PROCESS FOR RECOVERY OF ACRYLONITIRLE

摘要

A process for the recovery of acrylonitrile from an ammoxidation reactor effluent stream containing acrylonitrile, water and organic impurities including passing an absorber bottoms stream through a single recovery/stripper column (80), generating an acrylonitrile-rich overhead stream (96), a lean water side stream (84), and a recovery/stripper bottoms stream (92) containing organic impurities, wherein the acrylonitrile-rich overhead stream is passed into condenser (98) and into a decanter (100) to separate water from the acrylonitrile.
