainless steel process vessel comprises at least one anode in communication with the process vessel, a DC current supply having an electrical connection to the process vessel and an electrical connection to the at least one anode, and a potential control unit in communication with the DC current supply. The potential control unit has an electrical connection to the process vessel and an electrical connection to a reference electrode in communication with the process vessel, and is configured for adjusting current supplied by the DC current supply for passivating the process vessel. The apparatus is for use with a process vessel comprising at least one of duplex stainless steel and superaustenitic stainless steel.

Abstract

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.
