In order to decrease the concentration of diluted ammonia water emissions in synthetic ammonia process , the ammonia water stripping process was simulated based on Aspen Plus software.Under satisfying the condition that ammonia content in the tower bottom was less than 0.5%, the suitable operation parameters were obtained for the air stripping tower .The feeding temperature of ammonia water was 60℃, number of theoretical tower plates was 6, the feeding air flow was 500 kg/h, and the diameter of the stripping tower was 1.4 m with φ50 steel INTX packing selected.
