After the revamp,the acrylonitrile in recovered acrylonitrile water can be fully separated and recovered acrylonitrile concentration can exceed 90%,which prevents the polymerization resistant component in recovered acrylonitrile water from affecting polymerization reaction process,ensures polymerization reaction activity,stabilizes polymerization process,and improves the NBR quality.
