Abstract
A process for removing amine compounds from a process stream derived from a carbonylation process. The amine compounds may be present as iodide salts. The process stream also contains corrosion metal contaminants. The amine compounds are removed by mixing a portion of the process stream a slipstream to form an aqueous stream having a water concentration of greater than 50 wt. %. The aqueous stream is contacted with an exchange resin to remove amine compounds, as well as corrosion metal contaminants.
