规整填料的操作弹性和负荷性能图

Turndown Ratio and Loading Chart of Structured Packing

在文献报道的金属孔板波纹填料有关性能数据的基础上，讨论了规整填料的气、液负荷的上、下限，对它的操作弹性进行了分析，同时绘出了Mellapak250Y填料的负荷性能图。这将有利于规整填料塔的设计。

The higher and lower limits of gas and liquid loading of Mellapak 250Y are discussed on the basis ofrelevant data of properties of metal structured packing from the literature to analyze the tumdown ratio of Mellapak 250Y, and draw the loading chart, so as to facilitate the design of structured packing to column.
