| Abstract: | The running state of the acetonitrile recovery unit before technology improvement was introduced. The problems affecting the long term running of the unit were discussed. The running period of the unit was prolonged through the technology improvements by purifying the feed,improving the drain way, renewing the washing water condenser and remolding the recovery tower. |
