Method of and apparatus for vapor distribution

摘要

A vapor horn-packing bed assembly for a chemical process tower incorporating a plurality of directional flow vanes within a 360 degree annular housing. A structured packing bed is disposed centrally of the annular housing and the vapor horn is disposed in flow communication with the packing bed wherein discharged vapor will ascend therethrough. The vapor horn includes a plurality of equally spaced flow vanes positioned for intercepting and diverting the vapor flow downwardly within the tower for generating a substantially homogenous vapor region beneath the packing bed. The homogenous vapor generated by such a vapor horn will comprise a turbulent, gaseous region having sufficiently uniform kinetic energy to present a substantially even ascension front into the packing bed of the vapor horn assembly and other packing beds thereabove.
