STRUCTURED PACKING ASSEMBLY

摘要

Structured packing for mass-exchange or energy-exchange processes uses a stack of parallel, flat sheets forming flat channels therebetween. A number of tabs extends between adjacent pairs of sheets to form both bridges for fluid flow and spacers for structural rigidity of the packing. Some of the tabs serve predominantly to divert fluid over the entire surface of a given sheet to prevent so-called channeling, while other tabs are disposed to predominantly enhance fluid transfer between the adjacent sheets. Fluid communication between both sides of each sheet is facilitated due to perforations caused by the manufacturing of the tabs. The design allows for the use of very thin sheets resulting in a light-weight packing assembly.
