Wetted wires are a unique column internal with several advantages compared to spray and packed columns. These include near-perfect liquid distribution, extremely low pressure drops, and better heat or mass transfer due to droplet circulation. Currently, wetted-wire columns remain within the laboratory prototyping stage. The primary goal of this review is to present the current research on wetted-wire columns and to highlight the gaps that impede scale-up and commercialization. Initially, wetted-wire columns were proposed as an alternative to spray towers. However, wetted-wire columns occupy a space in between spray towers and packed columns. Therefore, wetted-wire columns should also be analyzed more like packed columns to increase the speed of technological translation. Wetted-wire column literature is presented by defining features (wire diameter, nozzle diameter, pitch, and material) and by performance indicators (operating range, pressure drop, hold-up, and separation efficiency). In addition, adjacent literature on wire-like structures is discussed.

湿丝塔：填充塔或喷雾塔的潜在替代品

湿丝是一种独特的塔内部结构，与喷雾塔和填充塔相比具有多种优点。这些包括近乎完美的液体分布、极低的压降以及由于液滴循环而实现的更好的传热或传质。目前，湿线色谱柱仍处于实验室原型设计阶段。本次综述的主要目标是介绍当前关于湿丝色谱柱的研究，并强调阻碍放大和商业化的差距。最初，湿线塔被提议作为喷雾塔的替代品。然而，湿丝塔占据了喷雾塔和填充塔之间的空间。因此，湿丝柱也应该像填充柱一样进行分析，以提高技术转化的速度。湿丝塔文献通过定义特征（丝直径、喷嘴直径、螺距和材料）和性能指标（操作范围、压降、滞留量和分离效率）来呈现。此外，还讨论了有关线状结构的相关文献。
