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.
Claims6
A process of deliquifying a waste stream containing solid inorganic particulate material and organic polymer contaminants obtained during the production of acrylonitrile to produce a substantially solid waste product comprising feeding the particulate containing waste stream including organic polymer contaminants into a dryer onto the outer surface of at least one heated drum, rotating said drum to facilitate removal of the liquid from said waste stream enabling the organic polymer contaminants present in the waste stream to form a tacky substantially solid material containing the particulate material which adheres to the surface of the drum, and removing the tacky solid material from the surface of the drum to obtain the solid waste product.
