摘要：
A vapor-liquid contacting tower having a tray deck, at least one downcomer and a structure packing layer in the space under the vapor-liquid bubble contacting tray wherein the tray deck has an opening such that vapor ascends upward through the opening to come into contact with the liquid flowing across the tray deck to form a froth in which the vapor and the liquid on the tray deck creates cross-flow bubble contact and with the structural dimensions of the tray deck and downcomer providing for at least 90 vol % of the total liquid flowing across the tray deck flows downwardly through the downcomer to the adjacent deck.
