Abstract
A mass transfer or heat exchange column is provided with a vapor distributor having, in one embodiment, a deflecting surface which directs a vapor stream about the inner periphery of the column. Following discharge from the distributor, the vapor stream contacts circumferentially spaced guide vanes which redirect the vapor stream toward the center of the column to cause a more uniform distribution of the vapor stream across the horizontal cross section of the column.
