Abstract
Official abstract text for this publication.
A high capacity and high efficiency vapor-liquid contacting apparatus and process is useful in distillation columns and other vapor-liquid contacting processes. The apparatus is characterized by a half module comprising a downcomer against a shell of a vessel for transporting liquid to a subjacent stage which utilizes a demister to effect vapor-liquid separation at the downcomer outlet.
First claim
Opening claim text (preview).
1 . A process for vapor-liquid contacting, comprising the steps of: directing liquid through an inlet of a downcomer in a vessel; contacting liquid with a shell of the vessel or an outer wall of the downcomer adjacent to a shell of the vessel while descending in said downcomer; directing liquid from an outlet of the downcomer into a contacting volume; entraining the liquid in the vapor ascending in said contacting volume to flow co-currently into a demister; and separating the liquid from the vapor in the demister. 2 . The process of claim 1 further comprising: passing a separated liquid stream from the demister onto a transport deck. 3 . The process of claim 2 wherein said liquid directed through the inlet of said downcomer is from a superior receiving deck. 4 . The process of claim 1 further comprising cross-contacting the liquid on the transport deck with vapor passing through perforations on the deck from an inferior stage.
