ABSTRACT:
A randomly packed bed in a tower or column to prevent nesting of the packing elements and to improve physical stability and efficiency. Each packing element is a curved strip with one or more integral tabs or tongues depending downwardly from slots spaced longitudinally of the strips. Single or multiple rows and slots may be provided along the strip. Point-to-point contact between packing elements and substantially non-varying resistance to fluids flowing and improved mass transfer performance resulting from a more uniform packing density is assured.
