摘要： 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.

摘要： An improved laminar flow elbow system and method wherein the elbow system comprises a straight pre-pipe section to define the flow path of a fluid; the pipe section included directly prior to the inlet of a curved pipe section and having and comprising a plurality of vanes to impart a rotation to the fluid before passing through a curved pipe section to provide a generally flat velocity profile at the exit of the curved pipe section and to minimize turbulence of the fluid as it passes through the curved pipe section, and a substantially straight post-pipe section to define a flow path exit pipe section included directly at the exit of the curved pipe section, and containing a plurality of vanes to impart a backward rotation movement to the fluid flow from the exit of the curved pipe section, to substantially terminate rotation of the fluid upon exiting from the straight pipe section without substantial deterioration of the flatness of the fluid velocity profile and without generating substantial amounts of turbulence.

摘要： 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.
