STEAM GENERATOR ADDITIVES TO MINIMINZE FOULING AND CORROSION IN CRUDE TOWERS

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 fouling and corrosion problems in the crude distillation tower and overhead condensing system of crude distillation units. The pKa of the dual amines should be in the range of about 5.7 to about 10.7, and the amine HCI salt volatility index should be about 2.1 or less.
