VERFAHREN ZUR GEWINNUNG UND REINIGUNG VON ACRYLNITRIL ODER METHACRYLNITRIL |
摘要 |
<p>A multi-stage evaporator is used to remove water from the extracted distillation or stripper tower bottoms recycled as quench liquid to the quench tower of an acrylonitrile purification and recovery system. This results in a significant decrease in the amount of waste quench tower bottoms produced by the system. Use of a multi-effect evaporator represents a significant energy savings as compared with other techniques for decreasing the water content of the recycle stream.</p> |
