摘　　要：建立了能描述规整填料塔中液体三维流动和混合的精馏过程混合池模型。对模型方程组的封闭性作了分析，并给出模型中液体流动分布和混合参数的计算方法。针对完整的三维混合池模型在求解计算上的费时，提出了适用于规整填料塔精馏过程的简化三维混合池模型和求解该方程的两步法。A three- dimensional mixing-pool model of a distillation column containing structured packing was established,in which liquid flow distribution and mixing were considered.The closure of model equations was analyzed and the methods of computing the flow and mixing parameters in the model were given.As the solution of an exact model is time consuming,a simplified model and the method of solution were proposed．
