Abstract

An apparatus comprises a column comprising a top, middle and bottom sections. The middle section is configured to receive a first stream comprising acrylonitrile, HCN, acetonitrile, and water. The column is configured to distill the first stream, and produce from the first stream a second stream, the second stream comprising water that is substantially free of acetonitrile. The column is configured to produce a third stream in the top section of the column, the third stream comprising acrylonitrile, HCN, and a portion of the water from the first stream. The column comprises a crude acetonitrile concentration zone defined by a baffle and an interior facing wall of the column. The column is configured to produce in an upper volume of the zone a stream comprising water and acetonitrile that is substantially devoid of acrylonitrile and HCN.
