The invention generally relates to processes for reducing and removing foulant and foulant precursors from regenerated amine mixtures and to equipment useful in such processes. Such amine mixtures are useful for removing one or more acidic gases such as COor HS from olefin hydrocarbon streams. A first feed comprising regenerated amine, foulant, and foulant precursors is provided. A second feed comprising aromatic hydrocarbons is provided. The first and second feeds are combined and then separated to form first and second products. The first product is an upgraded regenerated amine mixture that comprises the first feed's amine. The second product comprises second feed's aromatic hydrocarbons and a portion of the first feed's foulant.
