摘　　要：采用Aspen Plus软件对铝灰制取聚合氯化铝的过程建模,仿真优化结果表明,在温度80℃、盐酸质量分数20%和液固比10时PAC的产率最优;在优化条件下,H_(2)和NH_(3)的体积分数均低于爆炸极限;溶液的氨氮含量随温度升高而降低,随盐酸质量分数和液固比增加而上升。该模型设置灵活,可为铝灰制取聚合氯化铝的工艺优化和控制方案提供依据。By means of Aspen Plus software,a model is established for the aluminum dross to polyaluminum chloride(PAC)process.The simulation optimization results show that the optimal PAC yield is achieved under a temperature is 80℃,a hydrochloric acid concentration of 20%,and a liquid-solid ratio of 10.Under the optimized conditions,the volume fractions of H_(2) and NH_(3)are both lower than their own explosion limit.Ammoniacal nitrogen content in the solution decreases with increasing temperature,but increases with increasing hydrochloric acid concentration and liquid-solid ratio.This model is flexible in its settings,and can provide a basis for the optimization and control of the process for producing PAC from aluminum dross.
