METHOD AND COMPOSITION FOR REDUCING COLD-END CORROSION

摘要

1. "METHOD AND COMPOSITION FOR REDUCING COLD-END CORROSION" The present invention is directed to a method of reducing the amount of corrosion due to sulfuric acid on metal parts at the cold-end of a combustion system and in contact with combustion gases derived from the combustion of sulfur-containing fuel, said method comprising adding to the combustion gases an effecting amount for the purpose of an additive comprising ethylene polyamine, optionally together with aliphatic water-soluble alkanolamine. The invention is also directed to a composition for use in such a method comprising ethylene polyamine and aliphatic water-soluble alkanolamine.
