In this paper, a newly designed distillation column consisting of a wetted wall with a rectangular cross section is analyzed and compared with a conventional packed column with regard to the operating range of both apparatuses. As expected, the pressure drop is considerably lower in the wetted‐wall column and, therefore, it offers a higher range of operation. However, in the wetted‐wall column, the separation efficiency decreases rapidly with increasing F factors. This effect can be overcome by the serial connection of two wetted‐wall columns.

湿壁塔与填充塔的蒸馏操作范围比较

在本文中，分析了一种新设计的蒸馏塔，该蒸馏塔由具有矩形横截面的湿壁组成，并且在两种设备的操作范围方面与常规填充塔进行了比较。如预期的那样，湿壁塔中的压降要低得多，因此，它提供了更大的操作范围。但是，在湿壁塔中，分离系数随着F因子的增加而迅速降低。通过串联两个湿壁色谱柱可以克服这种影响。
