Patent number: 10184091Abstract: A process based on the combined use of yttrium and magnesium to inhibit vanadium corrosion of high temperature parts of thermal equipment. The combined use of yttrium and magnesium, applied in a variable yttrium/magnesium ratio, compared with conventional magnesium inhibition, may reduce emission of magnesium vanadate and minimize losses of performance due to fouling of the high temperature parts, including in the presence of alkali metals. Further, compared with inhibition based on yttrium alone, it may reduce the inhibition cost and reinforce the protection against combined vanadium pentoxide and sodium sulfate corrosion.Type: GrantFiled: December 2, 2016Date of Patent: January 22, 2019Assignee: General Electric CompanyInventors: Pierre Olivier Montagne, Sundar Amancherla, Krishnamurthy Anand, David Terry Trayhan, Jr., Matthieu Paul Frederic Vierling, Maher Aboujaib, Abdurrahman Abdallah Khalidi
