ABSTRACT:
Waste water produced in an acrylonitrile plant and containing significant amounts of acrylonitrile and acrylic acid is processed so as to reduce its organics content for disposal purposes and to recover the acrylonitrile and acrylic acid contained therein. The waste water is treated by contact with activated carbon to adsorb the organics contained therein. The activated carbon is periodicaly regenerated with a desorbing liquid and the desorbate product is distilled to yield acrylonitrile and acrylic acid. Every fifth regeneration cycle, the activated carbon is regenerated thermally rather than means of a liquid in order to restore its activity to its original value.
