多罐复合式分批精馏塔的设计

摘要为了开发多罐复合塔简单易行的设计方法，建立了多罐复合塔的恒摩尔持液模型，并用平衡程度系数概念考察了全回流过程中塔内各板和各罐内接近平衡的情况，在综合考虑所需塔板数和操作时间的基础上提出了设计中确定全回流操作终点的方法，给出了多罐复合式分批精馏塔的设计方法，该方法确定的板数能较好地完成分离任务。

Abstract： To develop a feasible design method for a multi-effect batch distillation column (MEBAD), constant holdup model was built and the coefficient of approaching equilibrium was used to examine the degree of approaching equilibrium under total reflux for MEBAD. On the basis of comprehensive consideration of the number of stages and operation time required, the criterion for the end of total reflux operation in design was proposed. Finally, the design method for the emerging column was given, which could fulfill the separation task perfectly.

Keywords： batch distillation column； multi-effect batch distillation column(MEBAD)； total reflux operation； design； constant holdup model
