Abstract
Laboratory experiments have demonstrated the corrosivity of a contaminated N-methyldiethanolamine solution from a refinery can be reduced by adding caustic or a proprietary neutralizer. A model formic acid contaminated amine solution was shown to have similar behavior.
Laboratory studies have shown there is a definite decrease in corrosivity as the pH of the amine solutions increase. Three possible mechanisms for the observed pH corrosivity behavior are discussed.
Plant experience that demonstrates the usefulness of neutralization and a novel method for dissolved solids removal are presented
