Extraction Method to Remove Impurities from Aqueous Mixture |
| abstract |
The present invention extracts an aqueous mixture or a purified aqueous mixture with an extraction solvent in the extraction zone to form an extract stream and a raffinate stream, and optionally, separates the extract stream and the solvent-rich stream in a separation zone to achieve a high boiling point. A method is provided for removing impurities from an aqueous mixture or a purified aqueous mixture by forming an organic impurity stream and withdrawn extraction solvent stream. |
