Abstract: A method for removal of an organic amine from a hydrocarbon stream includes mixing the hydrocarbon stream including the amine with an aqueous inorganic acid in a volumetric ratio of hydrocarbon stream: aqueous inorganic acid of greater than 1.5:1 to 5:1, phase separating a hydrocarbon phase and an aqueous phase, removing the hydrocarbon phase, mixing the aqueous phase with an aqueous alkaline solution, phase separating the aqueous phase and an organic phase, and removing the organic phase. The aqueous inorganic acid has a concentration of greater than or equal to 30 weight percent. The disclosed method results in improved phase separation time during an amine removal process.
