Structured packing efficiency-Vital information for the chemical industry

► Measured data on structured packing efficiency often differ by more than 15-25%. ► This is due to the differences in equipment, test system, procedure and evaluation. ► The need for a common standard is obvious. ► A selection out of best practices available is proposed for a standard. ► Improved thermophysical correlations for chlorobenzene/ethylbenzene are proposed.
