Learn why packed towers develop dry spots inside the packing bed, including poor liquid distribution, low liquid loading, channeling, fouling, installation problems, unsuitable packing selection, and scale-up effects. This engineering guide explains how dry spots reduce effective packing area and impact separation performance.

Learn why packed towers experience uneven gas distribution, including poor inlet design, large tower diameter effects, internal problems, packing installation issues, fouling, excessive gas velocity, and operating changes. This engineering guide explains how gas maldistribution reduces packing utilization and separation performance.

Learn why packed towers lose efficiency at high gas velocity, including increased pressure drop, reduced gas-liquid contact, liquid entrainment, lower flooding margin, poor liquid distribution, unsuitable packing selection, and internal limitations. This engineering guide explains how excessive gas velocity affects packed tower performance and how engineers can improve operation stability.

Learn why packed towers lose efficiency at low liquid loading, including poor wetting, reduced gas-liquid contact, channeling, unsuitable packing selection, and operation outside the design range. This engineering guide explains how low liquid flow affects packing utilization and separation performance.

Learn why a packed tower may still have poor separation performance after packing replacement. This engineering guide explains how liquid distribution, packing selection, installation quality, tower internals, operating changes, and hidden limitations can prevent new packing from achieving expected results.
