A process for providing a liquid residue to an ammoxidation process stream, the process comprising: passing a reactor effluent gas comprising acrylonitrile, HCN, acetonitrile, water vapor and impurities to a quench column, contacting the reactor effluent gas with quench liquid in the quench column, to provide: (a) a quench column bottoms stream containing water and impurities which is removed through a conduit and sent to waste treatment, and (b) a stream of cooled reactor effluent gases; passing the cooled reactor effluent gases to a quench aftercooler, feeding the cooled quench effluent from the quench aftercooler to an absorber and feeding wash water which enters at the top of the absorber, and removing from the absorber: (a) non-condensable gases, and (b) an aqueous solution containing water, acrylonitrile, acetonitrile and impurities which is removed as a bottoms stream; passing the bottoms stream to an extractive distillation column, and introducing solvent water to the top of extractive distillation column to perform extractive distillation, and removing from the extractive distillation column: (a) acrylonitrile and HCN as an overhead vapor which is sent to further purification, (b) a stream containing acetonitrile and water, and (c) a bottoms stream containing water, heavy organics and other impurities; passing the stream containing acetonitrile and water from the extractive distillation column to a stripper, to which heat is added, and removing from the stripper: (i) acetonitrile as an overhead vapor, and (ii) a liquid stream containing mostly water from the lower half of stripper; providing the bottoms stream containing water, heavy organics and other impurities from extractive distillation column as a process stream to an evaporator system having one or more evaporation stages, separating water from the heavy organic impurities in the evaporator system having one or more evaporation stages to provide an aqueous condensate and a liquid residue, and contacting the liquid residue with the reactor effluent in the quench column to provide a quench columns bottom stream comprising ammonium sulfate and polymer; wherein the amount of ammonium sulfate and the amount of polymer in the quench column bottoms stream are defined by a formula y = -M1x + C1 where y is a weight % of ammonium sulfate, x is a weight % polymer, M1 is 4.6 and C1 is 45 or less. passing a reactor effluent gas comprising acrylonitrile, HCN, acetonitrile, water vapor and impurities to a quench column, contacting the reactor effluent gas with quench liquid in the quench column, to provide: (a) a quench column bottoms stream containing water and impurities which is removed through a conduit and sent to waste treatment, and (b) a stream of cooled reactor effluent gases;
