| 摘 要： | Liquid-lquid equilbrium(LLE)data of water-caprolactam-benzene-(NH4)2SO4 system at 303K were measured for extraction of caprolactam from aqueous ammonium sulfate solution.The influence of fluid flow rate,pulsation intensity on flooding velocity and mass transfer was studied for extraction of caprolactam from ammonium sulfate solution in a laboratory pulsed packed column.The flooding velocities and overall apparent heght of a transfer unit were given under various operation conditions.An industrial column developed based on above study is operated well.The scale-up effect is discussed.
