A vapor distributor for use in an internal region of a mass transfer column to receive and redistribute a vapor stream when it is introduced radially into the internal region through a radial inlet in a shell of the mass transfer column. The vapor distributor includes a plurality of multiple-sided elongated deflectors arranged in a descending array and a pair of braces that extend longitudinally across the array of elongated deflectors and hold them in spaced apart and side-by-side relationship to each other. Each of the elongated deflectors has a deflecting surface that faces toward the radial inlet to redirect and redistribute the radially-introduced vapor stream. The braces each include a strut that may also redirect and redistribute the vapor stream.

A cross-corrugated structured packing element is provided for use in mass transfer or heat exchange columns. The packing element has a plurality of packing layers positioned in an upright, parallel relationship to each other and including corrugations formed of alternating peaks and valleys and corrugation sidewalls extending between the peaks and valleys. The packing element also includes a plurality of apertures each presenting an open area. The apertures are distributed such that the corrugation sidewalls have a greater density of open areas than any density of the open areas that may be present in the peaks and valleys. Some of the apertures may be present in the peaks and the valleys to facilitate liquid distribution. The apertures may also be placed in rows or other patterns that are aligned in a direction along a longitudinal length of the corrugations. Regions with a larger apex radius may be formed in the peaks, such as by depressing spaced-apart segments of the peaks to form spacers in the undepressed portions of the peaks. Some of the apertures may be positioned in the transitions from the depressed portions of the peaks to the unmodified apex sections.

A method of determining one or more bulk rheological properties of a particle laden fluid comprising providing a system comprising a vessel, a pump coupled to the vessel, and a flow-through apparatus coupled to the pump and the vessel, wherein the flow-through apparatus comprises a flow chamber, a bob rotatably disposed within the chamber, wherein the bob comprises an outer geometry adapted for continuous laminar flow in an axial direction, and a gap between the chamber and the bob, pumping the particle laden fluid into the flow-through apparatus, shearing the particle laden fluid within the gap of the flow-through apparatus, and collecting data from the bob and observing the particle laden fluid to determine one or more bulk rheological properties of the particle laden fluid.
