A swirl tube (152) for positioning on a contact device, such as a tray (130), within a vapor liquid process column is disclosed. The swirl tube (152) includes a riser tube (156) having a venturi-shaped geometry, an inlet, and an outlet. The swirl tube further includes a separator (158) and means for movably coupling the separator to the riser tube proximate the outlet. Positioning such a swirl tube on a contact device improves the mass and/or energy transfer between vapor and liquid in the column, reduces or eliminates the flooding problem created by liquid entrained in descending vapor within the column, and reduces or eliminates the flooding problem created by vapor entrained in descending liquid within the column. |
