<p>A mass transfer or heat exchange column is provided with a vapor distributor which circulates a vapor stream about the inner periphery of the column (522). The vapor stream is discharged from the distributor through an at least partially open bottom (542) and, optionnally, a plurality of spaced apart outlet ports (540) in an annular wall (526) of the distributor. A deflector (542) extends upwardly along the inner annular wall to deflect the vapor stream away from a circumferential path.</p> |
