| 摘要 |
The invention is a high capacity and high efficiency co-current vapor-liquid contacting apparatus for use in distillation columns (10) and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of modules (20) in horizontal stages rather than tray-like construction. The modules define a co-current contacting volume (56) and in an exemplary configuration the modules (20) include a liquid distributor (22), a demister (24), a receiving pan (26) and a duct (28). The modules of one stage are rotated to be non-parallel with respect to the modules of a n inferior stage, a superior stage, or both. Variations relate to the design of the individual elements such as the demister, liquid distributor, ducts, and contacting volumes, and the overall arrangement of the apparatus.
