    摘要: Dual action amines provide corrosion protection from corrosion and fouling for a steam generator system and distillation tower of a petroleum or petrochemical refinery. These amines are chosen to provide protection for the steam condensate section of the boiler while simultaneously minimizing amine salt fouling and corrosion problems in the crude distillation tower and overhead condensing system of crude distillation units. The distribution ratio of the dual action amine should be about 4.0 or less, the amine pKa should be in the range of about 7.0 to about 11.0, and the amine HCl salt volatility index should be about 2.5 or less.
