New Correlations of Flooding Point and Pressure Drop in Random Packed Tower

Based on the theoretical analysis, new correlations for estimating gas velocity of flood point and pressure drop in random packed tower were derived, and the flooding factor and pressure drop constant of conventional packing were calculated by experimental data. The total mean error between the calculated flooding point gas velocity of eight kinds of packings by new flooding point correlation and the experimental value is 3.52%; the average error between the calculated pressure drop by new pressure drop correlation and the experimental value is generally less than 10%. A fair agreement is found between the calculated and experimental data, and the new correlations are more accurate, simple and convenient than by the equations in literature.
