规整填料精馏塔的设计计算

Calculation and design of distillation columns containing structured packing

通过大量的文献调研，比较了规整填料精馏塔和板式塔的优缺点，对规整填料精馏塔内压降、传质及液泛时压降的计算公式进行了比较，总结出设计计算规整填料精馏塔的步骤与方法，为规整填料精馏塔的应用提供了基础。

n the basis of a great deal of investigations and studies on literatures the advantages and disad-vantages of distillation columns containing structured packing and plate columns were compared,Cal-culation models about pressure drop,mass transfer and pressure drop at flood point in distillation columns containing structured packing were considered.A calculation and design method for distilla-tion columns containing structured packing was given out.This method will provide a basis for the ap-plication of distillation columns containing structured packing.
