Pressure Drop and Holdup in Two-Phase Cocurrent Trickle Flows through Beds of Small Packings

摘要: Correlations were developed and tested for predicting the hydrodynamic performance of cocurrent trickle bed reactors packed with small particles (0.5-1.85 mm). Such show a multiplicity states dependent on past flow history. In general, existing correlations proved adequate although parameters differed from those larger packings an appropriate factor was needed to account history effect. A channelling model which gave satisfactory explanation states.
