Abstract: The process of the present invention comprises transporting a reactor effluent containing acrylonitrile/methacrylonitrile to a first column (quench) where the reactor effluent is cooled with a first aqueous stream, transporting the cooled effluent into an indirect contact cooler to condensed at least some of the cooled effluent to form a condensate comprising water and acrylonitrile/methacrylonitrile, transporting the remaining cooled gaseous effluent containing acrylonitrile/methacrylonitrile into a second column (absorber) where the cooled effluent is contacted with a second aqueous stream to absorb substantially all of the remaining acrylonitrile/methacrylonitrile into the second aqueous stream, transporting the second aqueous stream containing the acrylonitrile/methacrylonitrile to a first distillation column (recovery column) for separation of the crude acrylonitrile/methacrylonitrile from the second aqueous stream, and transporting the separated crude acrylonitrile/methacrylonitrile to a second distillation column (heads column) to remove at least some impurities from the crude acrylonitrile/methacrylonitrile, and transporting the partially purified acrylonitrile/methacrylonitrile to a third distillation column (product column) to further purify the acrylonitrile/methacrylonitrile, and recovering the purified acrylonitrile/methacrylonitrile, wherein the improvement comprises transporting the condensate formed in the indirect contact cooler to a decanter where the condensate is separated into an organic phase comprising acrylonitrile/methacrylonitrile, an aqueous phase and a vapor phase, and the organic phase is introduced into the recovery column without passing through the absorber column.

Abstract: A process for manufacturing an unsaturated mononitrile selected from the group consisting of acrylonitrile and methacrylonitrile comprising reacting an olefin selected from the group consisting of propylene and isobutylene, ammonia and oxygen in a reactor zone in the presence of a catalyst to produce a reactor effluent containing the corresponding unsaturated mononitrile, transferring the reactor effluent containing the unsaturated mononitrile to a quench column wherein the reactor effluent containing the unsaturated mononitrile is contacted with at least a first aqueous stream to cool the reactor effluent, transferring the cooled reactor effluent containing the unsaturated mononitrile to an absorption column wherein the reactor effluent containing unsaturated mononitrile is contacted with at least a second aqueous stream to separate and remove the unsaturated mononitrile as a bottom stream from the absorption column, transferring the bottom stream containing the unsaturated mononitrile to a recovery and purification section where the unsaturated mononitrile is recovered and purified, and recycling at least one aqueous process stream to improve the efficiency of the process wherein the improvement comprises treating at least one aqueous stream before recycling into the process stream to reduce the pH thereby reducing the amount of trace impurities present in the aqueous recycle stream.
