ABSTRACT:
A process for deliquifying a solid particulate containing liquid waste stream including organic contaminants produced during the production of acrylonitrile comprising feeding the waste stream onto the outer surface of a heated drum(s) rotating the drum(s) to facilitate removal of the liquid to produce a substantially solid material which adheres to the surface of the drum(s) and is subsequently removed.
