Abstract: A process for the recovery of unreacted ammonia from the effluent from a reaction zone used to produce acrylonitrile or methacrylonitrile comprising quenching the reactor effluent with an aqueous solution of ammonium phosphate in at least two stages, thereby capturing the ammonia component of the effluent. The captured ammonia may be recovered by heating the aqueous ammonium phosphate, which then may be recycled. Contaminants present in the aqueous ammonium phosphate may be removed, for example by solvent extraction or wet oxidation, prior to recycle.

Abstract: A process for the substantial reduction or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.

Abstract: By the method, the ammonium sulphate formed during themanufacture of acrylonitrile is considerably reduced or completelyeliminated by means of direct amoxydation (reaction betweenammonia and oxygen) of propylene/propane, ammonia and oxygencontaining gas, e.g. air, on a catalytic fluid bed. Methanol isintroduced in the upper part of the reactor used at a point whereit reacts with the residual ammonia without this affecting theacrylonituile yield. The methanol is introduced in the reactor ata temperature under the point of its selfignition. When catalystis used for fluid bed, poor in oxygen, ogygen conraining gas inintroduced in the reaction at a distance from 20.32 and 30.48 cmfrom the place of methanol feeding.
