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.
