Abstract: Methods for the prevention or mitigation of fouling in amine-treating systems comprising providing circulating aqueous amine solution and a hydrocarbon stream comprising at least one acid gas; and interacting the circulating aqueous amine solution with the hydrocarbon stream comprising the at least one acid gas to remove the acid gas from the hydrocarbon stream and entrain the acid gas into the aqueous amine solution. The circulating aqueous amine solution comprises entrained acid gas comprises foulant precursors; and polysulfide ions are introduced to react with the foulant precursors to decrease the rate of fouling within the circulating aqueous amine solution.
