Learn why a random packed tower may lose efficiency at low liquid load, including minimum wetting behavior, distributor turndown, channeling, packing material, liquid properties and troubleshooting steps.

Learn why liquid carryover occurs from a random packed tower and how to diagnose flooding, excessive gas velocity, foaming, mist eliminator overload, poor drainage and downstream condensation.

Learn why HETP may increase in a random packed distillation column and how to troubleshoot liquid maldistribution, hydraulic loading, fouling, poor wetting, packing damage and changing process conditions.

Learn how to diagnose liquid maldistribution in a random packed tower, including distributor blockage, wall flow, dry zones, poor turndown, localized flooding and practical corrective actions.

Learn how to diagnose flooding in a random packed tower, including pressure-drop symptoms, gas and liquid overload, fouling, foaming, distributor problems and practical corrective actions.
