| titleOfInvention | Waste stream improvement in the simultaneous propylene oxide/styrene manufacturing process |
| abstract | Contacting the organic stream with water and carbon dioxide, thereby extracting sodium from the organic stream, and separating the sodium salt-containing aqueous phase from the organic phase comprising a reduced sodium content. The organic stream may be a heavy residue formed from the co-production of propylene oxide and styrene. Contact is by combining the carbon dioxide and water, CC 2 - a combination of contacting the saturated water stream and the organic stream, and / or the organic stream and the water-to form a saturated stream, and the CC 2 It may include forming a mixture and injecting the carbon dioxide as a gas into the mixture. The method further comprises repeating the contacting and the separation one or more times with the organic phase, subjecting the organic phase to ion exchange, or both, to obtain an organic phase with a further reduced sodium content. It may contain additionally. A system for performing the method is also provided. |
