Abstract: A process for the enhanced recovery of hydrogen cyanide (HCN) obtained from the reactor effluent of an ammoxidation reaction of propylene or isobutylene comprising passing the reactor effluent through a quench column, an absorber column, a first distillation column, a second distillation column, a cooler and a knock-out pot, wherein the improvement comprises contacting the vapor phase containing hydrogen cyanide with an aqueous stream.

Abstract: A process for the reduction in the amount of waste material generated during the manufacture of acrylonitrile comprising introducing an additional amount of oxygen containing gas, preferably air, in the substantial absence of any oxygenate compounds, into the upper portion of the fluid bed reactor to react with at least some of the unreacted ammonia to reduce the amount of unreacted ammonia present in the reactor effluent.
