Abstract A research on pressure drop in a glass column of ID 72 mm with gasliquid counter- and co-current flow was carried out. Mellapack-250X metal corrugated ripple plate structured packing and Dg16 plastic random packing of cascade mini ring were adopted as mass transfer media respectively. Taking H2O-SO2 as research system and combining it with counter-current absorption experiments, we contrastively analyzed pressure drop of packed column with gas-liquid co-current in detail. The influences of gas phase capacity factor F and liquidgas ratio L/V on pressure drop were investigated respectively. Pressure drop increased with the rising of F and L/V. And the influence was less than that with counter-current absorption. Correlation equations of pressure drop were gained from experimental data, which provided theoretical guidance for further process design and optimization.
