Extraction tank ( Mixer settler) Ammonium sulfate extraction process, beckmann rearrangement, and after the separation in ammonium sulfate solution containing a small amount of still have lactam composition, extraction tank ( Mixer settler) Using benzene solvent extraction part to recycle is lactam. Through extraction, concentration of ammonium sulfate solution has lactam reduced from 1% to zero. 1%, extraction tank ( Mixer settler) Extractant concentration of benzene has been lactam was 4%. After extraction, the ammonium sulphate solution will still contain traces of benzene, and this part of the benzene can continue through the gas separation recycling formulation.
