Vanadium Corrosion Inhibitor General Description MGV-200G is one of the highest concentration and purest turbine-quality,totally oil-soluble, organometallic magnesium hydroxide base fuel additive in the industry. MGV-200G is used to passivate high temperature corrosion caused by vanadium found in crude and residual/heavy grade fuel oils. No dilution or blending is required. MGV-200G provides a minimum of (20%) active megnesium in a non-abrasive and ready-to-use,highly soluble form. We supply a complete range of Vanadium inhibitors to treat heavy fuel oil and/or crude oil fired in combined cycle gas turbines and steam boiler units for power generation applications. The grades that we supply are the most advanced in this field.z
