Abstract: A process for manufacturing acrylonitrile comprising reacting propylene, ammonia and oxygen in a reactor zone in the presence of a catalyst to produce a reactor effluent containing crude acrylonitrile, transferring the reactor effluent containing crude acrylonitrile to a quench column wherein the reactor effluent containing crude acrylonitrile is contacted with an aqueous stream to cool the reactor effluent, transferring the cooled reactor effluent containing the crude acrylonitrile to an absorption column wherein the reactor effluent containing crude acrylonitrile is contacted with a second aqueous stream to separate and remove the crude acrylonitrile as a bottom stream from the absorption column, transferring the bottom stream containing the crude acrylonitrile to a recovery and purification section where the acrylonitrile is recovered and purified, wherein the improvement comprises supplying the second aqueous stream to the absorption column by means of liquid spray nozzles.

Abstract: A process increasing the yield of both HCN and acetonitrile produced during the manufacture of acrylonitrile comprising introducing a hydrocarbon selected from the group consisting of propylene and propane, a crude ketone and/or a mixture of at least two ketones, ammonia and air, into a reaction zone containing an ammoxidation catalyst, reacting the hydrocarbon, the ketone, ammonia and oxygen over said catalyst at an elevated temperature to produce acrylonitrile, hydrogen cyanide and acetonitrile, and recovering the acrylonitrile, hydrogen cyanide and acetonitrile from the reactor.

Abstract: The method of acrylonitrile or methacrylonitrile recycling produced from the reactor flow of the reaction of aminooxidations of propylene or isobutylene consists in the admission in the reactor flow through absorption column of a first decanter, recycling column, second decanter and stripping column. The inner tenperature of the first and second decanters is maintained between 0 deg.C and 23.9 deg.C. 7 claims, 1 figure

Abstract: The invention relates to a method for the manufacturing of unsaturated mononitrile from the group of acrylonitrile and methacrylonitrile. It includes reaction of olefine from the group containing propylene or isobutylene and ammonia and oxygen in a reaction zone in the presence of a catalyst to produce a reactor effluent containing the corresponding unsaturated mononitrile. The effluent runs over a cooling column where, in order to cool, it gets into contact with at least first aqueous stream. The cooled reactor effluent containing the unsaturated mononitrile is transferred into an absorption column where it is contacted with at least a second aqueous stream to separate and remove the unsaturated mononitrile as a bottom stream from the absorption column. The bottom stream containing the unsaturated mononitrile is transferred to a recovery and purification section where the unsaturated mononitrile is recovered and purified. At least one aqueous process stream is recirculated for improving the efficiency of the process consisting in reducing the pH, thereby reducing the amount of trace impurities in the aqueous recirculation stream. 8 claims, 1 figure

Abstract: By the method raw acentonitrile containing acrylonitrile asan impurity, and water is supplied in the upper part of thedistillation column. The raw acetonitrile is distilled in thepresence of water for a period of time where the entireacrylonitrile admixture is evaporated in the presence of thewater, the entire acrylonitrile is removed in an upper streamcoming out of the distillation column, and the raw acetonitrile isrecovered free from any acrylonitrile admixture from the lowerpart of the column. The attached figure is a flow chart of theflows in accordance with the invention and is described in greaterdetail in the description.16 claims, 1 figure
