Abstract: The invention is a high capacity and high efficiency co-current vapor-liquid contacting apparatus for use in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by an arrangement of modules in horizontal stages rather than tray-like construction. The modules define a co-current contacting volume and in an exemplary configuration the modules include a liquid distributor, a demister, a receiving pan and a duct. The modules of one stage are rotated to be non-parallel with respect to the modules of an 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.

Abstract: The invention provides a vane-type mist eliminator device having formed or corrugated sheets, flat sheets, and integral louvers. The corrugated sheets and flat sheets are layered such that the arrangement of sheets and integral louvers creates at least one tortuous fluid flow channel from an inlet to a vapor outlet of the device An outer casing or frame is sufficient to hold the sheets together.
