ABSTRACT:
The present invention relates to a process for reducing the concentration of acrylontrile in an aqueous-acrylonitrile vapor stream. The process involves feeding the aqueous-acrylontrile vapor stream to a primary condenser maintained at a temperature and pressure so that a substantial amount of the water is condensed and the acrylonitrile is maintained in the vapor phase. The vapor containing the acrylonitrile from the first condenser is introduced to a secondary condenser maintained at a temperature and pressure so that substantially all the vapor is condensed. The condensate exiting the secondary condenser is introduced to a decanter where the acrylonitrile containing organic phase of the condensate is separated and recovered from the aqueous phase. The aqueous phase is recycled to the primary condenser to significantly reduce the acrylonitrile level in the aqueous phase and enhanced the separation.
