RECYCLING OF COOLED OVERHEAD CONDENCED IN ACRYLONITRILE PURIFICATION PROCESS |
| 摘要 |
PROBLEM TO BE SOLVED: To provide an improved method for producing acrylonitrile. SOLUTION: In this method, an overhead stream from a cooling system of an acrylonitrile purification process is condensed and directly recycled to the cooling system as a part of a cooling liquid. The stream is condensed in a column or a partial condenser. COPYRIGHT: (C)2004,JPO&NCIPI
