In accordance with the teachings of the present invention, a method is provided for analyzing RFT data from a data file. The method includes parsing the data file into pipe lengths, calculating a phase profile for the data points within each pipe length, locating potential defects in the pipe length using the phase profiles, determining for each defect a total equivalent phase shift as a combination of a circumferential equivalent phase shift and a non-circumferential equivalent phase shift, and using the total equivalent phase shift to analyze the defect.

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 slots caused by the punching of the tabs. Preferably, the tabs or even entire sheets are perforated as well to facilitate fluid wetting of downward-faced portions of the tabs thus reducing &ldquo;dry zones&rdquo; on the packing.
