ABSTRACT:
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. The vapor stream is discharged from the distributor through an at least partially open bottom and, optionally, a plurality of spaced apart outlet ports in an inner annular wall of the distributor. A deflector extends upwardly along the inner annular wall to deflect the vapor stream away from a circumferential flow path along the inward face of the wall. The deflector may also extend outwardly under the flow channel to deflect, in a radially inward direction, vapor exiting the flow channel through the open bottom of the distributor.
