摘要： A distillation column and method in which a plurality of beds of structured packing are provided within a column shell and are configured to contact liquid and vapor phases of the mixture to be distilled. At least one liquid redistributor is located between the beds of structured packing to redistribute the liquid of the liquid phase and an annular collector is located above the liquid distributor to direct liquid to the liquid distributor. The annular collector acs as a constriction to produce a central flow of the vapor phase which can result in decreased performance of overlying beds of structured packing. In order to overcome this potential problem, a truncated bed of structured packing is provided directly above the annular collector to promote a more uniform distribution of such central vapor flow in a transverse direction of the column shell. The truncated bed of structured packing is fabricated from layers of structured packing each having a height less than that of packing layers of overlying beds of structured packing.
摘要翻译：一种蒸馏塔和方法，其中在柱壳内设置多个规整填料床，并且构造成接触要蒸馏的混合物的液相和蒸汽相。至少一个液体再分布器位于规整填料床之间，以重新分配液相的液体，并且环形收集器位于液体分配器上方以将液体引导至液体分配器。环形收集器作为收缩部产生气相的中心流，这可导致规整填料的上层床的性能降低。为了克服这个潜在的问题，在环形收集器的正上方提供了一个规整填料的截顶床，以促进这种中心蒸气流在柱壳的横向方向上更均匀的分布。规整填料的截顶床由具有小于规整填料上覆层的填料层的高度的规整填料层制成。

摘要： A structured packing element comprises a plurality of corrugated sheets and one planar member positioned adjacent to each of the corrugated sheets. The planar member has a top edge and a bottom edge that are at least proximally aligned with the top and bottom edges respectively of the corrugated sheets. The planar member is further characterized by a middle portion having an open area percent that is higher than the open area percents of the top and bottom portions of the planar member. The structured packing element can be used to form structured packings for distillation applications.
摘要翻译：规整的填充元件包括多个波纹片和邻近每个波纹片定位的一个平面构件。平面构件具有顶部边缘和底部边缘，其分别与波纹片材的顶部和底部边缘至少向近侧对准。平面构件的特征还在于具有开口面积百分比高于平面构件的顶部和底部的开口面积百分比的中间部分。结构化填充元件可用于形成用于蒸馏应用的结构填料。
