Vanadation  Method of protecting stable magnetite layer from corrosion  Must reduce V5+ and deposition on surface  Steady state is reached when V5+ : V2O5 is 0.4  If ratio less than 0.3 - rapid break down and corrosion  High levels can lead to degradation of DEA

. Vanadation  Method of protecting stable magnetite layer from corrosion  Must reduce V5+ and deposition on surface  Steady state is reached when V5+ : V2O5 is 0.4  If ratio less than 0.3 - rapid break down and corrosion  High levels can lead to degradation of DEA  Most plants have a slow reduction of V5+ to V4+  Can counter by addition of KNO2
